Description

TECHNICAL FIELD

[0001] The present application relates to the field of non-slip mats, in particular to a carpet non-slip mat and a preparation method thereof. BACKGROUND

[0002] As a common protective material for home and commercial places, the non-slip mat is mainly used to improve the friction of the ground and avoid the displacement of the carpet or the slipping of the person. The existing non-slip mat is mainly divided into two types of PVC and latex. The PVC non-slip mat has low raw material cost, but needs to add plasticizer, which is easy to separate out during use, not only harmful to human health, but also pollutes the ceramic tile floor (produces oil stains, material corrosion, etc.), and the PVC is difficult to degrade, which has poor environmental protection. The latex non-slip mat gradually becomes the preferred direction to replace the PVC non-slip mat due to its advantages of degradability and good elasticity, but the existing latex non-slip mat still has many technical problems to be solved, for example: the existing technology uses mixed latex liquid of natural latex and butadiene rubber as the base material, the surface polarity of the natural latex is strong, and the friction interface with the carpet and ceramic tile is easy to form a sliding layer, which affects the improvement effect of the non-slip coefficient. In addition, the existing technology adopts the processing method of coating and scraping the mesh cloth, even if the mixed latex liquid contains polyacrylamide, casein and other additives to promote the plasticization and crosslinking with the mesh cloth, there is still the problem of uneven impregnation of the latex liquid, which leads to the local delamination and insufficient adhesion stability of the product after long-term use, further affecting the consistency of the non-slip performance.

[0003] In summary, the existing PVC non-slip mat has poor environmental protection and safety, and the existing latex non-slip mat has problems of insufficient non-slip coefficient and poor adhesion stability, which is difficult to meet the comprehensive needs of home and commercial places for non-slip mats, so it is urgent to develop a carpet non-slip mat with better performance and a preparation method thereof. SUMMARY

[0004] In view of the shortcomings of the prior art, the purpose of the present application is to provide a carpet non-slip mat and a preparation method thereof, which aims to solve the above problems.

[0018] The application provides a carpet anti-skid pad and a preparation method thereof. In order to make the purpose, technical scheme and effect of the application more clear and explicit, the application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application, and do not limit the protection scope of the application.

[0019] The application provides a preparation method of a carpet anti-skid pad, comprising the following steps: (1) The polyester fiber is dried in an oven at 100-110 DEG C for 20-30 min, so as to remove the water and impurities on the surface of the polyester fiber and ensure that the water in the polyester fiber is fully volatilized. The D number of the polyester fiber is 1.5-3.0D, and the above-mentioned fiber fineness can ensure that the fiber has sufficient specific surface area, so that the synthetic styrene-butadiene latex and the curing agent, emulsifier and other additives can fully penetrate and adsorb on the surface and inside of the fiber, forming a composite structure of uniform fiber skeleton latex coating, avoiding the problems of insufficient strength caused by too fine fiber, or difficult penetration of latex and insufficient bonding caused by too thick fiber.

[0020] (2) Add 100 parts of synthetic styrene-butadiene latex into the stirring kettle, start the stirring device, and stir at a speed of 500-800 r / min for 5-10 min to uniformly disperse the latex system. Add 6-10 parts of vulcanizing agent, 2-4 parts of emulsifier, and 0.2-0.4 parts of antioxidant into the stirring kettle, continue to stir at a speed of 500-800 r / min for 15-20 min to ensure that the additives are completely dissolved and dispersed in the latex system. Reduce the stirring speed to 300-500 r / min, slowly add 15-20 parts of foaming agent, and stir for 8-12 min to obtain an impregnating solution that is uniform and has no obvious bubbles. The foaming agent must be added last. If the foaming agent is added before the emulsifier, a large amount of bubbles will be generated (foaming), which is not conducive to the uniform mixing of the polyester fibers and affects the performance stability of the non-slip pad.

[0021] The high stirring speed is used first to ensure that the additives are quickly and sufficiently dispersed, and then the foaming agent is added at a low stirring speed to avoid the generation of new excess bubbles during high-speed stirring, thereby ensuring that the impregnating solution has no obvious bubbles.

