Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic track materials, in particular to an environment-friendly anti-skid plastic track material and a preparation method thereof. BACKGROUND

[0002] The plastic track is usually formed by mixing granular plastic track material with a binder and then paving on a cement or asphalt ground. The formed plastic track has good flatness, high compressive strength and large friction, and has good anti-skid performance. The formed plastic track has small toxicity, small harm to human health, small influence on the environment and other advantages, which meets the environmental protection needs. In addition, the plastic track is not affected by temperature and humidity, drains quickly, and can be quickly put into use after rain, which is also called all-weather sports ground, and ensures the sports experience of athletes.

[0003] The plastic track material prepared by adding a toughening agent, a filler and a foaming agent to hyperbranched polyethylene as a base material has high anti-skid and wear-resistant performance and excellent mechanical strength. However, the prepared plastic track material has large wear on the plastic track during long-term use, which leads to a decrease in anti-skid performance. By adding an anti-skid and wear-resistant filler, the long-term anti-skid and wear-resistant performance of the plastic track material can be significantly improved. However, the anti-skid and wear-resistant filler has poor compatibility with the plastic track material, which leads to easy agglomeration and precipitation of the anti-skid and wear-resistant filler, thereby affecting the anti-skid and wear-resistant performance of the plastic track. SUMMARY

[0004] The present application provides an environment-friendly anti-skid plastic track material and a preparation method thereof, which solves the problems of poor anti-skid and wear-resistant performance of the plastic track material and poor compatibility of the anti-skid and wear-resistant filler with the plastic track material.

[0005] The technical scheme of the present application is as follows: An environment-friendly anti-skid plastic track material comprises the following raw materials by mass: 50-55 parts of hyperbranched polyethylene, 10-15 parts of anti-skid and wear-resistant filler, 5-8 parts of plastic toughening agent, 45-50 parts of inorganic filler, 1-2 parts of plastic foaming agent and 1-2 parts of dispersant. The anti-skid and wear-resistant filler is obtained by mixing and reacting graphene oxide treated with silane, silane, modified carbon fiber and lauryl methacrylate. The modified carbon fiber is obtained by synthesizing zinc oxide nanosheets on the surface of calcium carbonate particles and then depositing tannic acid on the surface of the carbon fiber. A preparation method of an environment-friendly anti-skid plastic track material comprises the following preparation steps: S1. Hyperbranched polyethylene, anti-skid and wear-resistant filler, plastic toughening agent, inorganic filler, plastic foaming agent and dispersant are uniformly mixed to obtain a mixture. S2. The mixture is extruded and granulated to obtain an anti-skid plastic track material.

[0006] Further, in step S1, the mixing temperature is 60-80℃, the mixing time is 3-10min, and the mixing speed is 600-800r / min.

[0007] Further, in step S2, the extrusion is performed by using a double-screw extruder, the temperature of the extruder barrel and die head is 150-200℃, and the screw rotation speed is 200-500r / min.

[0008] Further, the anti-skid plastic runway material has a particle size of 3-5mm.

[0009] Further, the hyperbranched polyethylene has a degree of branching of 20-25 methyl branches per 1000 carbons and a weight average molecular weight of 100-200 thousand.

[0010] Further, the plastic toughening agent is selected from styrene-ethylene-butylene-styrene block copolymer or styrene-butadiene-styrene block copolymer.

[0011] Further, the inorganic filler is selected from any one of talc, kaolin, and white carbon black.

[0012] Further, the plastic foaming agent is AC foaming agent or ADC foaming agent.

[0013] Further, the dispersant is stearic acid or glycerol stearate.

[0014] Further, the anti-skid wear-resistant filler is prepared by the following steps: A1. Zinc nitrate hexahydrate is added to deionized water, stirred uniformly, heated to 70-80℃, potassium hydroxide and calcium carbonate particles are added, stirred uniformly, dodecyl trimethyl ammonium bromide is added, continued stirring, after standing, filtration, washing, drying, to obtain calcium carbonate particles loaded with nanosheets; A2.

