Embodiment 1

[0031] Embodiment 1 (by weight part)

[0032]

[0033]

[0034]According to the proportioning, YD128, SQE172, DINP plasticizer and PET resin in the above-mentioned Example 1 components were kneaded for 15 minutes at 65°C and the rotation speed was 180 rpm, and then talcum powder and dicyandiamide were added to the kneader. Mix for 10 minutes, finally add ATP, C5, carbon black and the remaining talcum powder, and knead for 40 minutes.

[0035] The matrix composite resin is extruded from the extrusion die with adjusted thickness, and the glass fiber cloth is placed on top and the release paper is placed on the matrix composition at the same time, and then passed through multiple pressure rollers, after cooling, it is cut by an automatic cutting machine To the required size, a 2.0mm thick reinforced film is obtained. The temperature of the extrusion die and the pressure roller is both 60°C, and the temperature of the cooling machine is set at -5°C, which is recorded as REP1...

Abstract

The invention provides a thin plate reinforcing adhesive matrix composition for welding, a reinforcing film and a preparation method, which relate to the field of automotive materials, and include the following components based on the total amount of the matrix composition: 15-35wt% epoxy Resin, 2-15wt% thermoplastic, 30-50wt% inorganic filler, 3-7wt% curing agent, 3-10wt% auxiliary agent, 0.1-1wt% expansion agent, 1.5-4wt% inhibitor. The present invention adopts thermoplastics, which have good thermoplastic cohesion, and can improve the adhesion between the matrix composition and the upper layer of glass fiber cloth; thermoplastics contain lone pairs of electrons, which can be used as electron donors to provide electrons with metal ions on the surface of the steel plate. Electron acceptor empty orbitals attract each other, which also improves the adhesion between the steel plate and the reinforcing sheet matrix composition; moreover, thermoplastics have good compatibility with epoxy resins, and have high tensile strength and good toughness, which can Toughened epoxy resin itself can also be used to prepare structural plastics, provide mechanical strength, and can prepare reinforced films with high reinforcement multiples.

Description

technical field [0001] The invention relates to the field of materials for automobiles, in particular to a thin plate reinforcing adhesive matrix composition for welding, a reinforcing film and a preparation method. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for automobiles, and automobile lightweight and environmental protection have gradually become the trend of automobile development. Automobile lightweight is also an effective way to save energy and reduce pollution. At present, an economical and effective way to reduce the weight of automobiles is to use thin steel plates as automobile materials to reduce the weight of the car body. The thinner steel plates will reduce the local rigidity of the car body, which will easily generate noise and resonance when the car is running, and the impact resistance will deteriorate. to the driver's life. In order to ensure the safety of car drivers,...
