Abstract

The invention discloses a preparation method of polypropylene type brush filaments, the method comprises the following steps: step 1, preparation of a polypropylene matrix material, to be more specific, polypropylene is soaked for 1-2h by using an activation elasticizing liquid at a soaking temperature of 65-75 DEG C, then dried at room temperature, and subjected to silane activation treatment. According to the invention, the surface activity of the polypropylene is improved by rare earth lanthanum chloride, and then the surface is dispersed and modified by a flexible medium so as to improve the surface tissue structure and achieve a flexible elasticization effect; by combination of the effects of the activation elasticizing liquid and the electric field, the flexible medium can be bettercontacted with a polypropylene material to improve the treatment effect; and then coupling treatment is adopted to improve the surface activity energy and enhance the adhesive force between the polypropylene and other materials to compound a prepared polypropylene matrix with nitrile rubber and a high-rebound polymer polyol, and then an adhesive reinforcing solution is adopted to improve the adhesive force among raw materials and improve the overall resilience.

Description

technical field [0001] The invention relates to the technical field of brush filaments, in particular to a method for preparing polypropylene-type brush filaments. Background technique [0002] Types of civilian brushes: Civilian brushes refer to the brushes used in people's daily work, such as toothbrushes, paint brushes, household cleaning brushes, cosmetic brushes, and various brushes for cleaning and removing sharp edges. The application range of industrial brushes covers almost all industries, and its main uses are cleaning, dust removal, polishing, etc. in the industrial production process. According to the production process, it can basically be divided into five categories: planting brushes, strip brushes, spring brushes, twist brushes, injection molding brushes, etc. According to the type of use, it can be divided into brush roller, roller brush, brush wheel, disc brush, strip brush, plate brush, special-shaped brush, etc. According to the brush wire material, it ...
