Description

Technical Field

[0001] This invention belongs to the field of floor mat technology, specifically relating to a non-slip, wear-resistant, fully dyed floor mat and its production process. Background Technology

[0002] Rubber floor mats are floor mats made of natural rubber, synthetic rubber, or other polymer materials. Anti-slip and wear-resistant floor mats are specifically designed to enhance the anti-slip performance and durability of floors, and are commonly used in homes, commercial spaces, and industrial areas.

[0003] Common materials for anti-slip and wear-resistant floor mats include EPDM rubber and styrene-butadiene rubber, which are characterized by high elasticity, anti-slip and wear resistance, sound absorption and shock absorption, and environmental friendliness. They are comfortable underfoot and suitable for gyms, playgrounds, parks, and other sports venues. Especially in sports venues like gyms, sweat from exercisers will drip onto the mats. Rubber materials themselves do not have antibacterial properties. Rubber mats with slightly better antibacterial effects add silver ion antibacterial agents to their surface wear-resistant layer, but this has poor durability and high operating costs. Some mats add nanofillers to the surface layer, which offer higher antibacterial stability and durability, but the antibacterial effect is often not as good as silver ion antibacterial agents. Therefore, it is necessary to simultaneously improve the durability and antibacterial properties of the antibacterial materials in rubber mats. Summary of the Invention

[0004] The purpose of this invention is to provide a non-slip, wear-resistant, fully dyed floor mat, which improves the antibacterial properties and durability of the mat through a self-made functional composite powder; the second purpose of this invention is to provide a production process for a non-slip, wear-resistant, fully dyed floor mat.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A non-slip, wear-resistant, fully dyed floor mat includes, in structure, a base layer made of styrene-butadiene rubber particles bonded and cured, and a composite surface layer on the base layer.

[0007] A manufacturing process for a non-slip, wear-resistant, fully dyed floor mat includes the following steps:

[0008] Step 1: Add styrene-butadiene rubber granules, silica, calcium carbonate powder, phosphorus flame retardant, functional composite powder, glass fiber, UV absorber, antioxidant, foaming agent, accelerator, sulfur, stearic acid, liquid paraffin and color powder into a mixer and mix at 150-160℃ for 2-3 minutes. Then transfer to a flat vulcanizing machine and vulcanize under pressure at 160-180℃ and 12-14MPa for 20-25 minutes. Cut into shape to obtain a surface layer with a thickness of 3-5mm.

[0009] Step 2: Mix styrene-butadiene rubber granules and polyurethane adhesive at a mass ratio of 7-8:1 to obtain a base mixture. Spread the base mixture evenly in a mold and attach the top layer to its surface. Cure and shape it under a pressure of 160-180℃ and 6-8MPa. Demold the mold to obtain a non-slip, wear-resistant, fully dyed floor mat.

[0010] Furthermore, the mass ratio of styrene-butadiene rubber granules, silica, calcium carbonate powder, phosphorus-based flame retardant, functional composite powder, glass fiber, UV absorber, antioxidant, foaming agent, accelerator, sulfur, stearic acid, liquid paraffin, and colorant is 10-12:3-4:3-4:1-1.5:1-1.2:0.3-0.5:0.3-0.5:0.3-0.5:0.8-1.3:0.5-1:0.15-0.16:0.13-0.15:3-4:1.5-2.5.

[0011] Furthermore, the phosphorus-based flame retardant is either n-butyldihydroxypropylphosphine oxide or trihydroxypropylphosphine oxide.

[0012] Furthermore, the length of the glass fiber is 2-3 mm.

[0013] Furthermore, the ultraviolet absorber is either 2,4-dihydroxybenzophenone or 2-hydroxy-4-n-octyloxybenzophenone.

[0014] Furthermore, the antioxidant is any one of antioxidant 168, antioxidant 702, and antioxidant 703.

[0015] Furthermore, the foaming agent is azodicarbonamide.

[0016] Furthermore, the accelerator is any one of accelerator M, accelerator DM, and accelerator MZ.

[0017] Furthermore, the functional composite powder is prepared through the following steps:

[0018] Step 1: Add lanthanum chloride, ethylenediamine, and deionized water to a reaction vessel and stir for 3-5 minutes at 20-25℃ and 200-300 r / min. Then add lysine and zinc oxide precursor and continue stirring for 10-20 minutes. Disperse ultrasonically for 5-10 minutes and keep the reaction at 200-220℃ for 12-16 hours. Through hydrothermal reaction, carbon dots with inherited carboxyl and amino groups are generated using ethylenediamine and lysine as carbon sources. Lanthanum chloride is converted into lanthanum oxide. These lanthanum-doped carbon dots will grow using zinc oxide particles as templates. Cool the reaction solution naturally and filter it through a 0.45 μm filter. Collect the filtrate and freeze-dry it to obtain antibacterial agent powder.

