Problems solved by technology

[0004] 2. From the existing adhesive products and raw material formulas, it can be seen that in order to reduce the raw material cost of the products or because the technology cannot meet the requirements, the manufacturers do not add any flame retardant ingredients to almost all products, and there are no labels on the market. There are "flame retardant" adhesives;
[0005] 3. The waterproof performance of the adhesive is low
Many existing water-emulsion adhesives only have general water resistance and cannot achieve true waterproof function. After encountering water or soaking in water for a period of time, the adhesive film will soften and the bonding parts will come off;
[0006] 4. Poor aging resistance
Otherwise, the adhesive will become discolored and brittle in a short period of time, greatly shortening the service life of the adhesive and the product to be adhered;
[0007] 5. The peel strength between bonding materials is small
Therefore, it is difficult to improve the peel strength between bonding materials;

Abstract

The invention relates to an adhesive material, in particular to an adhesive with a flame-retardant function and a quick bonding characteristic and a preparation method thereof. The adhesive consists of the following raw materials in part by weight: 40.0 to 60.0 parts of solvent oil, 25.0 to 45.0 parts of resin and rubber, 1.0 to 10.0 parts of flame retardant, 0.5 to 5.0 parts of anti-aging agent, 5.0 to 20.0 parts of reinforcing agent and 0.3 to 5.0 parts of aid. The adhesive has the characteristics of high flame retardance, initial viscosity, weather resistance, peel strength and bonding speed, environment friendliness, no toxicity, wide application range and the like, and is suitable for bonding various building materials such as various wood plates, aluminum-plastic plates, cement plates, glass, metal and ceramic surfaces and the like.

Description

technical field [0001] The invention relates to an adhesive material, in particular to an adhesive which is used for bonding various building materials and has flame retardant function and fast bonding characteristics. Background technique [0002] At present, there are many varieties of adhesive materials, especially more adhesives for bonding boards in the construction industry, such as: polyvinyl acetate emulsion for bonding furniture wood, structural adhesives for steel structure connections, and in recent years. All kinds of universal glue and acrylic adhesive, etc. These adhesives all have many common shortcomings, namely: [0003] 1. Since the raw materials are organic resins, rubber, solvents and additives, they are very good flammable materials. They will burn instantly when exposed to fire, which can easily cause fire. In recent years, there have been countless fires caused by flammable building materials in our country, which have caused great losses to people's...
