Acrylate adhesive and preparation method thereof

Abstract

The invention discloses an acrylate adhesive, which is composed of the following components in parts by mass: 90-100 parts of methyl methacrylate, 5-8 parts of methacrylic acid, Polymethyl methacrylate molding powder 25~30 parts, diethylaniline 0.1~0.2 parts, methyl ethyl ketone peroxide 0.1~0.2 parts, cobalt naphthenate 0.05~0.1 parts, acrylic acid 5~10 parts, phthalic acid 2~3 parts of dibutyl ester. The preparation method is as follows: Weigh each component of the above formula in sequence, stir evenly in the reaction kettle, and cure for 24 hours under the pressure of 0.1~0.2MPa and room temperature to obtain the finished product. The acrylate adhesive prepared by the invention can be used for bonding metal materials such as iron, copper, aluminum alloy, etc., and the bonding strength is greatly improved.

Description

technical field [0001] The invention relates to an acrylate adhesive and a preparation method thereof, which are applied in the technical field of adhesive processing. Background technique [0002] Adhesive refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives. It has the characteristics of continuous stress distribution and light weight. With the development of society, the field of adhesives has developed rapidly, and there are more and more types of adhesives. The market Adhesives used in the bonding of metal materials such as iron, copper, and aluminum alloys generally have the disadvantage of insufficient bonding strength, and the shear strength between materials after bonding is insufficient, which has certain limitations. Contents of the invention [0003] In order to solve the above problems, the invention discloses an acrylate adhesive and a preparation method thereof. [0004] The invention discloses an acryla...
