Problems solved by technology

However, CN 200610015736.1 does not mention how to solve the problem of acid resistance (especially strong acid resistance), and the colored flat wire does not contain abrasives at the same time, so it cannot be used for abrasive brush filaments with grinding function
Using anti-hydrolysis agent or anti-acid agent alone has limited effect on improving the acid resistance of brush filaments

Embodiment 1

[0045] 1. Mix 4.93 kg of nylon 610 resin with 0.05 kg of polycarbodiimide (StaboxolP100) and 0.02 kg of antioxidant hindered phenol Irganox 1098.

[0046] 2. The above-mentioned mixture is passed through a twin-screw extruder, and 2.14 kilograms of emery abrasives are added from the side feeding port to carry out conventional melt spinning.

[0047] 3. The filaments coming out of the spinneret are cooled by water in the cooling tank, stretched by rollers, shaped by hot air, and finally packaged into industrial abrasive filaments.

[0048] 4. Take out a small amount of samples of the above-mentioned packaged abrasive filaments, and carry out acid treatment with pre-configured 0.1M sulfuric acid, and take out the samples after 40 days of treatment. The measured relative viscosities of the abrasive filaments before and after acid treatment were 3.27 and 3.26 respectively, and the relative viscosity change was reduced to 0.3%.

Embodiment 2

[0050] 1. Mix (4.955) kilograms of nylon 610 resin with (0.025) kilograms of sodium stearate and 0.02 kilograms of antioxidant hindered phenol Irganox 1098.

[0051] 2. The above-mentioned mixture is passed through a twin-screw extruder, and 2.14 kilograms of emery abrasives are added from the side feeding port to carry out conventional melt spinning.

[0052] 3. The filaments coming out of the spinneret are cooled by water in the cooling tank, stretched by rollers, shaped by hot air, and finally packaged into industrial abrasive filaments.

[0053] 4. Take out a small amount of samples of the above-mentioned packaged abrasive filaments, and carry out acid treatment with pre-configured 0.1M sulfuric acid, and take out the samples after 40 days of treatment. The measured relative viscosities of the abrasive filaments before and after acid treatment were 2.34 and 2.34 respectively, and the relative viscosity change was reduced to 0.

Embodiment 3

[0075] 1. Mix (4.91) kg of PBT resin, (0.05) kg of carbodiimide, (0.02) kg of hydrotalcite and (0.02) kg of antioxidant hindered phenol Irganox 1098 evenly.

[0076] 2. The above-mentioned mixture is passed through a twin-screw extruder, and 2.14 kilograms of emery abrasives are added from the side feeding port to carry out conventional melt spinning.

[0077] 3. The filaments coming out of the spinneret are cooled by water in the cooling tank, stretched by rollers, shaped by hot air, and finally packaged into industrial abrasive filaments.

[0078] 4. Take out a small amount of samples of the above-mentioned packaged abrasive filaments, and carry out acid treatment with pre-configured 0.1M sulfuric acid, and take out the samples after 40 days of treatment. The measured relative viscosities of the abrasive filaments before and after acid treatment were 2.92 and 2.90 respectively, and the relative viscosity change was reduced to 0.7%.

Abstract

The invention relates to industrial brush bristles and a brush comprising the brush bristles. The brush bristles comprise the following components: matrix resin, anti-hydrolysis agent and / or acid absorption agent and antioxidant agent. The invention is applicable to industry, particularly in burnishing, polishing, cleaning and other treatments after cutting marble and / or metal, and the like.

Description

technical field [0001] The invention relates to a brush filament and a method for preparing the brush filament, in particular to a brush filament used in a strong acid environment and a preparation method. Background technique [0002] Usually, all kinds of abrasive brush filaments used in industry with grinding function are made of synthetic materials such as nylon, polyester, polyolefin and abrasive materials such as corundum, aluminum oxide, artificial diamond, etc. in a certain proportion. Industrial brushes made of these abrasive filaments are often used for grinding, polishing, chamfering and cleaning after cutting of marble, metal, etc. For example, nylon 612, 610 is often used to make industrial brush filaments, and some polyesters such as PBT, PET, PTT and polyolefins such as PP are also used to prepare polymer synthetic materials for industrial brush filaments. However, these brush filaments can usually only be used in an environment with a pH of 4-10 at room temp...
