Problems solved by technology

If the flame retardant formula is unreasonable, the flame retardant effect is not ideal. If the flame retardant performance is improved by increasing the amount of addition, it will increase the cost of the product and affect the bending performance of the material, making it difficult to meet the national standards.

Abstract

The invention provides an MPP electrostatic tube of force and a preparation method thereof. The MPP electrostatic tube of force comprises the following raw materials: MPP, light calcium carbonate, a plasticizer, a stabilizer, a compatilizer, a lubricant, CPE resin, a vinyl-propylene copolymer, graphene, modified whiskers, a compound inorganic flame retardant, vinyl trimethoxy silane, polyisocrotyl succinimide, an antioxidant and a colorant; the compound inorganic flame retardant is composed of rare earth hydroxide, aluminum hydroxide, magnesium hydroxide and ferric oxide; the modified whiskers are surfactant modified magnesium hydroxide sulfate whiskers. The preparation method comprises the following steps of: adding the raw materials into a mixer for mixing and stirring uniformly, wherein the mixing temperature is 100-120 DEG C and the mixing time is 10-15 minutes; after mixing uniformly, transferring into a cooling stirrer for stirring for 3-5 minutes at 40-50 DEG C at a low speed; and finally, plasticizing and slicing the raw materials in a cone-shaped twin-screw extruder to obtain MPP electrostatic tube particles of force, and then performing extrusion molding. The electrostatic tube of force provided by the invention has a good flame retardant property, impact resistance and heat resistance.

Description

technical field [0001] The invention belongs to the technical field of electric pipes, and in particular relates to an MPP electric pipe and a preparation method thereof. Background technique [0002] At present, there are two types of conventional power pipes on the market: MPP power pipes and CPVC power pipes. MPP power pipes are divided into excavation type and non-excavation type. MPP power pipes use modified polypropylene as the main raw material, which does not require a lot of dredging, excavation and damage to the road surface. Construction projects such as laying pipelines and cables in the lot. Compared with the traditional "grooving and buried pipe method", the non-excavation power pipe project is more suitable for the current environmental protection requirements, and removes the dust, traffic congestion and other disturbing factors caused by traditional construction. Pipelines are laid in areas where excavation operations are carried out, such as historic site...
