Problems solved by technology

[0002] With the improvement of the quality of life, consumers have higher and higher requirements for the quality of car interiors, accessories and household appliances. Taking the dashboard of car interior parts as an example, hard dashboards are often used in economical models or tough SUVs. , that is, PP injection molding. This material has a strong sense of plastic and cannot give people a soft texture. It often cannot satisfy the warm and luxurious decoration style. In order to achieve this soft touch effect, the existing technology also uses highly elastic paint to Realized, but this method will increase the cost and cause great pollution to the environment

The above components are all calculated by mass percentage, the polypropylene is homopolypropylene, the melt flow rate of the polypropylene is 0.1-50g / 10min, the test condition is 2.16kg / 230°C, the crystallinity of homopolypropylene Above 80%, the isotacticity is 90%, the viscosity of the amino polyether block silicone oil is 4000mPa·s, and the additives are antioxidant 264 and a halogen-free flame retardant.

Embodiment 3

[0021] Add 70% polypropylene, 2% calcium pimelate nucleating agent, 8% K resin, 17% amino polyether block silicone oil and 3% additives into a high-speed mixer and mix for 3-5Min at a speed of 1000-2000 rpm. The premix is ​​obtained, and the premix is ​​added to the sample of the twin-screw extruder, and the temperature of each zone of the screw is 180-220°C. The above components are all calculated by mass percentage, the polypropylene is homopolypropylene, the melt flow rate of the polypropylene is 0.1-50g / 10min, the test condition is 2.16kg / 230°C, the crystallinity of homopolypropylene Above 80%, the isotacticity is 95%, the viscosity of the amino polyether block silicone oil is 3000mPa·s, and the additives are antioxidant 1076, halogen-free flame retardant and hindered amine stabilizer.

Abstract

The invention discloses a low-gloss polypropylene composition, which is composed of the following components in mass percentage: 50-75% of polypropylene, 1-5% of nucleating agent, 5-20% of K resin, and 10-10% of organic silicon material 20%, auxiliary agent 1-5%, described polypropylene is homopolypropylene, and described polypropylene melt flow rate is 0.1-50g / 10min, and test condition is 2.16kg / 230 ℃; The crystallization of homopolypropylene The degree is above 80%, and the isotacticity is 90-95%. The silicone material is amino polyether block silicone oil. The product obtained by using the composition of the invention has a softer touch, and the surface gloss of the product is low, and can achieve a warm and luxurious decorative feeling both visually and tactilely.

technical field [0001] The invention relates to the technical field of new materials, in particular to a low-gloss polypropylene composition. Background technique [0002] With the improvement of the quality of life, consumers have higher and higher requirements for the quality of car interiors, accessories and household appliances. Taking the dashboard of car interior parts as an example, hard dashboards are often used in economical models or tough SUVs. , that is, PP injection molding. This material has a strong sense of plastic and cannot give people a soft texture. It often cannot satisfy the warm and luxurious decoration style. In order to achieve this soft touch effect, the existing technology also uses highly elastic paint to Realized, but this method will increase the cost and cause great pollution to the environment. [0003] "Soft touch" is a property of plastic parts, which is divided into two aspects: visual touch and hand touch. It can be described as the soft...
