Problems solved by technology

At present, there are no related products on the market, but in terms of published research literature, Sun Xianzhi et al. reported a fluorine-containing acrylate structural adhesive, which has good water resistance, and its adhesion to aluminum sheets has reached 28.89%. Mpa, however, its system is mainly composed of acrylic monomers, which will inevitably shrink when solidified on the surface of low surface energy, seriously affecting the curing effect, and this system also has problems such as strong odor, polluting the environment, and low fault tolerance.

Abstract

The invention discloses a fluorine-containing acrylate structure adhesive and a use method thereof. The fluorine-containing acrylate structure adhesive is prepared from the following components in parts by weight: 10-20 parts of a fluorine-containing acrylate monomer; 10 to 35 parts of an acrylate soft monomer; 40 to 50 parts of an acrylate hard monomer; 14-16 parts of a functional monomer; 0.05 to 0.07 part of a thermal initiator; and 100 to 120 parts of a solvent. The fluorine-containing acrylate monomer is introduced into an acrylate adhesive system, the adhesive is applied to adhesion of fluorine-containing low-surface-energy materials such as polytetrafluoroethylene for the first time, an excellent adhesion effect is achieved, and high innovativeness and practical value are achieved. Meanwhile, the fluorine-containing resin is cross-linked by using the curing agent to form a three-dimensional network, and compared with non-cross-linked fluorine-containing resin, the durability and the bonding strength are remarkably improved.

Description

Technical field [0001] The present invention relates to the field of structural adhesive, and more particularly to a fluorine-containing acrylate structural adhesive and a method of use. Background technique [0002] The gelatin adhesive generally refers to an adhesive applied to the power component which is usually in a thermosetting resin as a raw material, which is adequately solidified by heating and the like, and achieves adhesive effect. Among them, acrylate structural adhesives have been widely used in high strength, impact resistance, aging, strong adhesiveness, etc. However, no matter which adhesive is unable to achieve bonding of fluorine or low surface energy materials such as polytetrafluoroethylene. The reason is that the low surface energy characteristics of these materials make a general adhesive simply unable to spread and infiltrate their surfaces, and thereby unable to achieve bonding. The fluorine-containing acrylate adhesive is expected to solve this problem, ...
