Antistatic low-warping glass-fiber-reinforced weatherproof PP material and preparation method thereof

Abstract

The invention discloses an antistatic low-warping glass-fiber-reinforced weatherproof PP material and a preparation method thereof, belonging to the field of modification of high polymer materials. The antistatic low-warping glass-fiber-reinforced weatherproof PP material comprises, by mass, 50 to 72 parts of PP resin, 3 to 7 parts of a flexibilizer, 1.5 to 5 parts of a compatilizer, 15 to 25 parts of glass fibers, 7 to 12 parts of mica powder, 0.3 to 0.8 part of a light stabilizing agent, 1 to 2.5 parts of an antistatic agent, 0.1 to 0.4 part of a nucleating agent and 0.2 to 0.5 part of an anti-oxidant. The antistatic low-warping glass-fiber-reinforced weatherproof PP material prepared in the invention has low warping, high strength and antistatic performance and can effectively prevent dust; due to high weatherability of the material, the performance retention rate of the material can be maintained at 80% or more under the condition of high-temperature high-humidity xenon lamp aging; through usage of the flat glass fibers, low warping performance of the material is guaranteed on the prerequisite that high strength of the material is ensured; since propenyl elastomer and the nucleating agent are used, buckling deformation of the material can be effectively improved; and the material has good application prospects in the fields of fan blades of wind wheels, motors and the like.

Description

Technical field [0001] The invention belongs to the field of polymer material modification, and specifically relates to an antistatic low-warpage glass fiber reinforced weather-resistant PP material and a preparation method thereof. Background technique [0002] Generally used reinforced PP materials, in order to ensure the high strength of the material, will use ordinary glass fiber reinforcement, because the glass fiber will be oriented along the flow direction, resulting in a large difference between the shrinkage in the flow direction and the shrinkage perpendicular to the flow direction, and the shrinkage is unbalanced Cause warping. [0003] Glass fiber reinforced PP has good applications in household appliances due to its good processing properties, tensile strength and high temperature resistance. For example, it is used in air-conditioning wind turbine blades. Due to the requirement of air output, the wind turbine blades warp the material. The bending deformation has high...
