Abstract

The invention discloses an environment-friendly pressure-sensitive adhesive, which is characterized by comprising the following components in parts by weight: 20-30 parts of amino triazine modified C5petroleum resin, 3-6 parts of 3-chlorine-3-(4-fluorine phenyl) acrylonitrile ionized modified 4-fluorine phenyl boric acid methyl iminodiacetate, 10-20 parts of 2-acrylic acid-hexahydro-4, 7-methylene-1H-indenyl ester / glyceryl allyl ether / 4-propenyloxy- 2-hydroxy benzophenone / 4-methacrylamido salicylic acid copolymer, 3-6 parts of epoxy-terminated hyperbranched poly (amine ester) and 4-8 parts ofa reactive diluent. The invention also provides a preparation method of the environment-friendly pressure-sensitive adhesive. The environment-friendly pressure-sensitive adhesive disclosed by the invention is good in environment-friendliness, good in performance stability, good in water resistance, weather resistance and high and low temperature resistance, high in bonding strength and excellentin comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy and the continuous improvement of living standards, people's desire to improve the quality of life has become more and more urgent, and their understanding of environmental issues has become more and more in-depth. High-end products are an inevitable trend at this stage and even for a period of time in the future. These products have always been "market stars" and have great potential for development. [0003] Adhesive refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesive, which has the characteristics of continuous stress distribution, high viscosity, no glue residue, light weight, and convenient use. Gluing is especially suitable for the connection of ...