[0015] Further, in the above-mentioned A1 reaction process, the calcium carbonate particles have hydrophilicity, and a large number of hydroxyl groups on the surface of the calcium carbonate particles can combine with zinc ions in zinc nitrate hexahydrate. The zinc ions react with potassium hydroxide to form hydroxide which is deposited on the surface of the calcium carbonate particles. The hydroxide is hydrothermally decomposed at 70°C to form zinc oxide crystals. Dodecyltrimethylammonium bromide as a surfactant is coated on the surface of the zinc oxide crystals to form steric hindrance, control the growth direction of the zinc oxide crystals, and realize the synthesis of petal-shaped zinc oxide nanosheets on the surface of the calcium carbonate particles, thereby obtaining calcium carbonate particles loaded with nanosheets.

[0016] Further, in the above-mentioned A2 reaction process, tannic acid contains a large number of phenolic hydroxyl groups and has good adhesion performance, so that the tannic acid adheres to the surface of the carbon fiber, and then the calcium carbonate particles loaded with nanosheets can be adhered to the surface of the carbon fiber, thereby obtaining the modified carbon fiber.

[0017] Further, in the above-mentioned A3 reaction process, the ultrasonic treatment does not destroy the layered structure of the graphene oxide, so that the silane can be intercalated between the layers of the graphene oxide, and the silicon hydroxyl groups generated by the hydrolysis of the silane can be combined with the oxygen-containing functional groups on the surface and between the layers of the graphene oxide through chemical bonds, thereby maintaining the layered structure of the graphene oxide, realizing the intercalation and surface silanization of the graphene oxide, and obtaining the modified graphene oxide.

[0018] Further, in the above-mentioned A4 reaction process, the silicon hydroxyl groups generated by the hydrolysis of the silane can be combined with the hydroxyl groups on the surface of the modified carbon fiber, so that the silane is grafted on the surface of the modified carbon fiber, thereby endowing the modified carbon fiber with reactive double bonds.

[0019] Further, in the above-mentioned A5 reaction process, azobisisobutyronitrile as an initiator makes the double bonds of the double-bond modified carbon fiber, the double bonds of the surface silane of the modified graphene oxide, and the double bonds of the lauryl methacrylate copolymerize to form a terpolymer, thereby realizing the deposition of the modified graphene oxide on the surface of the modified carbon fiber through the terpolymer, and obtaining the anti-skid and wear-resistant filler.

[0020] Further, in step A1, the mass ratio of zinc nitrate hexahydrate, deionized water, potassium hydroxide, calcium carbonate particles, and dodecyltrimethylammonium bromide is (3-3.4):(90-110):(1.2-1.6):(4-5):(0.3-0.7).

[0021] Further, in step A2, the mass ratio of tannic acid, ethanol, carbon fiber, and calcium carbonate particles loaded with nanosheets is (0.6-1):(45-50):(4-4.5):(2.5-2.9).

[0022] Further, in step A3, the mass ratio of graphene oxide, n-butylamine, toluene and silane is (1.4-1.6):(13-17):(80-90):(3-4).

[0023] Further, in step A4, the mass ratio of modified carbon fiber, silane, ethanol and deionized water is (4-5):(0.6-0.8):(25-30):(8-12).

[0024] Further, in step A5, the mass ratio of double bond modified carbon fiber, modified graphene oxide, lauryl methacrylate, ethanol and azobisisobutyronitrile is (4-5):(3-4):(4-4.5):(130-150):(0.1-0.3).

[0025] Further, the particle size of calcium carbonate particles is 40-60nm.

[0026] Further, the diameter of carbon fiber is 1-2µm, and the length is 8-15µm.

[0027] Further, the flake diameter of graphene oxide is 4-8µm.

[0028] Further, the silane used in step A3 and step A4 is gamma-methacryloxypropyltrimethoxysilane.

