Embodiment Construction

[0022] A PP material used for car child seats comprises the following components by weight.

[0023] The PP material component (unit: parts by weight) described in the embodiment of table 1

[0024]

[0025]

[0026] Preferably, the PP toughening agent is ExxonMobil 6102PP toughening agent. ExxonMobil 6102PP toughening agent is a POE high-efficiency toughening agent produced by ExxonMobil Corporation. It has a significant toughening effect on PP materials and makes PP materials have better toughness performance at high and low temperatures.

[0027] Preferably, the antioxidant is a mixture of monophenylenedioctyl phosphite and antioxidant PNX 103. Phenyl diisooctyl phosphite is used as an antioxidant for polymers, which is excellent in reducing the yellowing of plastics. The antioxidant PNX 103 is a domestic high-efficiency antioxidant, and its stabilizing effect is several times higher than that of traditional 1010 antioxidants. The combined effect enhances the compre...

Abstract

The invention discloses a PP material for an infant car seat. The PP material comprises the following raw materials in parts by weight: 80-90 parts of PP, 1-3 parts of maleic anhydride grafted polyethylene, 5-8 parts of ethylene propylene terpolymer, 5-15 parts of PP flexibilizer and 0.2-1 part of an antioxidant. Through various additive components in the PP material, the overall performance of the PP material is greatly strengthened, and the strength, the hardness, the rigidity, the heat resistance and the processability are improved. The injection molding process of the PP material is high in operability and reasonable in step design, and implementation of the yield of a product and the performance of the PP material is ensured. The PP material is simple and reasonable in formula and excellent in performance, the defects are overcome on the basis of reserving the advantages of the PP material, and the infant car seat of the PP material has good mechanical property, adequate safety and long service life.

Description

technical field [0001] The invention relates to a plastic, especially a PP material used for a car child seat. Background technique [0002] Child seats have been widely used in developed countries in Europe and America, and these countries have basically formulated quite strict regulations to guide and standardize their production and use. With the rapid increase of car ownership, although people have adopted various advanced technologies and measures, the current child casualties caused by traffic accidents are far higher than the accidental injuries caused to children by any other reason. Therefore, the correct use of child safety seats is one of the methods that can effectively prevent accidental injuries of children caused by traffic accidents, and the related child safety seat technology has also become the development direction of the industry. [0003] The development of child seats can be started from two aspects of structure and technology. In terms of structure, ...
