The invention discloses a strong acid and alkali resistant plastic material for fume hood surface decoration and a preparation method of the strong acid and alkali resistant plastic material, belongs to the technical field of plastic material processing, and aims at solving the technical problem that in the prior art, the acid and alkali resistance and the bending modulus of a plastic material for fume hood surface decoration need to be further improved. The preparation method specifically comprises the following steps: stirring amino-modified fluorosilicone resin, paraformaldehyde and 1, 4-dioxane in a reaction kettle, dropwise adding an anacardol solution, heating the reaction kettle to 85-95 DEG C, carrying out heat preservation reaction for 6-8 hours, and carrying out post-treatment to obtain the anacardol-based benzoxazine resin. Perfluoro-modified polysiloxane benzoxazine is prepared, naphthalene-containing epoxy resin and imidazole-modified silicon carbide microspheres are compounded, in-situ catalysis synergistic curing is carried out by using filler interface imidazole, a compact organic-inorganic hybrid interpenetrating network is constructed, and the strong acid and alkali corrosion resistance and bending modulus of the material are remarkably improved.

The application belongs to the field of coatings, and provides a coating composition for an ink surface and a preparation method thereof, the preparation method comprising the following steps: mixing a zwitterionic monomer, an acrylate monomer and a hydroxy acrylate monomer, heating and reacting to obtain a polymerized monomer; adding a hydrophobic compound to the polymerized monomer, heating and reacting to obtain a hydrophobic monomer, then adding an anhydride to the hydrophobic monomer, continuing to heat and react to obtain a carboxyl monomer; adding a long-chain alkyl monomer to the carboxyl monomer, heating and reacting to obtain a long-chain polymer, then dispersing the long-chain polymer in deionized water, adding a photoinitiator and a functional additive, stirring and dispersing to obtain the coating composition. The coating composition prepared by the above method can effectively improve the water resistance and adhesion of water-based acrylate ink in a high-humidity environment.

This application relates to the field of wave soldering carrier technology, and provides a wave soldering carrier and wave soldering equipment. The wave soldering carrier includes: a carrier body, the carrier body having an upper carrier surface and a lower carrier surface disposed opposite to each other, the upper carrier surface having a first bearing area and a second bearing area, the first bearing area being used to support the main body section, and the second bearing area being used to support the reinforcing section; the second bearing area having a reinforcing limiting groove, the reinforcing limiting groove being used to limit at least a portion of the reinforcing section having a reinforcing plate, the bottom wall of the reinforcing limiting groove having a first clearance opening communicating with the lower carrier surface, when the flexible circuit board is loaded on the carrier body, the pins of the device to be soldered extend into the first clearance opening through the reinforcing plate and the flexible circuit board, and the bottom end of the pin is flush with the lower carrier surface, or the bottom end of the pin protrudes from the lower carrier surface.
