Inorganic composite coating, method for coating surface of building material by applying same and building material

Abstract

The invention discloses an inorganic composite coating with safety, no pollution, energy-saving, high hardness and strong non-sticking property, a method for coating the surface of a building materialby applying the same and the building material. The inorganic composite coating comprises a component A and a component B which are independently subpackaged and are combined to be used; the component B is an inorganic film forming accelerant; the component A comprises aluminum oxide, titanium dioxide, silicon dioxide, kaoline, a resin solution and an organic solvent; and all the components are proportioned in percentage by weight as follows: 16%-24% of aluminum oxide, 16%-24% of titanium dioxide, 2%-8% of silicon dioxide, 2%-8% of kaoline, 2%-18% of resin solution, 2%-18% of organic solventand 27%-33% of inorganic film forming accelerant.

Description

technical field [0001] The invention relates to an inorganic composite coating and the application of the inorganic composite coating on building materials. Background technique [0002] At present, in the field of building materials, the surface of metal, ceramics, and engineering plastics used in household, industry, and military applications usually has the following treatment methods: [0003] 1. Directly use bare profiles, such as bare aluminum or stainless steel, without any protection. This method mainly has the following technical defects: ① For example, the surface of profiles used on kitchen utensils is easy to oxidize, and bare pipe profiles In contact with the heated substance at high temperature, there will be water vapor or salt, acid, etc., which will accelerate the formation of an oxide layer, causing the heat dissipation on the surface of the pipe to fail, and the heat of the heating element will not dissipate, which will accelerate the aging of the product;...

Problems solved by technology

[0003] 1. Directly use bare profiles, such as bare aluminum or stainless steel, without any protection. This method mainly has the following technical defects: ① For example, the surface of profiles used on kitchen utensils is easy to oxidize, and bare pipe profiles In contact with the heated substance at high temperature, there will be water vapor or salt, acid, etc., which will accelerate the formation of an oxide layer, causing the heat dissipation on the surface of the pipe to fail, and the heat of the heating element will not dissipate, which will accelerate the aging of the product; ② Not resistant to acid and alkali: The heated substance will contain various kinds of moisture, salt, acid or alkali, and the naked metal profile will be oxidized at any time, causing the heat dissipation of the product to fail

It blocks the heat conduction of the heating pipe, causing the pipe to burst faster

④Unsafe: After there is dirt on the metal surface of the bare heating tube, because the dirt is a bad conductor of heat, the heat of the heating tube cannot be dissipated, causing the tube to burst, and there will be a safety problem of leakage

⑤ No energy saving, short life: After the surface of the light-emitting tube is dirty, the heat dissipation on the surface of the tube is poor, and the heat generated by the heating tube cannot be fully absorbed by the heated substance

The main disadvantages of this treatment method are: ① not environmentally friendly, large environmental pollution, easy to oxidize

②Not resistant to fire, acid and salt

③No energy saving, usually expensive maintenance costs

④Fast discoloration, easy to crack and peel off

The hardness of the coating material is low, not more than 1.5H, not wear-resistant and easy to scratch

⑤ Not resistant to ultraviolet rays, easy to change color indoors and outdoors

[0005] 3. Electroplating or electrophoresis anti-corrosion process is adopted on the surface of building materials. The main formula includes degreasing liquid, etching liquid, polishing agent, pre-plating agent and other solvents, as well as heavy metals such as nickel and copper. The main defects of this method are: it is not environmentally friendly and can High consumption, great environmental pollution: strong acid or strong alkali, harmful and long-lasting, heavy metal pollution that is difficult to handle

The main disadvantages of this treatment method are: ① Not environmentally friendly: a toxic gas will be produced when heated, which will cause great harm to the human body, and the hidden chemical substances can only be discovered after 30 years.

②Unsafe: When exposed to high temperatures above 260°C, there will be open flames and thick smoke, which will cause great harm to the human body

④Complicated processing: need to spray three layers, high loss rate

⑤Low hardness, not wear-resistant: the hardness is only 1.5H

⑥ Not sticky, poor self-cleaning
