Environment-friendly and low temperature-resistant acrylate adhesive

Abstract

The invention relates to an environment-friendly and low temperature-resistant acrylate adhesive which comprises the following raw materials in parts by weight: 100 parts of an acrylate adhesive, 0.1-1.0 part of a curing agent, 1.0-5.0 parts of a latent curing agent and 5.0-10.0 part of a low-temperature modifying agent. The invention further relates to a preparation method of the environment-friendly and low temperature-resistant acrylate adhesive. Compared with the prior art, the adhesive provided by the invention is higher in solid content (at least reach 60 percent), lower in relative molecular weight, easier for the introduction of a low-molecular segment and low in solvent content and toxicity, thereby being the environment-friendly adhesive; the initial viscosity is obviously improved in a low-temperature environment, and the adhesive force does not attenuate.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environmentally friendly low-temperature resistant acrylate adhesive. Background technique [0002] With the development of science and technology, various multi-functional and high-performance adhesives have been widely used in various fields of modern industry, making adhesives an indispensable material in modern industry and national defense industry. At present, with the increasingly stringent environmental protection requirements in the market, environmental friendly factors such as high solid content, solvent-free, water-based, and light-curing will receive more and more attention, and research and development efforts will continue to increase. Among them, an important direction of the environmental friendliness of solvent-based adhesives is to increase the solid content of the adhesive, that is, to reduce the solvent content in the adhesive by increasing the effective solid con...

Problems solved by technology

However, in actual operation, the substrate needs to be dried after primer coating, and can be bonded with the tape after drying. This method increases the operation process, increases the production cost, and reduces the production efficiency.

[0004] In addition, double-sided tape is widely used in automobiles, home appliances, electronics and other industries for metal plates (steel plates, aluminum plates, painted panels), plastic plates (PP, PE, ABS, PMMA, etc.), foam (PU, EPDM, etc.) ), felt and other materials, among which PE board, PU foam, EPDM, felt and other materials have low surface energy. It is extremely inconvenient to use after hot pressing to make the adhesion climb to the next step.
