Description
Technical Field
The invention relates to a multifunctional memory type rearview mirror material.
Background
The rearview mirror is the second double eyes of a driver in the driving process of the automobile, is used as an auxiliary device for observing the road condition behind the automobile in the driving and reversing processes of the automobile and observing the surrounding conditions of the automobile by a driver in the driving process of the automobile, can be said to play a vital role for the driver, and can be widely used by people because the safety of people in driving the automobile can be improved. With the development of science and technology and the improvement of living standard of people, the number of automobiles is increased year by year, so that the driving and parking spaces of the automobiles are smaller and smaller, and the rearview mirror is difficult to avoid being rubbed and bumped. In addition, when the automobile runs in a rainy day, the rearview mirror is stained with rainwater and becomes fuzzy, so that the visibility is influenced, and the driving safety is reduced. In order to solve the problem, various rearview mirrors begin to appear, most of the rearview mirrors in domestic and foreign markets are structurally adjusted, although the damage of the rearview mirrors in collision can be reduced when the rearview mirrors are used, the rearview mirrors need to be adjusted when the rearview mirrors are prevented from collision, so that the rearview mirrors have blind areas, and certain safety problems are caused. The mirror housing is made of plastic resin, is easy to age after being used for a period of time, and has poor quality and can be damaged once being rubbed and bumped. Especially in cold winter in the north, the plastic resin can become brittle under low temperature weather conditions, which not only becomes difficult but also can damage the mirror housing during adjustment. In addition, although the rearview mirror shell cannot be damaged in the wiping process by adopting the common glass mirror, the glass rearview mirror still can be broken. Meanwhile, if the vehicle runs in rainy days, the common glass rearview mirror is stained with water drops to influence the view of the rearview mirror, and the safety is reduced.
Patent CN201720855137.4 discloses a novel rearview mirror, which can remind the driver when slightly rubbing by changing the structure of the rearview mirror and the connection mode of the main body, but the driver can not control the rearview mirror in time under the condition of rubbing, so the rearview mirror can be damaged. In addition, the novel car backing device removes rainwater by adding the resistance wire into the mirror shell, so that whether a fire disaster is possible or not is temporarily avoided, the process is more complicated by changing the structure, and the manufacturing cost is increased.
At present, the rearview mirrors on the market, whether sold or designed in research, are changed in terms of collision resistance, auxiliary mirrors are installed or radar prompting systems are added, and resistance wire heating, blowers, wipers and the like are mostly adopted in terms of rain prevention. While these designs may solve some problems, they not only increase manufacturing costs, but also introduce safety issues, such as the installation of a wiper may affect the surrounding view.
Therefore, the invention discloses a multifunctional memory type rearview mirror material, wherein the shell material is prepared from butadiene rubber and natural rubber. The natural rubber has higher strength, can meet the use requirement, and also has better elasticity and flexibility. The butadiene rubber can enable the elasticity, wear resistance, aging resistance and low temperature resistance of the product to be more excellent, and simultaneously reduce the cost of raw materials. Meanwhile, in order to prevent the common glass mirror from being broken due to collision and being blurred in rainy days, the glass lens material provided by the invention adopts the stainless steel lens to replace the traditional glass lens, and the multifunctional memory type rearview mirror made of the material solves the problems that the existing rearview mirror is easy to damage due to collision and is blurred in rainy days. In order to ensure that the rearview mirror not only has certain elasticity but also has certain strength, the rubber has elasticity and the strength meets the use requirement through the formula design.
Disclosure of Invention
The invention aims to provide a multifunctional memory type rearview mirror material which can prevent a rearview mirror from being damaged in collision and from being unclear in view in rainy days. In the invention, natural rubber and butadiene rubber are used as main raw materials in the aspect of integrating the performance of rubber and the cost of the raw materials. The addition of various compounding agents reduces the cost of the sizing material, enables the materials to be well connected together, and enhances the elasticity and strength of the backing mirror shell. The rubber is prepared by adding vulcanizing agent sulfur into the formula, so that rubber molecules can be connected with each other, the strength of the rubber is improved, the vulcanizing speed can be adjusted by controlling the sulfur dosage, and the phenomenon of sulfur shortage or sulfur spraying is prevented; in the reinforcing aspect, if the carbon black is simply added, the phenomenon of uneven dispersion can occur, so that the reinforcing effect is reduced, the montmorillonite not only has good dispersibility, but also can enhance the impact resistance and the dimensional stability of rubber, so that the compounding effect of the carbon black and the montmorillonite is better, the strength of the prepared backing mirror shell can meet the normal use, a metal framework is not required, the processing procedure is reduced, and the cost is saved; the montmorillonite contains magnesium oxide, aluminum oxide and silicon oxide, and the vulcanization time can be shortened by combining the montmorillonite with stearic acid; in order to enable the backing mirror shell to have better elasticity, a trace amount of foaming agent can be added, so that micro bubbles in a product achieve a better elastic effect when the performance is not influenced, and at the moment, calcium bicarbonate can be added to serve as the foaming agent, so that the foaming agent is harmless and environment-friendly; adding silane coupling agent KH550 modified montmorillonite to improve filler dispersibility and product performance; the anti-aging effect of the product can be better and the service life of the rearview mirror shell can be prolonged by adding the anti-aging agent D and the antioxidant. The multifunctional memory type rearview mirror shell material prepared by the invention has better elasticity and strength, and has certain memory and can quickly return to the original shape after collision. The stainless steel rearview mirror is mounted on the rearview mirror shell, so that the problem of collision is solved, and the problem of blurred vision in rainy days is also solved. The raw materials used in the invention can be purchased at home, are more economical and are convenient for mass production of the rearview mirror shell.
The technical scheme adopted by the invention is as follows:
the multifunctional memory type rearview mirror material comprises a rearview mirror shell raw material which is composed of 60 parts of natural rubber, 40 parts of butadiene rubber and 50.5 parts of a compounding agent according to a mass ratio.
