Problems solved by technology

Most of the anti-stone chip coatings currently used are PVC coatings, which are inconvenient to use. After spraying on the chassis of the car, they need to be baked at 140°C for more than 30 minutes, but ordinary car maintenance shops and users do not have such baking conditions, so , the "popularization" of traditional anti-stone chip coatings is a difficult problem

Abstract

The invention discloses a normal-temperature stone-impact-resistant paint and a preparation method thereof. The paint contains 1-3% of thermoplastic elastomer SBS (styrene-butadiene-styrene), 9-15% of asphalt, 13-21% of tackifying resin, 2-4% of accelerator, 0.5-1% of thickener, 25-40% of filler and 30-40% of solvent. The preparation method comprises the following steps: immersing the SBS, asphalt and tackifying resin in the solvent for 1-2 days; adding the filler, accelerator and thickener, and milling uniformly; putting the colloid in a mixing machine, adding a small amount of solvent, and stirring uniformly; and filtering through a filter screen, and filling. The paint has favorable adhesive force for automobiles; and the test proves that the paint can not deform, shed, crack or blister at -40-80 DEG C. The coating can not lose efficacy after being immersed in water for more than 1 month. The cured paint can effectively resist the impact of roadway stones on the automobile chassis, and has the effects of sound insulation and corrosion resistance, thereby prolonging the service life of the automobile and providing an easeful and comfortable driving environment for people.

Description

technical field [0001] The invention relates to a paint for car antirust care, in particular to a normal temperature anti-stone chip paint and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the automobile market, people's demand for automobiles has gradually increased, which has also led to the development of the automobile maintenance and care market. How to maintain your car is a topic that people are keen to discuss nowadays. At present, the coating for automobile antirust care is a new product of automobile antirust care in recent years. The general method is to spray a layer of 2-4mm thick elastic sealing material under the chassis of the car, just like putting a thick layer of armor on the chassis of the car. Most of the anti-stone chip coatings currently used are PVC coatings, which are inconvenient to use. After spraying on the chassis of the car, they need to be baked at 140°C for more than 30 minutes...
