Abstract

The invention relates to the technical field of adhesives, in particular to a high-adhesiveness acrylate adhesive and a process for preparing the same. Raw materials for preparing the high-adhesiveness acrylate adhesive comprise the following components in parts by weight: 700 parts of methyl methacrylate, 120 parts of 2-ethylhexyl acrylate, 80 parts of acrylic acid, 1500 parts of ethyl acetate, 7 parts of 2-hydroxyethyl acrylate, 150 parts of rosin resin, 50 parts of hydroxyl end-capping polymethyl silicone oil and 5 parts of ferric hydroxide. No methylbenzene is volatilized from a downstream product of the product and the environmental friendliness is good; meanwhile, since the preparation process provided by the invention adopts a step-by-step charging method, the implosion is effectively prevented from occurring, the dispersity of the product is high, the VOC (volatile organic compounds) content of the downstream product is obviously reduced and most importantly, the adhesiveness is improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-viscosity acrylate adhesive and a preparation process thereof. Background technique [0002] Adhesive, also known as adhesive, referred to as glue (bonding agent, adhesive), is a non-metallic medium material that makes an object closely connected with another object. The adhesive only occupies a very thin layer of volume between the two adherend surfaces, but after the adhesive is used to complete the bonding construction, the obtained adhesive joints can meet various requirements of actual needs in terms of mechanical properties and physical and chemical properties. It can effectively bond materials together. [0003] Acrylic adhesives have a wide range of raw materials, simple preparation process, rapid drying and molding, good transparency, good bonding performance to various materials, and good weather resistance, water resistance, and chemical resistance. In parti...
