Embodiment 1

[0013] The invention is a wear-resistant and anti-ultraviolet coating, which is made of the following raw materials in parts by weight:

[0014] 1.2 parts of silicon carbide powder, 0.5 parts of hardener, 6.5 parts of bisphenol A epoxy resin, 2.3 parts of perlite powder, 2.5 parts of dioctyl phthalate, 2.2 parts of OP emulsifier, 0.5 parts of sodium acetate, chlorosulfonated 0.3 parts of polyethylene, 0.2 parts of film-forming aids.

[0015] The film-forming aid is an ether alcohol organic solvent. The hardener is water-based epoxy resin.

Embodiment 2

[0017] The invention is a wear-resistant and anti-ultraviolet coating, which is made of the following raw materials in parts by weight:

[0018] 3.5 parts of silicon carbide powder, 0.8 parts of hardener, 7.8 parts of bisphenol A epoxy resin, 3.6 parts of perlite powder, 4.8 parts of dioctyl phthalate, 5.1 parts of OP emulsifier, 0.8 parts of sodium acetate, chlorosulfonated 0.5 parts of polyethylene, 0.4 parts of film-forming aids.

[0019] The film-forming aid is an ether alcohol organic solvent. The hardener is water-based epoxy resin.

[0020] The wear-resistant and anti-ultraviolet coating provided by the present invention is a good ultraviolet photocuring and scratch-resistant coating. Not only is the source of raw materials convenient, but also both the raw material itself and the finished coating have excellent stability, which is convenient for industrialization and application, and the coating has The characteristics of fast curing speed and simple preparation proc...

Abstract

The invention discloses a wear and ultraviolet resistant coating. The coating is prepared from the following raw materials, by weight, 1.2-3.5 parts of silicon carbide powder, 0.5-0.8 parts of a hardener, 6.5-7.8 parts of bisphenol A epoxy resin, 2.3-3.6 parts of perlite powder, 2.5-4.8 parts of dicapryl phthalate, 2.2-5.1 parts of an OP emulsifier, 0.5-0.8 parts of sodium acetate, 0.3-0.5 parts of chlorosulfonated polyethylene and 0.2-0.4 parts of a film forming assistant. The wear and ultraviolet resistant coating is a good ultraviolet-curable scratch-resistant coating, raw materials are convenient to obtain, and the raw materials and the coating respectively have excellent stability, so the industrial popularization and application of the coating are convenient; the coating also has the characteristics of fast curing speed, simple preparation technology, and substantially reduced production cost; and a coat made by using the coating has the characteristics of moderate hardness, good transmittance and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a wear-resistant and anti-ultraviolet coating, which belongs to the field of coatings. Background technique [0002] Ultraviolet rays account for 5% of the solar spectrum energy, and the wavelength is below 380nm. Ultraviolet rays can cause discoloration of objects and are harmful to the human body, such as cataracts and skin cancer. Therefore, in addition to heat insulation requirements and blocking infrared penetration, heat insulation coatings also require ultraviolet blocking. Generally, in order to block ultraviolet rays, UV absorbers are added to the pressure-sensitive adhesive. These UV absorbers are usually organic and therefore have aging problems. The best way is to add anti-ultraviolet inorganic additives, such as nano-zinc oxide and other substances, to the heat-insulating coating. Blocking ultraviolet rays, in addition to protecting the human body, also has the function of protecting...
