High-load brush disc for window wiper and production technology thereof

Abstract

The invention discloses a high-load brush disc for a window wiper. The high-load brush disc is characterized by being prepared from the following raw materials in parts by weight: 75 to 80 parts of a PP (Polypropene) reworked material, 12 to 18 parts of a PE (Polyethylene) reworked material, 5 to 14 parts of modified PP, 10 to 20 parts of ammonium trimethyl methyl sulfate, 4 to 10 parts of sodium bicarbonate, 5 to 8 parts of azodicarbonamide, 2 to 6 parts of pentaerythritol phenylpropionate, 30 to 35 parts of fatty alcohol polyoxyethylene ether, 2 to 4 parts of azodiisobutyronitrile, 6 to 8 parts of amino-2-methyl-1-propanol, 10 to 20 parts of a lubricant, 10 to 20 parts of a coupling agent, 1 to 2 parts of masterbatches and 2 to 3 parts of an antioxidant. According to the high-load brush disc disclosed by the invention, the PP reworked material and the PE reworked material are utilized as basic materials, full foaming and uniform extruding are carried out on the PP reworked material and the PE reworked material, heat absorption and heat release are balanced during a foaming process, higher melt strength of polypropene is kept, bubble pores are uniform and dense, no cracking exists, the homogeneity of a brush disc product can be increased, the density and the self weight of the brush disc product are reduced, and load during a working process can be borne to a larger extent by using the brush disc product as the brush disc of the window wiper.

Description

technical field [0001] The invention relates to the technical field of brush disc preparation, in particular to a high-load brush disc for window cleaners and a production process thereof. Background technique [0002] The brush plate is used for various purposes now, and the brush plate rotates by itself under the drive of power, so as to realize the brush cleaning on the surface of the object to be cleaned. In the prior art, the brush disc has the following problems: A. It has a large self-weight and requires a large driving power when rotating, which increases the load on the vehicle; B. The homogeneity of the brush disc is not good, and it is prone to eccentricity, which affects the cleaning effect; C. 1. A large amount of materials are consumed in the production process, which is not conducive to energy saving and environmental protection; D. The load bearing capacity of the brush plate is poor. Contents of the invention [0003] The present invention aims to provide...
