Description
Technical Field
The invention relates to the technical field of brush wire preparation, in particular to a high-adsorption paint conical brush wire and a preparation method thereof.
Background
The general paint brush is prepared by using the bristle and the imitated bristle chemical fiber, but the cost of using the bristle is high, and the brush has the problems of easy breakage, poor wear resistance and corrosion resistance and the like, so that the service life of the brush is short. At present, the preparation of the imitated bristle brush wire by using a high polymer material becomes a research hot spot in the field, and the prepared brush wire has the advantages of excellent mechanical property and wear resistance, long service life and the like. However, after some imitated pig bristle brush wires are manufactured into paint brushes in the market, the paint sucking quantity is insufficient, the paint is released unevenly in the painting process, and the problems of brush marks and the like are easy to occur.

Aiming at the defects in the prior art, the invention provides the high-adsorption paint conical brush wire and the preparation method thereof, and the conical brush wire has excellent softness and mechanical property, has high adsorption property on paint, can be uniformly released in the process of brushing paint, and is not easy to brush marks on the surface of the paint.
In order to achieve the above object, the present invention adopts the following technical scheme:
in one aspect, the invention provides a highly adsorptive paint cone brush filament, the raw materials for preparing the brush filament comprise: 100 parts of polybutylene terephthalate, 30-50 parts of polyethylene terephthalate, 15-20 parts of polypropylene, 8-14 parts of ceramic material, 0.1-1 part of colorant, 0.8-1.2 parts of compatilizer, 0.1-0.5 part of antioxidant, 0.1-0.5 part of hydrolysis resistance agent and 1-3 parts of lubricant.
In some embodiments, the polybutylene terephthalate has an intrinsic viscosity of 0.95 to 1.15dL/g and a relative molecular mass of 32000 to 35000.
Preferably, the polybutylene terephthalate has an intrinsic viscosity of 1.07dL/g and a relative molecular mass of 34000.
The source of the polybutylene terephthalate is not particularly limited and can be purchased commercially, including but not limited to polybutylene terephthalate from chinese petrochemical company, inc.
In some embodiments, the polyethylene terephthalate has an intrinsic viscosity of 0.6 to 0.7dL/g and a relative molecular mass of 30000 to 32000.
Preferably, the polyethylene terephthalate has an intrinsic viscosity of 0.627dL/g and a relative molecular mass of 31000.
The source of the polyethylene terephthalate is not particularly limited and can be commercially available, including but not limited to, polyethylene terephthalate available from petrochemical company, shanghai, petrochemical Co., ltd.
In some embodiments, the polypropylene has a melt flow rate of 15 to 25g/10min at 230 ℃/2.16 kg.
Preferably, the polypropylene has a melt flow rate of 20g/10min at 230℃C/2.16 kg.
The source of the polypropylene is not particularly limited and is commercially available, including but not limited to the polypropylene brand Tao Shidu Pont H701-20NA.
In some embodiments, the ceramic material comprises one or more of zirconium carbide, silicon carbide, boron carbide, aluminum oxide, silicon dioxide, talc.
In some embodiments, the ceramic material comprises alumina and talc, and the weight ratio is (0.5-1): 1.
in some embodiments, the alumina has a particle size of 600 to 1000 mesh, preferably 800 mesh.
The source of the alumina is not particularly limited and may be commercially available, including but not limited to, the alumina available from Guangxi Ke cube New Material Co.
In some embodiments, the talc has a particle size of 1000-1500 mesh, preferably 1250 mesh.
The source of the talc is not particularly limited and may be commercially available, including but not limited to, talc from the company of the chemical industry, the company of the morning of the new year.
The applicant found in the study that the specific polybutylene terephthalate, polyethylene terephthalate and polypropylene, especially the polybutylene terephthalate with the intrinsic viscosity of 0.95-1.15dL/g and the polyethylene terephthalate with the relative molecular mass of 32000-35000 and the intrinsic viscosity of 0.6-0.7dL/g and the polyethylene terephthalate with the relative molecular mass of 30000-32000 and the polypropylene with the melt flow rate of 15-25g/10min can continuously and uniformly prepare the brush filaments without breaking monofilaments, have excellent softness and high adsorptivity to paint, and the possible reasons are that the blending system of the polybutylene terephthalate and the polyethylene terephthalate has the capability of promoting crystallization, so that the brush filaments show better flexibility, and the polypropylene with the high melt flow rate can be in disorder arrangement and connection with the polybutylene terephthalate to form a nano-micro overlapped structure, so that the adsorption capacity of the brush filaments to the paint is improved. However, the polybutylene terephthalate and the polyethylene terephthalate are easy to undergo transesterification reaction in the blending process, and can cause negative influence on mechanical properties, and the applicant finds that by adding a certain ceramic material, particularly alumina and talcum powder with specific particle sizes, into the system, the mechanical properties of the brush filaments are improved, and the wear resistance of the brush filaments is ensured, because the ceramic material is dispersed in the system to inhibit transesterification reaction of two polyesters, and meanwhile, the wear resistance is also achieved.
In some embodiments, the compatibilizing agent comprises one or more of an ethylene-vinyl acetate copolymer, an ethylene-glycidyl methacrylate copolymer, an ethylene-n-butyl acrylate-glycidyl methacrylate copolymer.

In some embodiments, the lubricant is at least one of stearic acid amide, stearic acid, oleic acid amide.
The invention further provides a preparation method of the high-adsorption paint conical brush wire, which comprises the following steps of:
s1, weighing raw materials according to a proportion, respectively drying polybutylene terephthalate, polyethylene terephthalate, polypropylene and ceramic materials, adding the dried materials into a mixing mill for mixing, cooling and cutting into colloidal particles;
s2, mixing and dispersing the obtained colloidal particles with a colorant, a compatilizer, an antioxidant, an anti-hydrolysis agent and a lubricant;
s3, drying the dispersed mixture, carrying out melt extrusion by an extruder, cooling, stretching, heating for shaping, and cooling to obtain a primary brush yarn;

TABLE 2
| Numbering device | Elongation at break (%) | Breaking strength (MPa) |
| Example 1 | 35.8 | 345 |
