Abstract

The invention relates to a novel environmental-friendly double-component acrylate adhesive, which is composed of a component A and a component B in mass part ratio of 1 to 1, wherein the component A is composed of the following raw materials in mass part: 45-75 parts of acrylic monomer, 15-45 parts of toughened resin, 0.5-10 parts of initiating agent, 0.01-1 part of stabilizing agent, 0.1-5 parts of coupling agent and 0.5-10 parts of thixotropic agent; and moreover, the component B is composed of the following raw materials in mass part: 45-75 parts of acrylic monomer, 15-45 parts of toughened resin, 0.5-10 parts of accelerating agent, 0.01-1 part of stabilizing agent, 0.1-5 parts of coupling agent and 0.5-10 parts of thixotropic agent. The novel environmental-friendly double-component acrylate adhesive provided by the invention has very little smell, does not produce substances harmful to the body, and cannot cause pollution to the environment; and meanwhile, the adhesive with the structure has favorable adhesive property and storage stability.

Description

technical field [0001] The invention relates to an adhesive, in particular to a low-odor, environment-friendly two-component acrylic structural adhesive and a preparation method thereof. Background technique [0002] The second-generation acrylate adhesive has the advantages of fast curing, high strength, good toughness, and strong adaptability, and has been widely used in many fields. However, most of the acrylic structural adhesives currently used in the market have the problem of strong odor, which will cause obvious irritation to the human body. Some adhesives even use carcinogenic aniline and its derivatives as accelerators, and their toxicity The harm to human health and the environment is more serious. With the progress of society and the enhancement of people's awareness of environmental protection, it is particularly necessary to develop an environmentally friendly two-component acrylic structural adhesive with low odor, no harm to the human body and the environmen...
