preparation example Construction

[0026] The preparation method of the reinforced film of the present invention may be to attach the reinforcing layer on one surface of the reinforced film substrate of the present invention to obtain a reinforced film. It is also possible to compress the kneaded reinforced film matrix composition and the reinforcing layer together. It can also be that the release paper and the reinforcement layer are clamped and kneaded to form a reinforced film matrix composition, and then placed on a molding device to be pressed into a sheet. The invention is not limited.

[0027] The present invention also provides a steel plate composite material, which comprises a steel plate bonded together in sequence, a reinforcing film matrix and a reinforcement layer, and the reinforcing film matrix is ​​the above-mentioned reinforcing film matrix. Wherein, preferably, the thickness ratio of the steel plate, the reinforcing film substrate and the reinforcing layer may be 0.6-1.2:0.5-5:0.05-2. Where...

Abstract

The invention provides a stiffener film substrate composition, a stiffener film substrate, a stiffener film and a steel plate composite material comprising the stiffener film. The stiffener film substrate composition comprises epoxy resin, nitrile rubber, butadiene styrene rubber, a curing agent and a tackifier. The prepared stiffener film substrate has strong bonding force with a vehicle body steel plate, the strength of the cured stiffener film substrate is further improved, meanwhile, the vibration noise of a vehicle body can be reduced, and the NVH (Noise Vibration and Harshness) property of a vehicle can be enhanced.

Description

technical field [0001] The invention relates to a reinforced film matrix composition, a reinforced film matrix prepared from the composition, a reinforced film, and a steel plate composite material comprising the reinforced film. Background technique [0002] With the development of technology and the continuous improvement of automobile quality, automobiles are developing in the direction of high speed, light weight, energy saving and comfort. (Harshness)) requirements are also getting higher and higher. The current development trend of automobile lightweight makes the structure of automobile body change, such as thinning of outer panels, hollowing of structural parts, etc. This phenomenon will affect the NVH performance of automobiles. And its potential safety hazard will cause injury to the occupant. In order to solve this method of using thin steel plate as the body material to reduce the weight of the body in order to achieve the purpose of energy saving and consumptio...
