    摘要: The present disclosure provides an ultralow-glossiness, ultralow-temperature resistant ASA resin composition and preparation method thereof. The composition includes the following components in parts by weight: 20˜60 parts of an acrylonitrile-styrene-acrylate graft copolymer, 40˜80 parts of an acrylonitrile-styrene copolymer, 1˜20 parts of an ultralow-glossiness, low temperature resistant modifier, and 0.1˜5 parts of a processing aid. The ultralow-glossiness, low temperature resistant modifier includes a carrier copolymer, a fluorinated copolymer, a low-temperature flexibilizer, a coupling agent, fumed silica and an assistant. The ASA resin composition prepared by the present disclosure has an ultralow-glossiness, can be used to replace mold processing technology such leather marking and texturing, which greatly saves mold cost and processing production cost; and meanwhile it also has excellent low temperature resistance and can be applied in cases having requirements on low temperature resistance and low glossiness such as automobile parts, outdoor profiles, building materials and electrical appliances.

    摘要: The present disclosure provides a polyester composition suitable for ultrasonic welding and preparation method thereof, the composition includes the following components in parts by weight: 30˜50 parts of poly(1,4-cyclohexylene dimethylene terephthalate), 40˜60 parts of ABS, 5˜10 parts of a melt enhancer, 0.1˜1 parts of an antioxidant, and 0.1˜1 parts of a lubricant. Compared with the existing technologies, the polyester composition provided by the present disclosure improves melt strength by using the melt enhancer. The melt enhancer used is an ultra-high density polyethylene resin having a glycidyl methacrylate group after an irradiation treatment, so that the compatibility of the melt enhancer to the poly(1,4-cyclohexylene dimethylene terephthalate) is improved. In addition, by controlling a glass-transition temperature of the composition, no chipping is generated during ultrasonic welding, and the composition has a high welding strength, which is suitable for ultrasonic welding.

    摘要: The present invention relates to an easily-plated PC/ABS alloy and its preparation method. The PC/ABS alloy includes following components: 30-70 parts by weight (pbw) of PC resin, 15-65 pbw of ABS resin, 5-10 pbw of PEO resin, 0.1-1 pbw of antioxidant, and 0.1-1 pbw of lubricant. For preparation, blending the PC resin, ABS resin, PEO resin, antioxidant and lubricant in a mixer; and putting a mixture in a twin-screw extruder for granulation, thus producing easily-plated PC/ABS alloy. The method is simple and practicable. PEO resin makes PC/ABS surface have the property of hydrophilicity, which makes the etching solution easier to wet the surface when under etching, so that the etching becomes much easier. The binding force of hydrophilic group on the surface of PEO to the metal is strong. The binding force of PC/ABS alloy material is improved due to the combination between the chemical bond and physical force.

    摘要: Disclosed are a self-formaldehyde-scavenging heat-resistant ABS material and a preparation method therefor. The material includes following components in parts by weight: 75-95 parts of an ABS resin, 4-20 parts of a heat-resistant agent, 0.5-5 parts of a formaldehyde-scavenging masterbatch, 0.1-1 part of a formaldehyde-scavenging agent and 0.5-1 part of other auxiliaries. During preparation, the ABS resin, the heat-resistant agent and the other auxiliaries are mixed and fed through a main feeding port of a twin-screw extruder; and the formaldehyde-scavenging masterbatch and the formaldehyde-scavenging agent are fed to a rear section of the extruder, extruded and pelletized. By the method of the present invention, the content of formaldehyde in particles can be reduced by 40%, and the content of formaldehyde in a closed space can be reduced by 50% or more. Moreover, the content of other volatile organic compounds is reduced by 10% to 20%. Thus, the effects of controlling the formaldehyde emission from a material for a long time and inhibiting the content of formaldehyde in a space are achieved.
