Embodiment 1

[0043] According to the weight percentage of component A, component A includes: 35% epoxy resin (bisphenol A epoxy), 5% toughening agent (carboxyl-terminated liquid nitrile rubber), 20% micro-nano filler (10nm~50μm hydrophobic silica), 3% hydrophobic additive (silicon modified polyacrylate), 20% wear-resistant filler (100 mesh silicon carbide), 15% hydrophobic filler (polytetrafluoroethylene powder) ) and 2% thixotropic agent (hydrophobic fumed silica).

[0044] According to the weight percentage of component B, component B includes: 95% polymethylene diamine modified amine curing agent and 5% curing accelerator (tris-(dimethylaminomethyl) phenol).

[0045] Component A and component B are mixed in a weight ratio of 4:1 to prepare a wear-resistant, anti-sticking high-strength coating.

Embodiment 2

[0047] According to the weight percentage of component A, component A includes: 39% epoxy resin mixture, 2% toughening agent (polyurethane modified toughening agent), 25% micro-nano filler (hydrophobicity of 10nm~50μm Titanium dioxide), 2% hydrophobic additive (silicon modified polyacrylate), 15% wear-resistant filler (100 mesh ceramic particles), 15% hydrophobic filler (polytetrafluoroethylene powder) and 2% thixotropic agent ( hydrophobic fumed silica). The mixed epoxy resin is composed of 50% bisphenol F epoxy resin and 50% bisphenol A epoxy resin.

[0048] According to the weight percentage of component B, component B includes: 90% of aminonut shell modified amine curing agent and 10% of curing accelerator (benzyl alcohol).

[0049] Component A and component B are mixed in a weight ratio of 4:1 to prepare a wear-resistant, anti-sticking high-strength coating.

Embodiment 3

[0051] The difference from Example 1 is that the epoxy resin is an epoxy resin mixture, and the epoxy resin mixture is 80% bisphenol A epoxy resin and 20% novolac epoxy resin.

Abstract

The invention provides a wear-resistant anti-sticking high-strength coating, a composition for forming the wear-resistant anti-sticking high-strength coating, and a conveying device containing the wear-resistant anti-sticking high-strength coating. The composition comprises a component A and a component B, wherein the component A comprises an epoxy resin, the component B comprises a curing agent,and the curing agent comprises a polymethylene diamine modified amine curing agent and / or cashew nut shell oil modified amine curing agent. The coating formed by coating and curing the composition with the components has good wear resistance, good anti-sticking property and high strength. The composition does not contain a solvent, so that the coating forming process does not discharge VOC, and issafety and environmentally friendly.

Description

technical field [0001] The present invention relates to the field of coatings, in particular, to a wear-resistant and anti-sticking high-strength coating, a composition for forming the same, and a conveying device containing the same. Background technique [0002] Superhydrophobic surfaces were invented through the study of the "lotus leaf effect". It has the characteristics of waterproof, self-cleaning, anti-corrosion, anti-icing, etc. It has received more and more attention and attention in theoretical research and industrial applications. A superhydrophobic surface refers to a surface with a contact angle with water droplets greater than 150° and a rolling angle less than 10°. The traditional preparation methods of superhydrophobic surfaces are mainly to construct micro-nano rough structures on the surface of substrates by bionic means, and decorate them with low surface energy substances, or directly construct rough structures on the surface of low surface energy materi...
