Description

Technical Field

[0001] The invention relates to the technical field of rubber surface coating formulas, and in particular to a puncture-resistant and wear-resistant rubber surface formula and coating process. Background Art

[0002] During the rubber manufacturing process, it is necessary to increase the adhesion of the rubber surface so that it can better combine with other materials and improve the stability, reliability and other performance of the overall structure, thereby extending the service life of the rubber and reducing the frequency of replacement and maintenance costs. Therefore, the rubber surface needs to be coated.

[0003] Most of the existing rubber is made of natural rubber or other rubber materials, and its internal wear resistance and puncture resistance are relatively limited. In addition, most coating materials are produced with water-resistant or flame-retardant base materials, which makes the rubber's wear resistance and puncture resistance weak. The puncture resistance effect is weak during normal use, reducing the service life of the rubber.

[0004] Therefore, in view of the fact that the above-mentioned rubber coating material is relatively fixed, resulting in weak wear resistance and puncture resistance of the rubber, weak puncture resistance effect during normal use, and reduced service life of the rubber, a puncture-resistant and wear-resistant rubber surface formula and coating process can be designed. Summary of the invention

[0005] In order to overcome the problem that the rubber coating material is relatively fixed, resulting in weak wear resistance and puncture resistance of the rubber, weak puncture resistance effect during normal use, and reduced service life of the rubber.

[0006] The technical scheme of the present invention is: a puncture-resistant and wear-resistant rubber surface formula, which is as follows in parts by weight: 70-100 parts of raw rubber, 20-40 parts of plastic resin slurry, 5-15 parts of ceramic powder, 10-30 parts of heat-resistant polymer, 2-10 parts of polysiloxane, 30-75 parts of carbon black, 6-12 parts of white carbon black, 5-20 parts of fiber material, 1-5 parts of nanomaterial, 2-10 parts of wear-resistant agent, 0.5-5 parts of antioxidant, 0.5-5 parts of plasticizer, 1-10 parts of softener, 2-6 parts of cross-linking agent, less than 10 parts of other additives and stainless steel mesh;

[0009] Preferably, the heat-resistant polymer includes isoprene, butadiene, styrene, and vinyl acetate.

[0010] Preferably, the carbon black includes 20 to 52 parts of carbon black (N330) and 10 to 23 parts of carbon black (N774).

[0011] Preferably, the fiber material includes 5% to 20% nylon, 1% to 10% glass fiber, 1% to 5% Nomex, and 5% to 20% polyester fiber; the nanomaterial includes 1% to 5% nano-silicon dioxide, 5% to 10% nano-carbonate, and 0.1% to 5% carbon nanotubes.

[0012] Preferably, the anti-wear agent includes silicon carbide, polyether, polyester, and the antioxidant includes antioxidant (D), antioxidant (4010NA), and antioxidant (AW).

[0013] Preferably, the plasticizer includes dioctyl phthalate (DOP) and dibutyl phthalate (DBP), and the crosslinking agent includes sulfur and peroxide.

[0014] Preferably, other additives include fillers, colorants, and accelerators.

[0015] A process for coating a puncture-resistant and wear-resistant rubber surface, comprising the above-mentioned puncture-resistant and wear-resistant rubber surface formulation, and the steps are as follows:

[0016] S1: Mix and prepare the coating material; use a cleaning device to brush and clean the surface of the base cloth and the stainless steel mesh to remove oil, dust and impurities;

[0017] S2: installing the cleaned base fabric on the coating device, coating the surface of the base fabric with a layer of primer, and after the primer is sprayed, installing the coating material on the coating device, and evenly coating the coating material on the surface of the base fabric by brushing, spraying or rolling the coating material through the coating device;

[0018] S3: After coating, the rubber can be dried and cured by heat curing, UV curing or chemical curing. After curing, the surface can be embossed and polished as needed;

[0019] S4: After the base fabric is cured, a layer of primer is coated on its surface. After the coating is completed, the stainless steel mesh is pressed on the base fabric, the primer is sprayed on the stainless steel mesh, and the base fabric is laid flat on the stainless steel mesh again to make the stainless steel mesh and the rubber base fabric bonded;

[0020] S5: After embossing and polishing, the coating is tested for appearance, thickness, etc., and its performance is tested by abrasion test and puncture test.

[0021] The beneficial effects of the present invention are as follows: the raw rubber is a material with high elasticity, high strength and good wear resistance; carbon black, white carbon black and fiber materials are used as reinforcing agents to improve the transparency and wear resistance of the rubber, and at the same time improve the puncture resistance and tensile strength of the rubber; the plastic resin slurry improves the wear resistance, tensile strength and tear resistance of the coating material rubber, and at the same time improves the adhesion between the coating material and the metal parts; the ceramic powder is used as a filler to fill the gaps between rubber molecules, enhance the strength and hardness of the rubber substrate, and improve the wear resistance and thermal stability of the rubber; the functionality and durability of the rubber are improved through the coordination between the substrates, thereby reducing the degree of wear of the rubber during use, extending the service life of the rubber, reducing the replacement frequency and cost, and then protecting the internal structure of the rubber and preventing liquid or gas leakage, and at the same time, the superposition of the stainless steel mesh and the base cloth is used to form an anti-piercing layer, thereby improving the puncture resistance of the rubber surface.
