Embodiment Construction

[0016] A preparation method of flame-retardant PE wood-plastic, the first step is to weigh 60-70kg of wood powder, 35kg of PE particles, 0.8kg of polyethylene wax, 8kg of calcium carbonate, 2kg of stearic acid, 0.3-1kg of lubricant EBS, and 0.8 kg of CPE kg, antioxidant 1010 0.3kg, UV531 0.5kg, compatibilizer 1.5kg, decabromodiphenyl ether 6kg, antimony trioxide 2kg, according to the solid material in the formula, put it in a plastic bucket except wood powder, The liquid material is placed in a bucket, and the PE material and wood flour are weighed and placed separately, and marked;

[0017] In the second step, add wood powder into the mixing pot according to the formula raw materials, then add the powder and liquid materials in the plastic bucket, cover the lid, set the stirring temperature to 110°C, start high speed, and stop when the temperature reaches 110°C Stir, open the lid, add PE material and continue to turn on the machine and start the low-speed button to stir for 2...

Abstract

The invention discloses a formula and a preparation method of a flame-retardant PE (Polyethylene) wood-plastic composite. The formula comprises wood meal, PE particles, polyethylene wax, calcium carbonate, stearic acid, a lubricant EBS (Ethylene Bis Stearamide), CPE (Chlorinated Polyethylene), an antioxidant 1010, an ultraviolet light absorber UV531, a compatilizer, decabromodiphenyl ether and antimonous oxide, all of which are subjected to mixture, granulation and extrusion. According to the formula and the preparation method disclosed by the invention, the defects of the prior art are overcome, the flame-retardant PE wood-plastic composite is extruded and molded based on the selected reasonable material formula and is high in oxygen index and good in flame-retardant effect.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a flame-retardant PE wood-plastic formulation and a preparation method thereof. Background technique [0002] The existing composite material has better processability and mechanical properties, and also has woody feeling. However, the flame retardancy of this material is not very good, which is very important for how to improve the flame retardancy of this composite material and suppress the production of smoke and poisonous gas when the composite material is burned or cracked. Its patent No. 201110093620.0 also discloses a flame-retardant composite material, but its molded oxygen index is low and the flame-retardant effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a flame-retardant PE wood-plastic formulation and its preparation method, which overcomes the shortcomings of the prior art, through selection of rea...
