Problems solved by technology

However, the design and transformation of the material itself, so as to reduce or alleviate the car noise pollution at the root, is quite scarce. The effect of noise reduction can be obtained by adding hollow inorganic fillers, but the disadvantage is that it will affect the processability of the material and affect the molding of the product.

preparation example Construction

[0032] The preparation method of anti-noise master batch comprises the following steps:

[0033] After preparing materials according to the formula, the carrier resin, foaming agent, and foaming aid are stirred and mixed in a high-speed mixer, and then sent into a twin-screw extruder through a metering device. , The material is melted and compounded, and then through the steps of extrusion, drawing, cooling and pelletizing, the anti-noise masterbatch is obtained. Wherein the screw length-to-diameter ratio of the twin-screw extruder is 36-44, and is equipped with a temperature control device and a vacuum device; the extrusion temperature of the twin-screw extruder is between 200-260°C, and the screw speed is 200-500 rpm.

[0034] The light stabilizer is one or more mixtures of salicylic acid esters, benzophenones, triazines, benzotriazoles UV absorbers and hindered amine free radical scavengers. Other additives are selected from silane coupling agent, titanate coupling agent,...

Abstract

The invention relates to an anti-noise heat-resistant ABS resin composition and a preparation method thereof. The composition includes the following raw materials, by weight: 100 parts of acrylonitrile-butadiene-styrene (ABS) resin, 5-20 parts of a heat-resistant agent, 5-20 parts of an anti-noise master batch, 0.5-1.0 part of a photo-stabilizer, and 0.5-1.5 parts of other processing additives. The preparation method includes the steps of: stirring the raw materials in a high-speed mixer to fully mix the raw materials, feeding the mixture into a double-screw extruder through a metering device to melt and composite the raw materials through transportation, shear and mixing by means of screw rods, and performing extrusion, bar drawing, cooling and granule cutting to prepare the anti-noise heat-resistant ABS resin composition. The preparation method is simple. The anti-noise heat-resistant ABS resin composition is excellent in anti-noise effect and mechanical performance, and is very suitable for being used in the field of automobile interior.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to an anti-noise and heat-resistant ABS resin composition and a preparation method thereof. Background technique [0002] The rapid development of automobiles has brought great convenience to human life, but it is also accompanied by inevitable noise pollution. The noise in the car is mainly the noise of various parts of the car outside the car through the transmission into the car interior and the noise generated by the vibration of the car interior parts. The main sources include engine noise, body resonance noise, chassis noise, wind noise, and resonance noise in the box. Wait. Excessive noise in the car will directly affect the driving environment of the driver and passengers, including physical and psychological effects, and even affect safe driving. Therefore, the size of the noise produced by the car reflects the design and manufacturing level of the car...