[0029] The present application has the following beneficial effects: (1) In the technical scheme of the present application, petal-shaped zinc oxide nanosheets are synthesized on the surface of calcium carbonate particles. On the one hand, the surface of calcium carbonate particles has dense petal-shaped zinc oxide nanosheets, which can exert a "mechanical interlocking" effect, generate greater resistance, improve the friction coefficient, and thus enhance the anti-skid performance of the plastic track material. Moreover, the calcium carbonate particles compounded with zinc oxide nanosheets can form a rough structure on the surface of the plastic track, improving the friction coefficient. On the other hand, the petal-shaped zinc oxide nanosheets have a three-dimensional structure formed by the interlaced connection of nanosheets, which can effectively disperse pressure, reduce local wear, and improve the wear resistance of the plastic track material.

[0030] (2) In the technical scheme of the present application, the calcium carbonate particles loaded with nanosheets are deposited on the surface of carbon fibers through tannic acid. On the one hand, carbon fibers have excellent length-diameter ratio and are randomly distributed in the plastic track material to form a network structure capable of absorbing and weakening external pressure. The thickness of the petal-shaped zinc oxide nanosheets on the surface of the calcium carbonate particles loaded with nanosheets is relatively thin, and the nanosheets are prone to breakage and shedding during long-term use, which affects the anti-skid and wear-resistant performance of the plastic track material. On the other hand, carbon fibers serve as carriers of the calcium carbonate particles loaded with nanosheets, improving the dispersibility of the calcium carbonate particles loaded with nanosheets. Moreover, carbon fibers have high tensile strength and elastic modulus, and when added to the plastic track material, they can significantly enhance the impact resistance and load-bearing capacity of the plastic track, making it less likely to crack or break due to external forces.

[0031] (3) In the technical scheme of the present application, graphene oxide is intercalated and surface silanized with γ-methacryloxypropyltrimethoxysilane, which tightly binds the graphene oxide layers through γ-methacryloxypropyltrimethoxysilane, maintaining the layered structure of graphene oxide and improving the wear resistance of the plastic track material. Moreover, the grafting of γ-methacryloxypropyltrimethoxysilane on the surface of graphene oxide facilitates the covalent grafting of graphene oxide on the surface of modified carbon fibers, producing a micro-ball effect that further enhances the wear resistance of the plastic track material and improves its service life.

[0032] (4) In the technical scheme of the present application, modified graphene oxide is deposited on the surface of modified carbon fibers through a terpolymer. On the one hand, the terpolymer coats the surface of modified carbon fibers, and the interlayer terpolymer acts as a lubricating component, allowing the modified graphene oxide to move back and forth on the surface of modified carbon fibers, producing a micro-ball effect that increases the buffer distance between modified graphene oxide and modified carbon fibers, thereby reducing the heat generated by friction in the composite material and achieving excellent wear resistance. On the other hand, the surface of the anti-skid and wear-resistant filler contains γ-methacryloxypropyltrimethoxysilane molecular chains, which improve the compatibility of the anti-skid and wear-resistant filler with the polyethylene-based plastic track material, enhancing the anti-skid and wear-resistant performance and mechanical properties of the plastic track. In addition, there are numerous gaps between the petal-shaped zinc oxide nanosheets on the surface of modified carbon fibers, allowing the long carbon molecular chains of lauryl methacrylate in the terpolymer to penetrate into the gaps between the nanosheets, forming an entangled network that improves the shear resistance and prevents structural damage to the anti-skid and wear-resistant filler during friction, thereby affecting the anti-skid, wear-resistant performance, and mechanical properties of the plastic track material.

[0057] The anti-skid plastic runway materials prepared in Examples 1-3 and Comparative Examples 1-5 were subjected to performance detection.

[0058] The anti-skid plastic runway materials prepared above had a particle size of 5 mm.

[0059] The anti-skid plastic track material prepared above and PU glue are mixed in a mass ratio of 6:1, stirred uniformly, laid flat, and then pressed to be compacted and bonded to form a coiled material with a thickness of 13 mm and a smooth surface, i.e. an anti-skid plastic track.

