Abstract
The invention discloses an anti-impact ASA modified section which is prepared from the following raw materials in percentage by weight: 4-50% of polycarbonate, 5-20% of PMMA, 0.1-0.3% of lubricant, 0.3-1% of dispersant, 0.3-1% of antioxidant, 0.2-0.7% of ultraviolet light absorber, 2-6% of coloring pigment, 6-10% of calcium carbonate, 3-6% of stabilizer and the balance of ASA engineering plastic. The production steps include mixing, extrusion, traction, cooling, code spraying, film coating and cutting and storage. According to the anti-impact ASA modified section and production method disclosed by the invention, the ASA is modified by alloying; ASA, PC and PMMA are adopted for three-element blending; proper lubricant, antioxidant and ultraviolet light absorber are added to prepare the anti-impact ASA modified section; and therefore, the rigidity and toughness of the section are improved, the impact resistance is greatly enhanced, stronger weather resistance and ultraviolet resistance of the section are guaranteed, the anti-aging property of the section is remarkably improved, and the aims of improving the section arrangement quality and prolonging the service life are achieved.
Description
Technical field
The present invention relates to a kind of high weather-proof co-extrusion material PVC section bar and production method, belong to PVC section bar production field field.
Background technology
Plastic-steel section bar is because of its good heat-insulating property at present, the advantage such as sound-proofing properties and light easy processing is widely used, it is poor that but present employed plastic-steel section bar goods in use also exist shock resistance, easily occur aging, variable color, the problem such as become fragile, and tone is relatively single, thereby old use and the development that has seriously restricted plastic-steel section bar, in order to overcome this problem, method commonly used is to add such as thermo-stabilizer in base material at present, lubricant, modifier, impact modifying agent, weighting agent, antiager, the auxiliary ingredients such as tinting material, improve the ageing-resistant performance of finished section bar, but these supplementary additives are often expensive, thereby improved the production cost of plastics-steel products, be unfavorable for that it carries out sale, simultaneously in present employed supplementary additive, therefore often contain heavy metal " lead ", also increased the risk that the PVC section bar works the mischief to surrounding environment and human body.Simultaneously because there is some difference on the auxiliary ingredients that adds in traditional plastic-steel section bar and the plastic-steel section bar material, easily stress is crossed strong or skewness and the PVC distortion and the inconsistent bending that causes of the speed of expanding with heat and contract with cold that cause and twist etc.
