Abstract

The invention relates to the technical field of brushes, in particular to bristles with high water absorbing capacity. The bristles are characterized by being prepared from, by weight, 80-90 parts of straw fiber, 2-5 parts of phase solvent, 5-9 parts of polybutylene terephthalate, 2-4 parts of nanometer titania, 1-2 parts of dispersing agent, 0.5-1 part of chitosan, 20-30 parts of unsaturated polyester resin, 20-30 parts of vinyl ester resin, 0.8-2 parts of initiator and 0.2-1 part of low-shrinkage additive. According to the bristles, straw fiber is mixed with other materials including resin, robustness and tenacity are improved, straw fiber is high in moisture absorption capacity, large in number of gaps and cavities inside, large in specific area and high in impurity content and contains a certain amount of ash, impurities and ash have high moisture absorption capacity, and therefore the bristles can adsorb more oil paint or other liquid and painting effect is better.

Description

Technical field: [0001] The invention relates to the technical field of brushes, in particular to a bristle with strong water absorption. Background technique: [0002] The brush belongs to the industry category of hardware tools, so its use in this industry is self-evident. Specifically, the brush products used in the hardware and building materials industry include iron bar brushes, pipe brushes, nylon polishing brushes, polishing brushes for other materials, roller brushes, wire brush rollers, spring brush rollers, brick machine brushes, color brushes, etc. Tile machine brush, non-burning brick machine board brush, etc. In some cases, abrasive wire brush rolls containing silicon carbide or aluminum oxide are used for deburring and sanding the surface of castings or molded parts. In some painting treatments, the bristles of the hair brush are not strong in water absorption, and the bristles are not easy to absorb paint, resulting in poor brushing effect. Invention cont...
