This invention relates to a high-reliability solder resist coating, its preparation method, and its application. The raw materials, by weight, include 40-50 parts of alkali-soluble resin, 10-20 parts of acrylate monomer, 1-5 parts of photoinitiator, 0.1-0.5 parts of pigment, 0.1-0.3 parts of additives, and 30-45 parts of filler. The alkali-soluble resin is bisphenol A epoxy diacrylate resin, and the filler includes at least modified barium sulfate. This invention synergistically combines bisphenol A epoxy diacrylate resin with modified barium sulfate to achieve a synergistic improvement in mechanical properties and resistance to damp heat, solving the problems of insufficient mechanical properties, poor resistance to damp heat, and difficulty in passing the stringent 85 dual-85 test of existing solder resist dry films. The solder resist dry film can meet the usage requirements of high-end printed circuit boards in harsh damp heat environments, improving the service life and reliability of printed circuit boards.

This invention discloses a polymer material technology field, specifically an impact-resistant lens resin monomer, its preparation method, and its production system. The raw materials, by weight, include: 60-80 parts epoxy acrylate, 15-25 parts polycaprolactone diacrylate, 1-3 parts dicumyl peroxide, 0.5-1.5 parts antioxidant 1010, 0.3-1.0 parts ultraviolet absorber UV-327, 0.3-0.8 parts γ-methacryloyloxypropyltrimethoxysilane, and 1-3 parts nano-silica.

This invention discloses a PLA coating composite material, its preparation method, and its application, belonging to the field of coated paper technology. The composite material comprises the following raw materials in parts by weight: 70-80 parts of polylactic acid; 20-30 parts of bio-based toughening component; 15-25 parts of cationic filler; 2-4 parts of heat-resistant compatibilizer; and 1 part of nucleating agent TMC-3001. The heat-resistant compatibilizer is a terpolymer formed by norbornene imide, 1,6-hexanediol diacrylate, and glycidyl methacrylate. The PLA coating composite material provided in this application constructs an "organic-inorganic" dual reinforcement system through the synergistic effect of the heat-resistant compatibilizer and the cationic filler, which not only strengthens the material's intrinsic properties but also improves the interfacial bonding strength between the coating layer and the paper. Ultimately, a fully biodegradable coating material with high heat resistance, excellent flexibility, and strong interlayer bonding is obtained. This fully biodegradable coating material is suitable for preparing heat-resistant coated paper products.
