Problems solved by technology

[0005] Among the modified plastic parts for automotive interiors, talcum powder, which has the largest filling amount of non-mineral powder, is undoubtedly one of the sources of odor testing; and because the talc masterbatch industry is rampant in the market at a high speed, it complies with the needs of market development , but during the processing of talc carrier masterbatch, the odor of talc masterbatch will be higher than that of talcum powder in comparison, which is equivalent to the filling application of masterbatch, after two banburying with resin, which will increase the odor of materials

Abstract

The invention discloses a low-odor functional talc master batch and a preparation method thereof. The low-odor functional talc master batch comprises the following raw materials (by weight): 78-80 parts of talc powder, 0.8-1 part of a coupling agent, 20-22 parts of a polypropylene monomer, 0.5-0.8 part of a lubricant and 0.2-0.5 part of an antioxidant. The raw materials are wide in source, the preparation process is simple, the prepared finished product is a rigid-tough balance type product after being filled, and the material shrinkage rate and the smell of the whole material can be reduced;the finished product is easy to process, the fluidity and demolding property of plastic processing are promoted to be improved, emission is reduced, and the volatilization amount of VOC is reduced without increasing the cost; the finished product has low atomization performance, the volatile matter content can be effectively reduced, the finished product has a synergistic effect with various flameretardants, the addition amount of the flame retardants can be properly reduced, the flame retardant requirement is met, and the application prospect is wide.

Description

technical field [0001] The invention relates to an automobile interior material, in particular to a low-odor functional talc masterbatch. Background technique [0002] With the continuous improvement of people's requirements for automobile quality, especially the continuous attention to the environmental protection requirements of automobiles, automobile interior parts have also put forward higher requirements for product odor levels. The development and application of low-odor automobile interior materials naturally become a A major trend in materials. The odor of automobile interior mainly comes from various leathers, plastics, fibers, etc. Among them, seats, ceilings, and dashboards are the most important sources of odors due to their large area and special location, and the VOCs (that is, volatile organic compounds) produced are also will cause harm. [0003] The hazards of VOC are: first, ozone generation: photochemical reaction with nitrogen oxides to generate ozone;...
