Problems solved by technology

However, these chemical substances can cause damage to the human nervous system, immune system, endocrine system, etc., and may cause cancer in severe cases.
[0003] At present, methods commonly used in the domestic market to reduce VOC in materials include fixed adsorption, cover-up, chemical deodorization, etc., but VOC will still remain in the material in these ways, which cannot be ruled out.
In order to reduce the VOC in the material, some suppliers adopt the method of high temperature baking for devolatilization treatment, but this method will reduce the performance of the material
At present, several large modification plants in China adopt the method of devolatilization with inert gas, but this method has relatively high requirements for equipment and complicated process

Abstract

The invention provides a glass fiber reinforcement PP material with low VOC and a preparation method of the glass fiber reinforcement PP material. A pp material is adopted as a base material, by adding extracting agent master batch, on the premise of not changing equipment, VOC is removed from the interior of the material rather than being absorbed by a porous material or remaining in the material by virtue of the blocking of a deodorizing agent, and the method has good effect for reducing the VOC; moreover, the complexity of the processing technology is not increased; less extracting agent master batch is used, and by adding 1.5 to 3.5 parts by weight of extracting agent master batch, the requirement of people on PV3900 and PV3341 can be met; by adding a grafting agent, an antioxidant and glass fibers, mechanical properties of the PP material are improved, the tensile strength is 94MPa or higher, the elongation at break is 3.1 percent or higher, the bending modulus is 7800MPa or higher, a melt index is 3.4 g / 10min or higher, and the impact strength is 10.5KJ / m<2> or higher.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a low-VOC glass fiber reinforced PP material and a preparation method thereof. Background technique [0002] VOC is the English abbreviation of volatile organic compounds (volatile organic compounds) at room temperature, such as trichloroethylene, tetrachloroethylene, formaldehyde, toluene, benzene, xylene, etc., and other substances such as ethanol and ketones. These chemical substances have the characteristics of being volatile (easy to dry) and lipophilic (easy to remove oil stains). Taking advantage of these characteristics, they are widely used as solvents or cleaning agents for coatings, adhesives, etc. in the industry. However, these chemical substances can cause damage to the human nervous system, immune system, endocrine system, etc., and may even cause cancer in severe cases. [0003] At present, the methods commonly used in the domestic market to reduce VOC in...
