Embodiment 1～3

[0033] Embodiment 1~3, its preparation method comprises the steps:

[0034] According to Table 1, PA6 (M2800), ABS (757K), PMMA (CM-211), compatibilizer (SMA-700), antioxidant (1010 / 168=1:2) and lubricant ( E525) into the high-speed mixer, mix for 1 to 2 minutes, and then weigh toughening agent 1 (HR-181), toughening agent 2 (EXL-2678), toughening agent 3 (KT-915) and resistant Add the scraping agent (GM100A) to the above-mentioned uniformly mixed material, mix for 1-2 minutes, and finally add the uniformly mixed material to the hopper of the twin-screw extruder to melt and extrude it. The temperature of each section of the twin-screw extruder is: 1 The temperature in zone 2 is 100°C; the temperature in zone 2 is 230°C; the temperature in zone 3 is 225°C; the temperature in zone 4 is 210°C; the temperature in zone 5 is 220°C; 38rpm / min, the products produced in Examples 1-3 are denoted as B1-B3 respectively.

Embodiment 4

[0035] Embodiment 4, its preparation method comprises the steps:

[0036] First, weigh PA6 (M2800), PA66 (EP158), ABS (757K), PMMA (CM-211), compatibilizer (SMA-700), antioxidant (1010 / 168=1:2) according to Table 1 ) and lubricant (E525) were added to the high-speed mixer, mixed for 1 to 2 minutes, and then the weighed toughening agent 1 (HR-181), toughening agent 2 (EXL-2678), toughening agent 3 (KT -915) and anti-scratch agent (GM100A) are added to the above uniformly mixed material, mixed for 1-2 minutes, and finally the mixed material is added to the hopper of the twin-screw extruder to melt and extrude, each of the twin-screw extruder The temperature of the section is: the temperature of zone 1 is 100°C; the temperature of zone 2 is 260°C; the temperature of zone 3 is 255°C; the temperature of zone 4 is 240°C; the temperature of zone 5 is 250°C; The screw speed of machine is 38rpm / min, and the product that embodiment 4 produces is denoted as B4.

Embodiment 1

[0037] The lubricant of embodiment 1 is stearic acid;

Abstract

The invention discloses a scratch-resistant and high-impact matte oil-resistant and weather-proof ABS-PA-PMMA alloy material and a preparation method thereof. According to key points of the technicalscheme, the scratch-resistant and high-impact matte oil-resistant and weather-proof ABS-PA-PMMA alloy material comprises the following components in percentage by weight: 25-50% of PA, 10-35% of ABS,10-20% of PMMA, 3-8% of a compatilizer, 10-20% of a compound toughening agent, 3-5% of a scratch-resistant agent, 0.2-0.5% of an antioxidant and 0.4-0.7% of a lubricant. The scratch-resistant and high-impact matte oil-resistant and weather-proof ABS-PA-PMMA alloy material disclosed by the invention has good scratch resistance, good toughness, excellent matte effect, better dimensional stability, good oil resistance and good weather resistance.

Description

【Technical field】 [0001] The invention relates to the technical field of polymers, in particular to a scratch-resistant, high-impact matte oil-resistant and weather-resistant ABS-PA-PMMA alloy material and a preparation method thereof. 【Background technique】 [0002] Polyamide (PA) has excellent wear resistance, self-lubrication, corrosion resistance and processability, but it has high water absorption, poor dimensional stability and low impact. Acrylonitrile-butadiene-styrene copolymer (abbreviated as ABS) has good toughness, good chemical resistance, excellent dimensional stability, good processing formability and excellent colorability, etc., but its weather resistance is poor . Polymethyl methacrylate (PMMA for short) has high surface hardness and excellent weather resistance, but its molecular chain contains ester groups, has a large water absorption rate, and has obvious creep at room temperature, and its melt viscosity is relatively low. High rigidity, prone to stre...
