Adhesive for building board

Abstract

The invention relates to an adhesive for a building board and relates to the technical field of building materials. The adhesive for the building board is prepared from, by weight, 10-15 parts of phenolic resin, 5-15 parts of polyacrylate salt, 10-20 parts of talcum powder, 5-10 parts of chitosan, 5-15 parts of calcium carbonate, 5-20 parts of zinc oxide, 5-10 parts of propylene glycol methyl ether acetate, 10-20 parts of special organosilicone coupling agent, 10-30 parts of acetic ether, 5-10 parts of polyethylene glycol, 5-10 parts of ammonium chloride, 20-30 parts of ethyl orthosilicate, 5-10 parts of polyvinyl alcohol, 5-10 parts of ethylene propylene rubber, 5-10 part of nano rubber powder, and 5-20 parts of borax. The adhesive makes full use of the waste materials, achieves recycling of the waste materials, turns waste into treasure, saves the raw materials, and is an environment-friendly adhesive; the bonding property is good, the bonding strength is high, the water resistance is good, and the adhesive for the building board can be used for bonding of an adhesive-bonded board, a fiber board, metal, ceramics and glass materials.

Description

technical field [0001] The invention relates to a building plate adhesive and relates to the technical field of building materials. Background technique [0002] At present, there are many types of adhesives. Due to the different raw materials, the properties of the adhesives vary greatly according to their respective components. However, most adhesives, such as phenolic resin adhesives, contain harmful substances such as benzene, toluene, xylene, and formaldehyde. , Long-term use not only pollutes the environment, but also damages human health. In addition, the manufacturing process of these adhesives is relatively complicated and the cost is high. The amount of polystyrene foam plastics and rubber products in my country is increasing, and most of them are for one-time use. Millions of tons of white garbage and waste rubber products are scattered in nature and cannot be rotten and transformed, nor can they be naturally degraded. Serious pollution is formed.

[0002] At present, there are many types of adhesives. Due to the different raw materials, the properties of the adhesives vary greatly according to their respective components. However, most adhesives, such as phenolic resin adhesives, contain harmful substances such as benzene, toluene, xylene, and formaldehyde. , long-term use not only pollutes the environment, but also damages human health. In addition, the manufacturing process of these adhesives is relatively complicated and the cost is high

The amount of polystyrene foam plastics and rubber products in my country is increasing, and most of them are for one-time use. Millions of tons of white garbage and waste rubber products are scattered in nature and cannot be rotten and transformed, nor can they be naturally degraded. Serious pollution is formed. The current treatment methods for these pollutants are generally incineration and landfill. Among them, landfill will occupy a large amount of land, and incineration will cause new air pollution problems.
