Abstract

The invention relates to a multipurpose adhesive. The multipurpose adhesive is specifically prepared from the following components in parts by mass: 35 to 45 parts of chloroprene rubber, 10 to 15 parts of styrene, 25 to 40 parts of waterborne polyurethane resin, 2 to 5 parts of a dispersant, 5 to 8 parts of toluene, 3 to 9 parts of dimethyl carbonate, 1 to 4 parts of dichloropropane, 35 to 40 parts of methyl methacrylate, 1 to 4 parts of an emulsifier and 0.07 to 0.2 part of a catalyst. An experiment shows that the multipurpose adhesive provided by the invention has the characteristics that the dynamic viscosity is 9.7Pa.s or more and the peeling strength is 6.1kg / 25mm or more; an existing multipurpose adhesive has the characteristics that the dynamic viscosity only can reach 8.9Pa.s and the peeling strength is only 4.9kg / 25mm; it can be seen that adhering performances including the viscosity, the peeling strength and the like of the adhesive are greatly improved through improving raw materials and a production process of the adhesive; the multipurpose adhesive has a remarkable effect and a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a multi-purpose adhesive. Background technique [0002] Multi-purpose adhesive, mainly used for metal nameplates, foam plastics, wood, tiles, metal bonding or mutual bonding, has the advantages of curing at room temperature, wide range of bonding materials, and good water resistance. [0003] As a kind of adhesive, multi-purpose adhesive needs to continuously improve its performance indicators such as viscosity and peel strength. However, the raw materials and production process of multi-purpose adhesive have not changed for a long time, and the performance of multi-purpose adhesive cannot be further improved. Contents of the invention [0004] In order to solve the above problems, the present invention provides a multi-purpose adhesive. [0005] The present invention is realized through the following technical solutions: [0006] A multi-purpose adhesiv...
