Abstract

The invention relates to the field of chemical engineering, and particularly discloses an environment-friendly adhesive and a preparation method and application thereof. The environment-friendly adhesive comprises a component A and a component B, wherein the component B is a curing agent; the component A is composed of the following raw materials: a vinyl acetate emulsion, a functional monomer, aninorganic filler, an emulsifier, an auxiliary agent, water and a defoaming agent. The environment-friendly adhesive provided by the invention does not contain formaldehyde, benzene substances and other toxic and harmful substances, can be used as a wood adhesive to prepare a plate product, has the advantages of high curing speed, firm adhesion and high weather resistance, and solves the problemsthat most of existing adhesives are not environment-friendly enough and easily cause harm to human health. The preparation method provided by the invention is simple, and the prepared environment-friendly adhesive does not contain formaldehyde, is non-toxic and high in bonding strength, can keep a product not to deform and crack, and belongs to a green and environment-friendly product.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an environment-friendly adhesive and its preparation method and application. Background technique [0002] With the advancement and development of science and technology, people have higher and higher requirements for materials. Among them, the board is made into a flat rectangular building material board of a standard size, which is widely used in the construction industry, and when the board is processed, an adhesive is usually used for bonding. [0003] At present, because adhesives can realize the connection of the same or different materials, they are widely used in many fields such as wood processing, clothing processing, machinery manufacturing, aerospace, transportation, etc. The environmental protection of adhesives has always been a hot spot of concern. Usually, adhesives containing toxic and harmful substances such as formaldehyde and benzene have been the main adhes...
