Problems solved by technology

Building roofs are usually composed of metal materials and non-metal materials. Therefore, the adhesive for bonding building roofs needs to have good bonding performance for both metal materials and non-metal materials. Adhesives on the market are usually suitable for single materials. It plays the role of bonding, and it is difficult to play a good bonding effect on metal materials and non-metal materials at the same time

Abstract

The invention relates to an adhesive for an environment-friendly building top plate. The adhesive is prepared from ethylene glycol dimethacrylate, methyl methacrylate, polystyrene, phthalic anhydride,lead oxide, polysulfide rubber, talc powder, barium sulfate and toluene diisocyanate. According to the adhesive for the environment-friendly building top plate, the ethylene glycol dimethacrylate, the lead ooxide, the polysulfide rubber, the talc powder, the barium sulfate and the toluene diisocyanate synergistically act to achieve stable performance, enhance the adhesion performance of the adhesive, achieve a good adhesion effect on both a metal material and a nonmetal material, reduce gaps existing between building top plates and improve the mechanical strength and waterproofness of the building top plate.

Description

technical field [0001] The invention relates to the technical field of adhesive production, in particular to an adhesive for an environmentally friendly building roof. Background technique [0002] Adhesives are also known as adhesives, binders, commonly known as glue. It is a substance that binds the surface of an object to the surface of another object. Adhesive can bond various same or different materials, especially suitable for bonding materials with large difference in elastic modulus and thickness, and it is not suitable to use other edge joining methods, especially suitable for bonding elastic modulus and thick thickness The difference is relatively large, and it is not suitable to use other connecting materials, as well as sheet or film materials. Adhesives come in many varieties and have different compositions, but they are usually a kind of mixture, which is composed of base material, curing agent, accelerator, filler, plasticizer or toughening agent, diluent an...
