Problems solved by technology

In order to meet the requirement that the rubber material can withstand the ablation of high-energy laser rays, the rubber material needs to be filled with a large amount of flame-retardant fillers. However, traditional flame-retardant fillers will not only release a large amount of toxic and harmful fumes during the flame-retardant process, but also cause excessive filling. Causes problems such as degradation of rubber material performance, so it cannot be regarded as a good laser engraving resistant filler

Embodiment 1

[0024] At room temperature, wrap 100 parts of natural rubber on double rollers on a rubber mixing machine, then add 5 parts of zinc oxide and 2 parts of stearic acid in sequence, and mix for 0.5 minutes; then add 0.5 part of antioxidant RD, add antioxidant 4010NA to 0.5 Part, mix for 2 minutes; then add 0.01 part of VN3 white carbon black, 1 part of N220 carbon black and 0.5 part of Si69 in batches, then mix for 5 minutes, then add 0.01 part of chlorinated paraffin and 1 part of red phosphorus, mix Refining for 0.5 minutes, and finally adding 1.5 parts of accelerator CZ and 3 parts of sulfur in the open mill, thin pass 5 times to eject the sheet, then park for 4 hours, then return to refining for 5 minutes and vulcanize to form a composite material.

[0025] The accelerator CZ is N-cyclohexyl-2-benzothiazole sulfenamide; Si69 is bis(triethoxysilylpropyl) tetrasulfide; the antioxidant RD is 2,2,4-trimethyl -1,2-Dihydroquinoline polymer (belonging to ketone-amine reaction product t...

Embodiment 2

[0027] At room temperature, wrap 100 parts of natural rubber on double rollers on a rubber mixing machine, then add 5 parts of zinc oxide and 2 parts of stearic acid in sequence, and mix for 0.5 minutes; then add 4 parts of antioxidant RD, add antioxidant 4010NA to 5 1 part and 1 part of protective wax, mixed for 5 minutes; then add 10 parts of VN3 white carbon black, 10 parts of N234 carbon black and 4 parts of Si69 in batches, then add 10 parts of brominated epoxy resin, 10 parts of alumina and 5 parts of red phosphorus, then mixed for 10 minutes, and finally add 1.5 parts of accelerator CZ, 0.2 parts of accelerator TT and 3 parts of sulfur in the open mill, thin pass 5 times, and then stop for 4 hours, then re-mix 5 minutes and vulcanization molding to obtain composite material.

[0028] The accelerator TT is tetramethylthiuram disulfide; the protective wax is a kind of anti-aging agent, which can prevent ozone aging and prolong the service life; the brominated epoxy resin bel...

Embodiment 3

[0030] At room temperature, wrap 100 parts of natural rubber on double rollers on a rubber mixing machine, then add 4 parts of zinc oxide and 1 part of stearic acid in sequence and mix for 0.5 minutes; then add 4 parts of antioxidant MB, and add antioxidant 445 to 5 Parts and 4 parts of protective wax, mix for 5 minutes; then add 50 parts of T383 white carbon black, 0.5 parts of N234 carbon black and 4 parts of Si75 in batches, then mix for 10 minutes, then add 20 parts of hydrotalcite and 0.2 parts Add 5 parts of paraffin oil and mix for 10 minutes. Finally, add 1.5 parts of accelerator DM, 3 parts of accelerator DTDM and 2 parts of sulfur in the open mill, and pass 5 times. The film is discharged, then parked for 4 hours, then re-melted for 5 minutes and vulcanized to form a composite material.

[0031] The accelerator DM is 2,2'-dithiodibenzothiazole; the accelerator DTDM is 4,4'-dithiodimorpholine; Si75 is bis(triethoxysilylpropyl) disulfide Antiaging agent MB is 2-mercaptob...

Abstract

The invention relates to a rubber composite material for laser engraving, and aims to provide a rubber composite material for laser engraving having excellent routine physical and mechanical performances and excellent laser engraving resistance. The rubber composite material with excellent laser engraving resistance is prepared by compounding a dual-component laser engraving resistant filler with a polymer material (rubber). The dual-component laser engraving resistant filler comprises a flame retardation component and a supporting component, so the rubber composite material has excellent routine physical and mechanical performances and has excellent laser engraving resistance.

Description

Technical field [0001] The invention relates to a rubber composite material for laser engraving, which is used for printing plates and processing and manufacturing industries involving rubber products, such as aviation, electronics, automobiles, and medical treatment. Background technique [0002] Laser has the advantages of good directionality, high energy density, and good monochromaticity. It is very suitable for material processing, so it has always been valued by the scientific research field and industry. [0003] Laser engraving refers to the use of a laser beam to change the shape or performance of the sample. It is a high-power density spot formed by focusing of the laser beam. In a few microseconds, the temperature of the spot area rises to the melting point or even the boiling point of the material. , So that the material in the irradiated area will melt and vaporize, ablate or reach the ignition point immediately. When the laser beam moves along the set path, the photo...
