Abstract

The invention discloses a preparing method for an uvioresistant high-strength composite material. The method comprises the steps that weighed PA resin, PP resin, glass fiber and plant fiber are arranged in a drying machine to be dried, the dried glass fiber and the dried plant fiber are arranged in a mixer, and a mixture a is obtained and used later; the dried PA resin, the dried PP resin, a compatilizer, an antioxidant, a filling agent and fire retardant are arranged in the mixer to be mixed, and a mixture b is obtained; and the mixture b is slowly poured into a double-screw extruder hopper, the speed of screws is controlled to range from 300 r / min to 400 r / min, the temperature of areas of the extruder is controlled to range from 190 DEG C to 215 DEG C, the temperature of a machine head ranges from 210 DEG C to 218 DEG C, the mixture a is added from the sixth area, melt is extruded out from the machine head, and the composite material is obtained. According to the preparing method, the PA resin and the PP resin are modified through the glass fiber and the plant fiber, the uvioresistant performance of the composite material can be greatly improved, and meanwhile the strength of the composite material can be improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of an ultraviolet-resistant high-strength composite material. Background technique [0002] PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, and has a low coefficient of friction, certain flame retardancy, and is easy to process. PP materials have a low heat distortion temperature, low transparency, low gloss, and low rigidity, but have stronger impact strength. However, the anti-ultraviolet properties of these two materials are not ideal, and the strength of a single material cannot meet the needs of industrial production. [0003] With the development of society and the progress of industry, higher requirements are put forward for materials in terms of UV resistance and strength. Among the existing preparation methods for materials, there...