[0019] Step 2: Add N-phenyl-p-phenylenediamine and toluene to the reaction vessel and stir until N-phenyl-p-phenylenediamine dissolves. Then, under nitrogen protection, add 3-isocyanate-propyltrimethoxysilane and dibutyltin dilaurate as a catalyst to the reaction vessel. Stir and react for 3-3.5 h at 50-55℃ and 800-1000 r / min. Remove toluene by rotary evaporation and extract the remaining product with anhydrous ethanol to remove unreacted monomers to obtain the modified antioxidant.

[0020] Step 3: Add the antibacterial agent powder, modified antioxidant, and 90% ethanol aqueous solution to the reaction vessel, stir at 200-300 r / min for 3-5 min, then ultrasonically disperse for 5-10 min, adjust the pH value to 4-4.5 with acetic acid, stir and react at 50-60℃ for 10-12 h, centrifuge and filter, wash the precipitate 3-5 times with anhydrous ethanol, and vacuum dry to obtain the functional composite powder.

[0021] Furthermore, in step 1, the ratio of lanthanum chloride, ethylenediamine, deionized water, lysine, and zinc oxide precursor is 1.2-1.25g: 1mL: 400-500mL: 4.5-5g: 12-13.5g.

[0022] Furthermore, in step 2, the ratio of N-phenyl-p-phenylenediamine, toluene, 3-isocyanate-propyltrimethoxysilane and dibutyltin dilaurate is 4.4-4.5g: 60-65mL: 3.8-4g: 0.1g.

[0023] Furthermore, in step 3, the ratio of antibacterial powder, modified antioxidant, and ethanol aqueous solution is 10g:1.5-1.8g:350-400mL.

[0024] Furthermore, the zinc oxide precursor in step 1 is prepared through the following steps:

[0025] Hexadecyltrimethylammonium bromide, zinc nitrate hexahydrate, and deionized water were added to a reaction vessel and stirred at 200-500 rpm for 20-30 min. Then, a sodium hydroxide solution with a molar concentration of 1 mol / L was added to the reaction vessel, and the mixture was stirred at 20-25°C for 100-120 min. The mixture was then kept at 180-185°C for 30-40 min, allowed to cool naturally, centrifuged and filtered, and the precipitate was washed 3-5 times with anhydrous ethanol. The precipitate was then vacuum dried at 50-60°C and ground to obtain the zinc oxide precursor.

[0026] Furthermore, the ratio of hexadecyltrimethylammonium bromide, zinc nitrate hexahydrate, deionized water, and sodium hydroxide solution is 2.5-2.65g: 19-20g: 80-100mL: 140-150mL.

[0027] The beneficial effects of this invention are:

[0028] The surface layer of the anti-slip and wear-resistant fully dyed floor mat of this invention incorporates functional composite materials during the production process. These functional composite materials have excellent antibacterial and anti-aging effects, which help to increase the antibacterial performance and durability of the fully dyed floor mat product.

[0029] In the preparation of the functional composite powder of this invention, zinc oxide precursor is used as the main material. The zinc oxide precursor is generated through the reaction of zinc nitrate and sodium hydroxide. Through a hydrothermal reaction, using ethylenediamine and lysine as carbon sources, carbon dots inheriting carboxyl and amino groups are generated. Lanthanum chloride is converted into lanthanum oxide. These lanthanum-doped carbon dots grow using zinc oxide particles as templates to form a stable composite structure, thereby preparing the antibacterial powder. During the hydrothermal reaction, the zinc oxide precursor forms zinc oxide with nanoscale particle size, which can exert good antibacterial effects. The composite with lanthanum oxide has a synergistic effect, enhancing the photocatalytic activity of zinc oxide and improving the bactericidal effect. Simultaneously, the carbon dots, with their good antibacterial properties, are modified with lysine to increase the amino groups on the carbon dot surface. This generates electrostatic interactions with the negative charge on the bacterial surface, destroying the bacterial cell structure and causing lysis and death, further enhancing the bactericidal activity of the functional composite powder.

[0030] The isocyanate group in 3-isocyanate-propyltrimethoxysilane reacts with the amino group on the antioxidant N-phenyl-p-phenylenediamine to prepare a modified antioxidant. Under weakly acidic conditions, the modified antioxidant is hydrolyzed to release silanol groups. The carboxyl groups inherited in the antibacterial agent powder are then bonded in situ to the silanol groups, ultimately preparing a functional composite powder. By coating the antibacterial agent powder particles with the modified antioxidant through in-situ bonding, the dispersibility and compatibility of the antibacterial agent powder in the styrene-butadiene rubber matrix are improved, which helps to further enhance the mechanical properties of the surface layer material. Furthermore, it can reduce the migration of N-phenyl-p-phenylenediamine during use, which helps to increase the aging resistance and stability of the surface layer material. Detailed Implementation
