Problems solved by technology

[0002] At present, the raw materials of cable bridges are gradually eliminating steel products and using plastic products. The traditional formula has a large amount of addition, the effect is poor, the production cost is high, and the product fails to achieve the expected effect of use. Due to the high-strength hard plastic cable bridge produced by us, its Some of them are used outdoors, and must withstand the sun and rain, and adapt to the requirements of corrosive environments.

Abstract

The invention relates to a method for manufacturing a hard plastic bridge frame with waste plastic. The method for manufacturing a hard plastic bridge frame with waste plastic comprises the steps of (1) washing waste plastic with a plastic cleaning agent, then filtering the waste plastic for 10-15 minutes by putting into clear water, subsequently drying the filtered waste plastic by putting into a drying machine for 5-10 minutes; (2) cutting the waste plastic washed and purified in the step (1) into small pieces by using a cutting machine, then breaking the pieces into waste plastic particles by adding into a crushing machine, subsequently grinding the waste plastic particles into waste plastic powder by adding the waste plastic particles into a grinder; (3) mixing components of the hard plastic bridge frame in a mixing machine; and (4) adding the raw materials mixed uniformly in the step (3) into an extruder which squeezes and molds the targeted product. According to the method, the relevant performances of the hard bridge frame manufactured such as strength, and resistance to water, acid, alkali and salt meet the relevant requirements, is energy-saving and environment-friendly, and has no pollution and good flame retardancy.

Description

Technical field [0001] The invention relates to a method for processing rigid plastic bridge frames by using waste plastics. Background technique [0002] At present, the raw materials of cable trays are gradually phased out of steel products and replaced by plastic products. The traditional formula has a large amount of addition, the use effect is poor, the production cost is high, and the product fails to achieve the expected results. Due to the high-strength rigid plastic cable trays we produce, its Some of them are outdoor overhead, which must withstand the sun and rain, and adapt to the requirements of corrosive environments. Summary of the invention [0003] The purpose of the present invention is to provide a method for processing rigid plastic bridge frames using waste plastics, whose strength, water resistance, acid, alkali, salt and other related properties can meet relevant requirements, energy saving, environmental protection, pollution-free, and good flame retardancy....
