The origin of this paper
On April 16, 2020, in the club group of "technology and application of hot melt pressure sensitive adhesive", I initiated the theme discussion on the development trend of hot melt adhesive. My problem is: the epidemic is worldwide, more than 2 million people have been diagnosed. Due to the sudden increase in the market of masks and protective clothing, the prices of health products and medical tapes have skyrocketed, and there is no supply, but the supply of hot melt adhesive is stable and the price is stable. After the epidemic, how will the hot melt adhesive market develop? What is the impact of the epidemic on the hot melt adhesive industry? More than ten group Friends participated in the discussion and shared a lot of valuable views. With regard to the development of tackifying resin industry, we discussed it in depth, so we specially arranged it and kept it as a data of the industry.

Basic information
At present, China is a big country in the production and sales of tackifier resins such as petroleum resin and rosin resin, and the production and sales are all in the forefront of the world. Tackifier is an important hot-melt collagen material, and it is widely used in other industries such as adhesives, inks, papermaking, etc. Tackifier is the most important raw material of hot-melt adhesive. It can reduce the melting viscosity of hot-melt adhesive, improve its wettability and initial viscosity to the glued joint, and adjust the heat-resistant temperature and drying time of the adhesive. The dosage is about half of the total amount of hot-melt adhesive. Hot melt adhesive requires good compatibility between tackifier and basic polymer, good adhesion to adherend and good thermal stability at melting temperature. Its main types are: (1) petrochemical and coking: non hydrogenated C5 resin and C9 resin, hydrogenated C5 resin and hydrogenated C9 resin, DCPD and their copolymers, low molecular weight polystyrene, thermoplastic phenolic resin, low molecular weight silicone, low molecular weight acrylic resin; (2) natural resin: Rosin (including gum rosin, wood rosin, oil sliced rosin, etc.), modified rosin (including hydrogenated rosin, disproportionated rosin, polymeric rosin, etc.), rosin resin (including rosin glyceride, pentaerythritol, etc.); Terpene resin and its modified terpene resin. 03
Influence of epidemic situation on the market of tackifier resin
Dr. David Hao, East China University of science and technology, said: as a resin producer in the world, China's export has been hindered obviously with the development of the epidemic, and China's domestic demand has gradually increased with the improvement of the epidemic, but it can't offset such a large margin of export. In addition, the global chess game, a part of the downstream is also exported, so the world epidemic, especially in Europe and America, is under control If the system is not good, the trend of resin oversupply is obvious. In addition, for ordinary resin, the actual domestic production capacity has long exceeded the current domestic demand, and we must break through the international market. In addition to the imbalance of supply and demand caused by the epidemic in the short term, as Mr. Cao Dewang said, after the epidemic, the trend of going to China will have some performance, and foreign factories may also retain a certain proportion of local suppliers from this perspective, rather than only looking at cost performance, which should be a long-term impact. However, at present, at least in the resin industry, the common resin with low added value is exported, while the fine brand resin with high added value is mostly imported. This epidemic also affects the supply of this resin for domestic enterprises. On the one hand, the supply of common products exceeds the demand, and on the other hand, the supply of good products from east to west is insufficient, which will force the domestic resin industry to develop. In the long run, it's not necessarily a bad thing. China's history has proved that we have achieved the world's advanced level for those who are surrounded by the outside world, and we have imitated and spelled out prices for those who are given by the outside world. I firmly believe that this situation, in the long run, is a good thing and can promote the industrial upgrading we have always wanted to do. 04
Advanced learning
In terms of high-end products, Chinese enterprises should learn more from the advanced ones. As a big producer and seller of tackifier, why do we need to import so many tackifier with high price? 1. Basic research: European, American and Japanese enterprises are more solid and in-depth than domestic ones, while China's resin industry needs more basic theoretical research. The international brands have invested heavily in the research and development of new products, instead of following other enterprises to copy. In terms of high temperature resistance, strong peeling, high hydrogenation, low odor and other aspects, they have been leading the industry and constantly launched new products. 2. Stick to the industry's deep work: Ji yunyun, a member of the rosin industry, made a speech in the group discussion. In the rosin industry, with some European and American enterprises disliking the business of rosin, they make less money and less investment, so it's also an opportunity for our domestic enterprises, especially the bosses of the rosin industry, who are very emotional, but Japanese enterprises, as always It is worth learning to persist in, to deepen and to concentrate on research. 3. Continuous stability of products: in terms of the continuous stability of products, international multinational enterprises have done better. They are very cautious about changes in product formula, production process and standards, so their products are more stable and trusted by high-end brand enterprises. Because of the lack of flexibility, the market response is slow, and many opportunities are lost. 4. Theory construction: thought determines behavior and theory guides practice. China's Resin enterprises need to improve their technical theory construction, learn and research industry technical theory, learn from advanced technology theory construction such as standards, and pay more attention to the theory. 05
Some ideas
In the tackifier industry, China's relevant practitioners are amazing. In a few years, they have completed the replacement of domestic products with imported ones, greatly reduced the price of products, promoted the popularization and application of hot melt adhesive products, promoted the automation process of China's manufacturing industry, and enabled people to buy goods with good quality and low price. I have observed that many tackifier companies in China have increased investment in R & D, hired professionals, built R & D teams, created innovative laboratories, purchased advanced R & D equipment, conducted customer application research, and conducted basic theoretical research. This shows that from made in China to created in China, China's tackifier companies are taking action and believe that in the near future, in terms of high-end tackifier, China will definitely lead the world. Due to the epidemic in the world and the shortage of medical materials such as masks and protective clothing, the developed countries in Europe and America are aware of the importance of traditional manufacturing industry. They believe that after the epidemic, the developed countries in Europe and America will reconstruct their industrial structure and maintain a certain amount of traditional manufacturing industry with low profits.