[0022] Specifically, the solid content of the synthetic styrene-butadiene latex is 55-65%, and the copolymerization ratio of butadiene to styrene in the synthetic styrene-butadiene latex is (60-70):(40-30). The above solid content range can avoid the problems of insufficient viscosity of the impregnating solution, poor adhesion of the latex on the surface of the polyester fibers, loose structure of the cured product, and decreased wear resistance and slip resistance, and can also avoid the defects of poor flowability of the impregnating solution, difficulty in fully penetrating the interior of the polyester fibers and the interstitial space between the fiber bundles, and uneven impregnation caused by high solid content. The copolymerization ratio of (60-70):(40-30) can regulate the molecular structure and surface properties of the synthetic styrene-butadiene latex. The butadiene segment endows the latex with excellent flexibility and elasticity, and the styrene segment improves the rigidity and surface roughness of the latex. The synergistic effect of the two segments overcomes the shortcomings of the existing natural latex, such as strong surface polarity and easy formation of a sliding layer, improves the friction coefficient between the non-slip pad and the carpet or ceramic tile, ensures the compatibility of the latex with the vulcanizing agent, emulsifier, and other additives, and the interfacial bonding force between the latex and the polyester fibers, and finally realizes the performance improvement of the product in terms of slip resistance, mechanical strength, and use stability.

[0023] Vulcanizing agent (6-10 parts, sulfur / dicumyl peroxide): 6-10 parts of the ratio is suitable for the cross-linking needs of 100 parts of synthetic styrene-butadiene latex. If the amount is insufficient, it will lead to insufficient cross-linking of the latex molecular chain, resulting in insufficient product strength, wear resistance and adhesion, and long-term use will easily cause delamination and deformation. If the amount is too much, it will cause excessive cross-linking, resulting in increased product brittleness and decreased elasticity, affecting the cushioning effect of the non-slip pad. In terms of type, both sulfur and dicumyl peroxide are efficient vulcanizing agents suitable for synthetic styrene-butadiene latex. Sulfur has the advantages of high cross-linking efficiency and good compatibility with latex, while dicumyl peroxide can stably function at a curing temperature of 120-140°C. Both of them can promote the synthetic styrene-butadiene latex to form a dense three-dimensional network structure, while strengthening the interfacial bonding force between the latex and the polyester fiber, making the composite structure more firm, effectively solving the defects of poor adhesion stability and poor wear resistance of existing latex non-slip pads due to insufficient cross-linking, thereby improving the non-slip performance and service life of the product.

[0024] Emulsifier (2-4 parts, anionic: non-ionic = (3-2): 1, the anionic emulsifier is sodium dodecyl sulfate or sodium dodecyl benzene sulfonate, and the non-ionic emulsifier is a polyoxyethylene ether emulsifier (such as OP-10, TX-10). The above addition amount can avoid insufficient amount leading to too high interfacial tension between synthetic styrene-butadiene latex and vulcanizing agent, antioxidant and other additives, causing stratification and precipitation, affecting the uniformity of the impregnation liquid, and preventing excessive amount from causing abnormal system viscosity or residual additives affecting product non-slip performance and environmental friendliness. The selected sodium dodecyl sulfate or sodium dodecyl benzene sulfonate has strong dispersion ability and can quickly break the aggregation between latex particles, while the polyoxyethylene ether has good compatibility and is less affected by the system pH value, which can enhance the interfacial affinity between the latex and the polyester fiber. The combination of the two not only solves the problem of poor dispersion effect or insufficient stability of a single emulsifier, but also ensures that the impregnation liquid remains uniform and stable throughout the stirring, impregnation and curing process, avoiding uneven impregnation.

[0025] Antioxidant (0.2-0.4 parts, 2,6-di-tert-butyl-p-cresol (BHT) or tetrakis [beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol (1010)): The above-mentioned amount of antioxidant can effectively capture the free radicals generated during the processing (120-140°C curing) and use of the latex, inhibit the oxidative degradation of the molecular chain, and avoid problems such as brittleness, discoloration, and performance degradation of the product. Too much use will cause the residue of the additive, and the antagonistic effect with other components (such as vulcanizing agent), thereby affecting the cross-linking efficiency and slip resistance of the product. The two selected antioxidants are both phenolic primary antioxidants, which have excellent compatibility with synthetic styrene-butadiene latex and strong chemical stability, and will not decompose and fail within the curing temperature range. Among them, BHT has the advantages of high anti-aging efficiency and cost adaptability, and 1010 has the characteristics of long-lasting anti-aging and no adverse interaction with the latex system.

