Description

Easy-to-clean brush wire

Technical Field

The invention relates to the technical field of brush wires, in particular to an easy-to-clean brush wire.

Background

The paint brush is usually prepared by bristles, but the bristles have the defects of non-wear resistance, easy breakage, non-corrosion resistance and the like, so that the service life of the brush is influenced; therefore, it is thought to replace bristles with brush filaments made of polymer materials, which have the advantages of wear resistance, high mechanical strength, high bending resilience, adjustable softness, long service life, etc. However, after the paint brush is made of the common brush wire, the paint attached to the brush wire is not easy to clean after the paint is applied, so that the paint brush cannot be reused, and the paint brushing cost is high.

Therefore, there is a need to provide a new easy-to-clean brush wire to solve the above technical problems.

Disclosure of Invention

The invention aims to provide an easy-to-clean brush wire which can reduce the cost of painting, and a paint brush made of the brush wire can easily clean the attached paint after painting.

In order to achieve the purpose, the invention adopts a technical scheme that: an easy-cleaning brush wire comprises the following components in parts by weight: 60-80 parts of PET (polyethylene terephthalate) polyester, 25-35 parts of PBT (polybutylene terephthalate) polyester, 5-15 parts of Teflon powder, 0.4-0.6 part of grafting auxiliary agent and 0.1-0.3 part of color master batch, wherein the PBT polyester is subjected to vacuum treatment at 160 ℃ for 4 hours.

Further, the weight portion of the teflon powder is 10 portions.

Further, the mass percent of the grafting auxiliary agent is 0.5 part.

Further, the grafting auxiliary agent is one or a mixture of more of diacrylate, styrene and maleic anhydride.

Compared with the prior art, the easy-to-clean brush wire has the beneficial effects that: this brush silk composition is simple, and by the paintbrush that this brush silk made, its whitewashes behind the paint, can be easier wash the adnexed paint on the brush silk for this paintbrush can used repeatedly many times, and not only the environmental protection has still improved the utilization ratio of paintbrush, effectively reduces the cost of brushing paint.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides an easy-to-clean brush wire, which comprises the following components in parts by weight: 60-80 parts of PET polyester, 25-35 parts of PBT polyester, 5-15 parts of Teflon powder, 0.4-0.6 part of grafting auxiliary agent and 0.1-0.3 part of color master batch, wherein the PBT polyester is subjected to vacuum treatment at 160 ℃ for 4 hours, and the color master batch is used for coloring the brush wires.

Further, the weight portion of the teflon powder is 10 portions.

Further, the mass percent of the grafting auxiliary agent is 0.5 part.

Example 1:

an easy-to-clean brush wire is prepared from PET polyester 60 parts, PBT polyester 25 parts, Teflon powder 5 parts, graft assistant 0.4 part, and color master 0.1 part through stirring, feeding into the hopper of extruder, extruding under high temperature and high pressure, heating, stretching and shaping.

Specifically, the grafting auxiliary agent is one or a mixture of more of diacrylate, styrene and maleic anhydride.

Example 2:

an easy-to-clean brush wire is prepared from PET (polyethylene terephthalate) polyester (70 portions), PBT (polybutylene terephthalate) polyester (30 portions), Teflon powder (10 portions), grafting assistant (0.5 portion) and color master (0.2 portion) through stirring, feeding into the hopper of extruder, extruding, heating and stretching at high temperature and high pressure.

Example 3:

an easy-to-clean brush wire is prepared from PET polyester (80 portions), PBT polyester (35 portions), Teflon powder (15 portions), graft assistant (0.6 portion) and pigment (0.3 portion) through stirring, loading in the hopper of extruder, extruding, heating and stretching at high temp. and high pressure.

Example 4:

an easy-to-clean brush wire is prepared from PET polyester 60 parts, PBT polyester 25 parts, Teflon powder 10 parts, graft assistant 0.5 part, and color master 0.1 part through stirring, feeding into the hopper of extruder, extruding under high temperature and high pressure, heating, stretching and shaping.

Example 5:

an easy-to-clean brush wire is prepared from PET polyester (80 portions), PBT polyester (35 portions), Teflon powder (10 portions), graft assistant (0.5 portion) and pigment (0.3 portion) through stirring, loading in the hopper of extruder, extruding, heating and stretching at high temp. and high pressure.

Comparative example 1:

an easy-to-clean brush wire is prepared from PET (polyethylene terephthalate) polyester (70 wt. portions), PBT (polybutylene terephthalate) polyester (30 wt. portions), grafting assistant (0.5 wt.) and pigment (0.2 wt.) through stirring, feeding to the hopper of extruder, extruding, heating and stretching at high temp. and high pressure.

Comparative example 2:

an easy-to-clean brush wire is prepared from PET (polyethylene terephthalate) polyester (70 portions), PBT (polybutylene terephthalate) polyester (30 portions), Teflon powder (10 portions) and color master (0.2 portion) through stirring, feeding to the hopper of extruder, extruding, heating and stretching at high temp. and high pressure.

The brush wires prepared in the examples 1 to 5 and the comparative examples 1 to 2 are cut into the same length after stress is eliminated, and are chemically corroded to form brush wires with certain taper, and then the brush wires are respectively prepared into paint brushes; after the paint brushes are respectively used for dipping in paint, the wall surface is painted, after painting is finished, the paint brushes are cleaned by using Tianna water (n-amyl acetate), and the cleaning effect of each paint brush is observed.

Experiments show that the paint brush prepared from the brush wire in the embodiment 2 has the best cleaning effect after painting, and can basically and completely clean the paint attached to the brush wire; the cleaning effect of example 3 was inferior; the cleaning effect of example 1 was inferior to that of example 3; the cleaning effect of comparative example 1 is the worst, and after the cleaning is carried out for many times, more paint still adheres to the brush filaments; comparative example 2 had a slightly better cleaning effect than comparative example 1, but was still far less excellent than example 3.

FIG. 1 is a graph showing a comparison of the cleaning effect of paintbrushes made from the filaments of example 2 and comparative example 1 after painting; the paint brush cleaning effect of comparative example 1 is shown in fig. 1 (left), and the paint brush cleaning effect of example 2 is shown in fig. 1 (right).

As is more evident from a comparison of the two figures (left) and (right) in FIG. 1, the brush filaments of the paint brush of example 2 were substantially free of adherent paint after cleaning; after the paint brush of comparative example 1 was cleaned, more paint remained on the brush filaments.

The brush wire has simple components, and the paint brush prepared from the brush wire can easily clean the paint attached to the brush wire after painting, so that the paint brush can be repeatedly used, thereby not only protecting the environment, but also improving the utilization rate of the paint brush and effectively reducing the cost of painting.

Of course, those skilled in the art will recognize that the above-described embodiments are illustrative only, and not intended to be limiting, and that changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
