Problems solved by technology

[0005] As early as the 1970s, there were Japanese and U.S. patents introducing the preparation methods of solution-type and emulsion-type diallyl phthalate resins. When preparing solution-type diallyl phthalate resins, a large amount of organic Solvents, and recycling is troublesome, which will not only pollute the environment, but also increase the cost
Emulsion-type diallyl phthalate resin is also rarely used because of emulsion performance and other issues

Abstract

The invention discloses a diallyl phthalate emulsion adhesive and the synthesis method and the application thereof. The adhesive is a green environmental protection formaldehyde-free adhesive obtained by emulsion-copolymerizing diallyl phthalate and a compound containing double bonds, wherein the adhesive is prepared from diallyl phthalate, the compound containing double bonds, distilled water, an emulsifying agent and an initiator in the weight ratio of 1:(0.05 to 1):(0.8 to 1.5):(0.01 to 0.2):(0.01 to 0.1). The synthesis method comprises the following steps: pre-emulsifying diallyl phthalate, distilled water, the compound containing double bonds and the emulsifying agent in the presence of nitrogen; adding the initiator according to the ratio; and carrying out emulsion copolymerization reaction in the presence of nitrogen to obtain the adhesive with no free formaldehyde, no environmental pollution, no damage to human bodies, no need of organic solvent in the synthesis process, low cost, good stability, easy storage, and high bonding strength. Impregnated paper prepared by using the adhesive can be directly subjected to hot pressing to obtain decorative boards, and the hot pressing process is simple and easy to control.

Description

1. Technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a diallyl phthalate emulsion adhesive used for surface decoration of wood-based panels, a synthesis method and application thereof. 2. Background technology [0002] Since the reform and opening up, with the development of the construction market and home improvement industry, the consumer market such as decoration and furniture industry has grown rapidly, and my country's wood-based panels have also achieved sustained, stable, and high-speed development. However, the adhesive used in the production of wood-based panels is still based on urea-formaldehyde resin. Glue, phenolic resin glue and melamine glue (referred to as "trialdehyde glue") are mainly used, which causes the free formaldehyde in many wood-based panels to be released into the air, causing pollution to the production environment and use environment of furniture. Therefore, it is very necessary to produ...