[0026] Foam stabilizer (15-20 parts, polyether-modified polysiloxane / long-chain (C12-C18) alkyl-modified polysiloxane): The above-mentioned amount of foam stabilizer can effectively eliminate the excessive coarse bubbles generated during stirring and impregnation, and stabilize the small and uniform bubbles in the system. When the amount is insufficient, the product surface will have defects such as protrusions and pores, or when the amount is too much, the compatibility of the latex system will decrease. Polyether-modified polysiloxane, by introducing polyether segments, has both hydrophilic and hydrophobic properties, and can efficiently cooperate with synthetic styrene-butadiene latex and emulsifiers, etc., to form a stable film at the gas-liquid interface, preventing bubble coalescence or rupture. Long-chain (C12-C18) alkyl-modified polysiloxane, by virtue of the compatibility of long-chain alkyl groups, slowly diffuses and uniformly covers the bubble surface, further improving the bubble stability. Both of them can ensure that the impregnation liquid remains in a uniform state without obvious bubbles in the subsequent process.

[0027] (3) The treated polyester fiber is completely immersed in the impregnation liquid, the impregnation temperature is 35-40°C (this temperature range is suitable for the viscosity characteristics of synthetic styrene-butadiene latex, to avoid high viscosity of the latex at low temperature, making it difficult to penetrate, or premature cross-linking of the latex caused by high temperature), and the impregnation time is 10-15 min, to ensure that each single filament and fiber bundle of the polyester fiber fully absorbs the impregnation liquid, and to avoid uneven impregnation. After impregnation, the polyester fiber is taken out of the impregnation liquid and naturally drained for 5-8 min to remove the excess impregnation liquid on the surface of the polyester fiber, to avoid accumulation of slurry on the surface of the product after curing.

[0028] (4) The polyester fiber is heated at a temperature of 120-140°C for 20-30 min to cure the impregnation liquid and obtain the carpet slip mat. The curing temperature of the present application is lower than 150-160°C of the prior art, which is suitable for the cross-linking reaction rate of the vulcanizing agent (sulfur / dicumyl peroxide). If the curing temperature is too high, the latex film forming speed is too fast, and a large number of internal bubbles escape too quickly, breaking through the film layer, which will cause product defects (such asFigure 2 The protrusions shown) while too high a curing temperature will cause the product to yellow and age, affecting appearance. The curing time described above can ensure that the cross-linking reaction proceeds sufficiently, forming a stable composite structure and avoiding poor adhesion and insufficient wear resistance caused by insufficient curing.

[0029] Please refer to Figure 1 The application also provides a carpet non-slip pad prepared by the above method, which has a static friction coefficient of ≥1.1.

Reduce the stirring speed to 400 r / min, slowly add 16 parts of foaming agent (long-chain (C14) alkyl-modified polysiloxane), stir for 10 min, and obtain an impregnating solution which is uniform and has no obvious bubbles.

[0037] (3) Completely immerse the treated polyester fiber into the impregnating solution, the immersion temperature is 40℃, and the immersion time is 10 min. After the immersion is completed, take out the polyester fiber from the impregnating solution and naturally leach for 5 min.

[0038] (4) Heat the polyester fiber at a temperature of 140℃ for 20 min to solidify the impregnating solution, and obtain a carpet non-slip pad.

[0039] Example 3 A method for preparing a carpet non-slip pad, comprising the following steps: (1) Dry the polyester fiber in an oven at a temperature of 105℃ for 25 min, wherein the D number of the polyester fiber is 1.5D.

