 The recent anti-corrosion epoxy powder coating to study the modification. According to experts, industry associations epoxy, epoxy powder coating is a solid composition containing 100% "green paint", with its excellent adhesion, flexibility and excellent corrosion resistance, and corrosion by the anti-life corrosion coatings industry workers of all ages; but the acid and organic solvent resistance is poor, with high water absorption, and poor resistance to boiling water vulnerability greatly limits its application, the study of the epoxy resin system was modified to improve its physical mechanical properties and chemical resistance.glue stick The researchers prepared epoxy powder coating, the experimental process, to set in a more uniform mixture of raw materials, materials used first before using coarse grinding to 50 mesh, and then, to weigh ingredients, mix well and melt mixing 70 ~ 80 ℃ After 20min, cooled to room temperature and then crushed to 180 mesh sieve, which are finished backup. Experiment by adding phenolic resin, epoxy resin matrix was modified; phenolic resin was added to make two kinds of active groups resin crosslinking reaction between the produced, modified from the existing epoxy coating adhesion and flexibility, large, anti- basic good advantage, but also has water resistance of phenolic resin, solvent resistance and excellent acid resistance characteristics. In epoxy resin powder coatings based on the basic recipe, add the adjustment epoxy resin, and phenolic resin and the amount of curing agent.

The current solvent-based polyurethane adhesive to, but the organic solvents flammable, explosive, volatile, smell great, use of air pollution, has some toxicity. With the increasingly strict environmental regulations, the development trend of the world's synthetic adhesive outstanding performance for environmental protection and high performance. Water-soluble polyurethane adhesive for its excellent overall performance, in all kinds of water-soluble adhesive is unique, in recent years widespread glue stick attention at home and abroad, in particular the development of modified water-soluble polyurethane adhesive research has become a hot topic .
