Problems solved by technology

However, the raw materials in the above-mentioned environmentally friendly adhesives use a large amount of solvents and aromatic diisocyanates. When encountering hot weather or strong ultraviolet radiation, the release of aromatic poisons will be accelerated, and heavy metals such as lead and mercury will remain, which have strong chronic toxicity to the human body. And it will also cause continuous pollution to the soil environment and groundwater; moreover, a large amount of silicon dioxide is added to the above-mentioned adhesive, and as the content of silicon dioxide increases, the adhesive is prone to cracking

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy and the continuous progress of the society, adhesives and bonding technology have shown incomparable vigor and vitality, their importance is increasing day by day, and their practicability is eye-catching. Adhesives are widely used in people's daily life, and their environmental protection issues have also been paid attention to. Many organic compound raw materials used in the development of traditional adhesives, especially toxic and harmful solvents and thinners, are harmful to the environment. Pollutants and human body The harm is greater, therefore, the need for environmentally friendly adhesives is imminent. [0003] Currently commonly used adhesives mainly use formaldehyde as the main raw material for production, ...
