Problems solved by technology

However, reducing VOC by controlling the source of raw materials only solves one factor of VOC generation, and cannot solve the newly generated VOC substances in the process
The adsorption method, whether it is physical adsorption or chemical adsorption, has the problem of selectivity and balance of adsorption.
Chinese patent CN105001525A by adding at least one of activated carbon, molecular sieve, zeolite powder and nano inorganic powder (TiO 2 or ZnO) to reduce odor and VOC, the former is mainly used for adsorption, and the latter is mainly used for adsorption and degradation of VOC, but the 20-80nm nano-inorganic powder is easy to agglomerate, and its ability to absorb and degrade is greatly reduced. And without modification, it needs to be excited by ultraviolet light to play a role, so the effect is very limited
However, the low-molecular organic repellant used in this method has compatibility problems with the polypropylene resin and the carbonates and their decomposition products, and water and fatty alcohols with a boiling point lower than 200°C, due to their low boiling point and And the premix is ​​added to the extruder in the main feed, then there are problems with the durability and uniformity of the melt of the modified polypropylene material
The above invention only improves a certain factor that generates VOC, and cannot solve the problem of VOC generated in both raw materials and production processes at the same time

Abstract

The invention discloses a low-VOC glass fiber reinforced polypropylene burning-slowing composite material and application. The composite material comprises, by weight, 35-75 parts of polypropylene, 4.5-6 parts of hollow glass microbeads, 15-45 parts of glass fiber, 0-4 parts of talcum powder, 0.1-0.5 part of an antioxidant, 0.3-0.5 part of an anti-ultraviolet auxiliary, 1-3 parts of a compatilizer, 1-2 parts of an efficient burning slowing agent and 3-4 parts of an VOC inhibitor. The composite material can catalytically degrade VOC in a vehicle in an efficient, energy-saving and environment-friendly manner without the help of an ultraviolet source or equipment outside; the hollow glass microbeads coated with the compatilizer on the surface are added, so that strength of the composite material is not lowered while the composite material is high in compatibility with glass fiber reinforced PP, and density can be effectively lowered; a small amount of the efficient burning slowing agent is added, so that flame retardance of the composite material is improved. The low-VOC glass fiber reinforced polypropylene burning-slowing composite material can be applied in vehicles and household appliances.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low-VOC glass fiber reinforced polypropylene slow-burning composite material and its application. Background technique [0002] With the rapid development of social economy, cars have become indispensable in people's lives. Since modern people stay in the car for a long time every day, the air quality inside the car is closely related to human health. There are two main factors that affect the air quality in the car: one is the release of harmful gases from the interior of the car itself; the other is the release of harmful gases from the car decorations selected by the car owner. In the final analysis, these two aspects are the volatilization of harmful gases in automobile interior decoration parts. The harmful gases are mainly volatile organic compounds (volatile organic compounds), that is, VOC. WHO defines VOC as volatile compounds with a boiling point between ...
