Problems solved by technology

In this invention patent, odor inhibitors are used to reduce the odor of materials, which can prevent the emission of materials, but this method only plays an adsorption role, and the odor and small molecule materials are still inside the material, and the material will be lost in the process of later use. Slow release, unable to fundamentally solve the problem of odor and VOC

Abstract

The invention discloses an ultralow-emission glass-fiber-reinforced polypropylene composite material and a preparation method thereof. The material comprises the following components in percentage by weight: 51.2-93.2% of polypropylene, 5.0-40.0% of glass fiber, 1.0-5.0% of compatilizer, 0.5-2.0% of volatilization assistant, 0.1-0.5% of antioxidant, 0.1-0.3% of photostabilizer and 0.1-1.0% of lubricant. The preparation method comprises the following steps: mixing the components in a high-speed mixer, and carrying out extrusion granulation under dual vacuum conditions by using a double screw extruder to obtain the ultralow-emission glass-fiber-reinforced polypropylene composite material. The ultralow-emission glass-fiber-reinforced polypropylene composite material has extremely low smell, and completely satisfies the requirements of the automobile host plant for smell; the TVOC (total volatile organic compound) content is much lower than the host plant standard; and the composite material has the same properties as the existing material, and thus, can be completely substituted for the existing material.

Description

Technical field [0001] The invention relates to a glass fiber reinforced polypropylene composite material, in particular to an ultra-low emission glass fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, people stay in the car for longer and longer, and the air quality in the car will affect people's health to a greater extent. The official implementation of the first national standard for air quality in cars, "Guidelines for the Evaluation of Air Quality in Passenger Cars", GB / T 27630, has also pushed back to the research focus on how to improve the air quality in cars. Studies have found that the degree of air pollution inside the car is sometimes 10 times higher than that outside the car. The main source of polluted air in the car compartment is the VOC emissions of interior materials, free formaldehyde, alkanes, benzene, toluene, xylene, aldehydes and other vo...