[0060] The anti-skid performance, vertical deformation, impact absorption, tensile strength and friction coefficient of the anti-skid plastic track are tested according to the method specified in GB / T 14833-2020 "Synthetic material sports ground surface layer".

[0061] As shown in Table 1 below.

[0062] Table 1 Performance test of anti-skid plastic track material prepared in Examples 1-3 and Comparative Examples 1-5 As can be seen from the data in Table 1, the anti-skid plastic track material prepared in Examples 1-3 has good anti-skid wear resistance and mechanical strength.

[0063] In Comparative Example 1, the anti-skid wear-resistant filler prepared by replacing the calcium carbonate particles loaded with nanosheets with calcium carbonate particles is added to the anti-skid plastic track material, and the anti-skid performance decreases, proving that the petal-shaped zinc oxide nanosheets synthesized on the surface of the calcium carbonate particles can play a "mechanical interlocking" effect, can generate greater resistance, increase the friction coefficient, and thus enhance the anti-skid performance of the plastic track material. The three-dimensional structure of the petal-shaped zinc oxide nanosheets formed by the interlaced connection of nanosheets can effectively disperse pressure, reduce local wear, and improve the wear resistance of the plastic track material.

[0064] In Comparative Example 2, the anti-skid wear-resistant filler prepared by replacing tannic acid with ethanol is added to the anti-skid plastic track material, and the anti-skid performance and mechanical properties decrease, proving that the calcium carbonate particles loaded with nanosheets are deposited on the surface of the carbon fibers by tannic acid, and the carbon fibers form a network structure that can absorb and weaken external pressure, which can avoid the petal-shaped zinc oxide nanosheets with a relatively thin thickness, which are prone to breakage and shedding during long-term use, affecting the anti-skid wear resistance of the plastic track material. In addition, carbon fibers have high tensile strength and elastic modulus, and when added to the plastic track material, they can significantly enhance the impact resistance and load-bearing capacity of the plastic track.

[0065] In Comparative Example 3, the anti-skid wear-resistant filler prepared by replacing modified graphene oxide with graphene oxide is added to the anti-skid plastic track material, and the anti-skid performance decreases, proving that the graphene oxide is intercalated with γ-methacryloxypropyltrimethoxysilane and silanized on the surface, maintaining the layered structure of the graphene oxide and improving the wear resistance of the plastic track material. In addition, it is conducive to the covalent grafting of graphene oxide on the surface of modified carbon fibers, producing a micro-roller effect, and thus enhancing the wear resistance of the plastic track material.

[0066] The anti-skid and wear-resistant filler prepared by replacing the double-bond modified carbon fiber with the modified carbon fiber in Comparative Example 4 is added into the anti-skid plastic track material, and the anti-skid performance and mechanical properties thereof are reduced, which proves that the double-bond modified carbon fiber can copolymerize with the modified carbon fiber and lauryl methacrylate, so that the modified graphene oxide is coated on the surface of the modified carbon fiber through the terpolymer, the terpolymer between the layers acts as a lubricating component, so that the modified graphene oxide moves back and forth on the surface of the modified carbon fiber, generates a micro-rolling ball effect, increases the buffer distance of the modified graphene oxide and the modified carbon fiber, and thus reduces the heat generated by friction of the composite material, and has excellent wear-resistant effect.

[0067] The anti-skid and wear-resistant filler prepared by replacing lauryl methacrylate with ethanol in Comparative Example 5 is added into the anti-skid plastic track material, and the anti-skid performance and mechanical properties thereof are reduced, which proves that the long carbon molecular chain of lauryl methacrylate in the terpolymer can penetrate into the gap between the nanosheets, form an entangled network, and improve the shear resistance, so as to avoid the structure damage of the anti-skid and wear-resistant filler caused by strong shear force during friction, and affect the anti-skid, wear-resistant performance and mechanical properties of the plastic track material.
