Description
Technical Field
The utility model relates to an automobile-used film field especially relates to a compound film of damping reinforcement for automobile steel sheet.
Background
In order to reinforce a vehicle body and improve the safety of an automobile, a weak portion of a vehicle body steel plate needs to be reinforced. At present, the automobile reinforcing rubber sheet is generally adhered to a steel plate to form a composite material with the steel plate, so that the purpose of reinforcing the steel plate is achieved.
The automobile reinforcing film is generally a double-layer structure, for example, the utility model patent with publication number CN203142580U and publication date 2013.8.21 provides a reinforcing film and an automobile using the same, the reinforcing film in the patent comprises a structural layer and a bonding layer, wherein the structural layer is a glass fiber framework layer, which is a main part for playing the function of the reinforcing film, the structural layer is a glass fiber framework layer, the bonding layer is an epoxy resin/rubber layer and is used for bonding with an attached object, so that when the reinforcing film is adhered to a weak part of a steel plate, the reinforcing effect can be achieved, and when the bonding layer is made of damping materials such as rubber, vibration energy can be converted into thermal energy to be dissipated, and the effects of shock absorption and noise reduction are achieved. The reinforcement film can meet the requirements of reinforcement and noise reduction at the same time, but the current reinforcement film still has the following two problems: firstly, the reinforcing rubber sheet can be firmly adhered to the steel plate after being heated and plasticized, but the toughness of the rubber sheet is poor, heat during heating and plasticizing is accumulated on one side where the rubber sheet is adhered to the steel plate, and the rubber sheet shrinks greatly after being solidified, so that the steel plate is easy to deform; secondly, when a film with a large using area is adhered, gas is easily left on the side where the film is adhered to the steel plate to form bubbles, so that the film is not tightly adhered to the steel plate, the adhesion strength is influenced, and the thin steel plate is easily deformed; and thirdly, the viscosity of the film can be reduced under a low-temperature environment (such as winter) and the film is easy to fall off.
How to solve the above problems is a technical problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can reduce the steel sheet and warp, adhesive strength is high, be difficult to the compound film of damping reinforcement for the automobile steel sheet that drops.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a pair of compound film of damping reinforcement for automobile steel sheet, including the film body, the film body includes and is provided with a plurality of incisions that run through film body both sides on magnetic damping layer and this film body.
Further, the film body still includes restraint layer, reinforcement glue film, magnetism damping layer top-down overlap the setting in proper order.
Furthermore, the incisions are of a linear structure which sequentially penetrates through the constraint layer, the reinforcing adhesive layer and the magnetic damping layer from top to bottom, the lengths of the incisions are equal, and the incisions are distributed on the film body in a rectangular array.
Furthermore, a plurality of sawteeth arranged along the edge of the film body are arranged on the periphery of the film body.
Furthermore, each sawtooth is an isosceles trapezoid structure.
Furthermore, the restraint layer is made of glass fiber cloth or aluminum foil materials.
Since the structure is adopted, the utility model discloses beneficial effect who has as follows:
the utility model arranges a plurality of notches on the film body, when the film body is heated, plasticized and pasted on the steel plate, the heat and gas can be discharged through the notches, thereby the film body and the steel plate are more closely pasted, and the deformation of the steel plate can be reduced; and the film body comprises a magnetic damping layer, and the magnetic damping layer attracts the steel plate through the magnetic action, so that the film body is effectively prevented from falling off due to the viscosity reduction under the low-temperature environment.
The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings which illustrate embodiments of the invention.
