Problems solved by technology

However, this kind of reinforcing film has at least the following disadvantages: the production environment of domestic automobile manufacturers is complex, and the construction temperature of many manufacturers is lower than 15°C. Insufficient, there are still problems such as difficult construction and falling off of reinforcing film in autumn and winter
This kind of reinforcing film also has the problem of poorer adhesion to oil-coated steel plates at temperatures below 15°C

Embodiment 1

[0021] This embodiment provides a reinforcing film suitable for construction on oily steel plates at low temperatures. The reinforcing film is composed of glass fiber substrates, adhesive layers A and B, and the adhesive layer A is bonded to connected between the glass fiber substrate and the bonding layer B;

[0022] The glass fiber base material of the above-mentioned reinforcing film is used as the skeleton layer of the reinforcing film, and a commercially available thickness of 0.14 to 0.2 mm is an alkali-free glass fiber base material;

[0023] The bonding layer A of the above-mentioned reinforcing film is made up of epoxy resin, epoxy resin curing agent, nitrile rubber, rubber vulcanizing agent, plasticizer and filler, and each raw material consumption of bonding layer A is calculated as: Oxygen resin 20-50%, epoxy resin curing agent 2-5%, nitrile rubber 15-30%, rubber vulcanizing agent 0.5-3%, plasticizer 1-30% and filler 5-40%.

[0024] Among the various raw materials...

Embodiment 2

[0055] This embodiment provides a reinforcing film suitable for construction on oily steel plates at low temperatures, which is suitable for construction on oily steel plates at low temperatures. The preparation method of the reinforcing film is as follows:

[0056] Preparation of adhesive layer A: Add 20 parts of solid nitrile rubber NBR2707 into the open rubber mixer for 2 to 4 minutes to masticate, then add 25 parts of epoxy resin E-51, 20 parts of dioctyl adipate, and 20 parts of heavy calcium 11.5 parts of nano-modified calcium carbonate, 1.5 parts of dicyandiamide, and 1 part of dicumyl peroxide. After mixing for 10 to 15 minutes, thin pass 3 to 5 times, lower the roll, and use a rubber extruder to extrude Form the adhesive layer A film with a width of 300mm, a thickness of 1mm, and a length of 1m for use;

[0057] Preparation of adhesive layer B: Add 17.5 parts of styrene-butadiene rubber SBR1502 to the open rubber mixer for 2 to 4 minutes of mastication, and then add 1...

Embodiment 3

[0060] This embodiment provides the raw materials and preparation method of the adhesive layer A in the reinforced film as in Example 2; the raw material of the adhesive layer B replaces styrene-butadiene rubber SBR1502 with butadiene rubber BR9000, and its preparation method is the same as in Example 2.

[0061] The reinforcing film made by the above-mentioned embodiment is compared with the currently commonly used reinforcing film, specifically as follows:

[0062] The reinforcing film used for comparison adopts the currently commonly used reinforcing film (hereinafter referred to as the contrasting reinforcing film A), and its adhesive layer is one layer. The main feature of the adhesive layer is that it contains epoxy resin and acrylonitrile group. of nitrile rubber.

Abstract

The invention discloses a reinforced rubber sheet that is suitable for construction on steel plate with oil surface at a low temperature, and preparation method thereof. The reinforced rubber sheet is composed of fiberglass substrate, a bonding layer A and a bonding layer B, wherein the bonding layer A is bonded between the fiberglass substrate and the bonding layer B; the bonding layer A is composed of epoxy resin, an epoxy resin curing agent, acrylonitrile butadiene, a rubber vulcanizing agent, a plasticizer, and filling material. The reinforced rubber sheet possesses simple production process and strong regional adaptability, is suitable for construction on steel plate with oil surface at a low temperature, has good adhering effect, and can avoid operations of heating the reinforced rubber sheet with a baking oven, removing oil on the region where the reinforced rubber sheet is to be bonded, heating etc. that generally exist in present automobile manufacturers in low temperature seasons such as autumn and winter, and thus energy is effectively saved and production efficiency is enhanced.

Description

technical field [0001] The invention relates to a film for reinforcing thin steel plates of automobile bodies, in particular to a reinforcing film suitable for construction on oil surface steel plates at low temperature and a preparation method thereof. Background technique [0002] With the increasing emphasis on energy saving and environmental protection, the development of modern automobiles has been actively developing in the direction of light weight, energy saving, safety, environmental protection and comfort. It is one of the best ways to save energy and reduce pollution by reducing the thickness of the body steel plate material, making the outer plate thin-walled, and hollowing out the structural parts to reduce the weight of the car. However, the thinning of the steel plate will bring some negative effects: the partial rigidity of the body will decrease, the door, roof, side wall and other parts will easily vibrate during the driving process of the car, resulting in...
