Embodiment 1

[0032] 20Kg ASA rubber powder 1, 20Kg ASA rubber powder 2, 55Kg AS resin, 5Kg graft copolymer of silicone rubber and AS, 1Kg EBS, 0.5Kg silicone oil, 0.5Kg PE wax, 0.5Kg zinc stearate, 0.2Kg bismuth Phenol A, 0.2Kg IG-168, 0.2Kg IG-245, 0.3Kg IG-770DF were added to a high-speed mixer and stirred for 20 minutes before being discharged, and then extruded in a twin-screw extruder with an aspect ratio of 36 and a diameter of 35mm For medium extrusion granulation, the barrel temperature of the extruder is 180-240°C, and the screw speed is 180-600rpm.

Embodiment 2

[0034] The purpose of this example is to compare the influence of different surface gloss agent dosages on product performance.

[0035] Select the same graft copolymer copolymer of silicone rubber and AS as the surface gloss agent for use in Example 1, and the addition amount is correspondingly changed into 20 parts from 5 parts in Example 1, and specifically made as follows: 20Kg ASA rubber powder 1, 20Kg ASA rubber powder 2, 40Kg AS resin, 20Kg graft copolymer of silicone rubber and AS, 1Kg EBS, 0.5Kg silicone oil, 0.5Kg PE wax, 0.5Kg zinc stearate, 0.2Kg bisphenol A, 0.2Kg IG- 168, 0.2Kg IG-245, 0.3Kg IG-770DF, put into a high-speed mixer and stir for 20 minutes before discharging, then extrude and granulate in a twin-screw extruder with an aspect ratio of 36 and a diameter of 35mm. The barrel temperature of the machine is 180-280°C, and the screw speed is 180-600rpm.

Embodiment 3

[0037] The purpose of this example is to compare the effects of different amounts of ASA rubber powder.

[0038] The addition amount of ASA rubber powder is changed into 60 parts by 40 parts among the embodiment 1, specifically make as follows: the graft copolymerization of 30Kg ASA rubber powder 1, 30Kg ASA rubber powder 2, 35Kg AS resin, 5Kg silicone rubber and AS Material, 1Kg EBS, 0.5Kg silicone oil, 0.5Kg PE wax, 0.5Kg zinc stearate, 0.2Kg bisphenol A, 0.2Kg IG-168, 0.2Kg IG-245, 0.3Kg IG-770DF, add to the high-speed mixer Stir in medium for 20 minutes and discharge, then extrude and granulate in a twin-screw extruder with an aspect ratio of 36 and a diameter of 35mm. The barrel temperature of the extruder is 180-280°C, and the screw speed is 180-600rpm.

Abstract

The invention relates to a high-performance extrusion grade ASA resin composition and a preparation method thereof. The preparation method comprises the following steps of: selecting two ASA rubber powders which have high stainability and are composited with different molecular weight and different rubber particle sizes, high molecular weight AS resin, a surface glazing agent, matching with lubricating agent, antioxidant and a weather-proofing agent simultaneously, melting in a twin-screw extruder, blending and preparing the resin composition. The ASA resin composition has high toughness, weathering resistance and surface glossness and good processing performance and is especially applicable to combining extrusion of profiled materials used for buildings of PVC doors and windows and glazed tiles and the like.

Description

technical field [0001] The present invention relates to a high-performance extrusion-grade ASA resin composition and a preparation method thereof, in particular to a high-performance extrusion-grade ASA resin composition that can be used for PVC doors and windows or glazed tiles and other architectural profiled materials and its preparation method. technical background [0002] PVC plastic doors and windows have been widely popularized and applied in China because of their light weight, corrosion resistance, high strength, heat preservation, sealing and sound insulation, energy saving and environmental protection, easy processing and low cost. Due to the relatively unstable α-Cl in the molecular structure of PVC, the weather resistance of pure PVC processed materials is poor, and it is easily damaged by ultraviolet rays in sunlight outdoors, causing yellowing and redness and other discoloration phenomena. Rutile TiO 2 Has excellent light refraction effect, by adding a cert...
