Abstract

The invention relates to the technical field of automobile tailboards, and particularly relates to an acid-proof automobile tailboard material. The acid-proof automobile tailboard material comprises the following components by mass: 50-75 parts of polylactic acid, 30-45 parts of short carbon fiber, 15-22 parts of hydroxymethyl cellulose, 8-15 parts of polybutylene terephthalate, 2.6-4.5 parts of polyolefin elastomer, 25-40 parts of polycarbonate, 1.8-3.2 parts of bamboo fiber, and 4-10 parts of an acid-proof penetrant. After the formula is adopted, the acid-proof automobile tailboard material greatly improves the acid resistance, eliminates the deformation of the tailboard, improves the use attractiveness of the tailboard, prolongs the service life, and meets the high-quality requirement of automobiles; in addition, the acid-proof automobile tailboard material is convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of automobile tailgates, in particular to an acid-resistant automobile tailgate material. Background technique [0002] With the development of the automobile industry, the use of automobiles is increasing year by year. However, in actual use, the tailgate of a car is exposed to the air for a long time and is eroded by the acidity of rainwater, resulting in deformation of the tailgate and a reduction in life, which brings short-term replacement costs to car users and directly affects the long-term use and consumption of car users. . Therefore, it is a high-quality requirement for the development of automobiles to require good acid resistance for the tailgate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an acid-resistant automobile tailgate material. [0004] In order to solve the above-mentioned technical problems, an acid-resistant automo...