[0040] (2) Add 100 parts of synthetic styrene-butadiene latex (copolymerization ratio of butadiene and styrene is 70:30) into a stirring kettle, start the stirring device, the stirring speed is 800 r / min, and stir at a uniform speed for 5 min. Add 10 parts of vulcanizing agent (sulfur), 4 parts of emulsifier (3 parts of sodium dodecyl benzene sulfonate and 1 part of polyoxyethylene ether emulsifier (TX-10)), and 0.4 parts of antioxidant (1010) into the stirring kettle, keep the stirring speed at 800 r / min, and continue to stir for 15 min. Reduce the stirring speed to 500 r / min, slowly add 20 parts of foaming agent (long-chain (C16) alkyl-modified polysiloxane), stir for 8 min, and obtain an impregnating solution which is uniform and has no obvious bubbles.

[0041] (3) Completely immerse the treated polyester fiber into the impregnating solution, the immersion temperature is 35℃, and the immersion time is 10 min. After the immersion is completed, take out the polyester fiber from the impregnating solution and naturally leach for 6 min.

[0042] (4) Heat the polyester fiber at a temperature of 120℃ for 30 min to solidify the impregnating solution, and obtain a carpet non-slip pad.

[0043] Comparative Example 1 Mix the emulsion 55%, calcium carbonate 8%, surfactant 0.3%, and the rest of water, and stir them uniformly at high speed. Inject gas during the stirring process. When the viscosity of the slurry is 4.0 x 10 4 mpa·s, stop the stirring, and scrape the slurry on the mesh cloth, and plasticize it at 156℃.

[0044] Comparative Example 2 Add the blowing agent and other additives (vulcanizing agent, emulsifier, antioxidant) into the stirring kettle, and other operations are the same as in Example 1.

[0045] Comparative Example 3 The curing temperature is 150℃, and other operations are the same as in Example 1.

[0046] Comparative Example 4 The emulsifier is 3 parts of sodium dodecyl sulfate, and other operations are the same as in Example 1.

[0047] Performance Test The carpet skid pads prepared in Examples 1-3 and Comparative Examples 1-4 are tested as follows: The static friction coefficient (ASTM-F609), wear and scratch resistance test (ASTM D4966-12(2016)), and resilience test are tested by using an elastic testing machine, and the specific test results are shown in Table 1.

[0048] Table 1 Performance Test Results

[0049] As can be seen from the above table, the static friction coefficient of the carpet skid pad prepared by the method provided by the present application is ≥1.15, mainly because the suitable copolymerization ratio of the synthetic styrene-butadiene emulsion, the styrene segment improves the surface roughness, and ensures the high skid resistance of the product. In addition, from the 500 rpm wear rate, it can be seen that the wear resistance of the product is excellent, which shows that under the action of the vulcanizing agent, the emulsion is firmly attached to the polyester fiber to form a tight three-dimensional network structure, avoiding the emulsion from falling off and improving the adhesion performance. From the resilience, it can be seen that the product has good cushioning performance, the butadiene segment in the synthetic styrene-butadiene emulsion gives excellent elasticity, and the amount of vulcanizing agent is controlled to avoid excessive crosslinking and cause embrittlement, and the wear resistance and cushioning are considered.

[0050] Comparative Example 1 uses the existing formula process: because the mixed base material composed of natural latex and butadiene rubber is used, the skid resistance needs to be improved, and the mesh cloth scraping process cannot form a tight composite structure, and the uneven impregnation leads to a decrease in wear resistance.

[0051] Comparative Example 2: a large number of bubbles are generated due to the early addition of the blowing agent, and the residual bubbles make the composite structure loose, which affects the flatness of the appearance and reduces the elasticity and structural stability.

[0052] Comparative Example 3: The latex film forms rapidly due to high temperature, and the internal bubbles break through the film layer to form protrusions Figure 2 , and the latex aging is accelerated, affecting the surface friction properties and appearance quality.

[0053] Comparative Example 4: Due to the lack of the synergistic effect of non-ionic emulsifiers, the impregnating solution has poor dispersion uniformity, the latex on the fiber surface is unevenly adsorbed, affecting the slip resistance, wear resistance and resilience.

[0054] It can be understood that, for those skilled in the art, equivalent replacements or changes can be made according to the technical solutions and inventive concepts of the present application, and all such changes or replacements shall fall within the protection scope of the present application.
