Automotive mildew-proof flame-retardant smoke-suppression PVC (polyvinyl chloride) low-foam crust lining plate and preparation method thereof

Abstract

The invention provides an automotive mildew-proof flame-retardant smoke-suppression PVC (polyvinyl chloride) low-foam crust lining plate. The plate is prepared from, by weight, 100 parts of PVC, 3-6 parts of a heat stabilizer, 0.5-3.2 parts of a lubricant, 6-15 parts of a processing aid, 0.5-1 part of a foaming agent, 0.5-1.2 parts of an antibacterial mildew-proof agent, 29-120 parts of a flame retardant, 5-50 parts of a filler agent and 0.4-3 parts of a plasticizer. The antibacterial mildew-proof agent is prepared from, by weight, 12%-15% of organic cation antibacterial functional groups, 3%-5% of antibacterial metallic elements and 80-85% of lamellar clay. The raw materials are subjected to compounding, high-speed mixing, low-speed mixing, extruding in a double-screw extruder, molding, cooling forming and cutting to prepare the automotive mildew-proof flame-retardant smoke-suppression PVC low-foam crust lining plate, efficient and durable broad-spectrum antibacterial effects of the antibacterial mildew-proof agent are achieved, low toxicity and high heat resistance are realized, a safe environment can be created for people in use of automobiles, and the compound flame retardant has great flame retardation effects while mechanical performances can be guaranteed.

Description

technical field [0001] The invention relates to a plastic board and its technology, in particular to a mildew-proof, flame-retardant, smoke-suppressing PVC low-foaming crust lining board for automobiles and a preparation method thereof. Background technique [0002] Automotive interior panels generally refer to the partitions, door linings, instrument panel assemblies, and other parts of the car compartment. They are usually required to have the characteristics of beauty, softness, comfort, warmth, good elasticity, and no odor. Generally, the preparation method of the automotive interior composite board includes heating and baking, melt extrusion, and pressing by molding equipment. At present, automobiles are prone to natural phenomena in a long-term high-temperature working environment, which greatly increases the probability of accidents. Manufacturers generally foam the polymer matrix to achieve heat preservation and sound insulation effects, and dope inorganic flame reta...

AI Technical Summary

Problems solved by technology

At present, automobiles are prone to natural phenomena in a long-term high-temperature working environment, which greatly increases the probability of accidents. Manufacturers generally foam the polymer matrix to achieve heat preservation and sound insulation effects, and dope inorganic flame retardants to achieve flame retardant effects.

The doped inorganic flame retardant is prone to discoloration under long-term use, and it is not easy to mix with the substrate evenly during processing, which will affect the mechanical properties of the interior panel and pose a threat to the processing and use of the interior panel; in addition Automobile inner lining boards made of traditional materials do not have the effect of sterilization and anti-mildew. Automobiles used in humid and rainy environments for a long time are prone to mildew inside, which affects the user experience of the car.
