Abstract

The invention discloses a polyurethane acrylate sealant and a preparation method thereof. The sealant comprises the following components by weight: 10-50 parts of polyurethane performed polymer, 5-40 parts of isooctyl acrylate, 1-30 parts of glycidyl methacrylate, 1-5 parts of isobutyl methacrylate, 1-3 parts of vinyl acetate, 3-15 parts of a tackifier, 1-20 parts of a plasticizer, and 0.1-3 parts of an adhesion promoter. The preparation method comprises the following steps: preparing polyurethane performed polymer; adding isooctyl acrylate, glycidyl methacrylate, isobutyl methacrylate, and vinyl acetate into a reaction device, stirring, controlling the temperature of the reaction vessel at 60-80 DEG C, adding the tackifier and the adhesion promoter, cooling to 30-50 DEG C with a cooling device, adding the plasticizer, uniformly dispersing, filtering with a filter, filling the product with an automatic filling device, and storing the product. The purpose of the invention is to provide the polyurethane acrylate sealant with reasonable components and ratios and good adhesive property, and the preparation method thereof.

Description

technical field [0001] The invention relates to a polyurethane acrylate sealant; the invention also relates to a method for preparing the polyurethane acrylate sealant. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding; traditional adhesives have poor adhesion due to unreasonable formula ratios and cannot meet the needs of use. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a polyurethane acrylate sealant with reasonable components and ratio and good bonding performance. [0004] Another object of the present invention is to pro...
