Problems solved by technology

[0004] With the rapid development of modern economy and science and technology, the application range of marble is becoming more and more extensive. However, natural marble is fragile and has many cracks. It is difficult to use it in a large area or deal with special shapes. Some adhesives cannot reach the required strength, which greatly affects the application and promotion of artificial marble

Description

technical field [0001] The invention relates to the fields of artificial wood board processing, building block (including other artificial stone) production and circuit insulation board manufacturing, in particular to a novel formaldehyde-free environmental-friendly adhesive and a preparation process thereof. Background technique [0002] At present, people use a lot of adhesives in the production of wood processing and circuit insulation boards, but the adhesives contain various toxic and harmful substances such as formaldehyde and polychlorinated biphenyls, which cannot be completely solved, pollute the environment, and have long-term effects. human health. [0003] The same problem also exists in the construction industry. When the old buildings are demolished, the building blocks become garbage waste. In order to move and transport these wastes, people have to pay a high price. Someone once tried to use cement to bond buildings. In order to achieve the purpose of second...
