Antibacterial wear-resistant runway floor composite material and preparation method thereof

Abstract

The invention discloses an antibacterial wear-resistant runway floor composite material which comprises the following components in parts by weight: 0.5-2 parts of an ultraviolet stabilizer, 0.2-1 part of an antioxidant, 10-30 parts of a reinforcing agent, 2-10 parts of antibacterial composite microspheres, 50-80 parts of a base material, 1-5 parts of a dispersing agent and 2-7 parts of a cross-linking agent. Melting, mixing, extruding and granulating are performed by adopting double screws or three screws, so as to obtain the antibacterial and wear-resistant composite material for the track spliced floor. The runway spliced floor composite material prepared by the method has good long-acting self-cleaning and antibacterial properties, wear resistance and impact resistance, good ultraviolet resistance and aging resistance and good fireproof and flame-retardant properties, and a spliced floor with a personalized complex structure can be produced by adopting a 3D printing manufacturing and forming process.

Description

technical field [0001] The invention relates to the field of runway splicing floor composite materials, in particular to an antibacterial and wear-resistant runway floor composite material and a preparation method thereof. Background technique [0002] At present, the types of flooring and flooring materials are very wide and varied, and the common ones are pure wood materials, wood-plastic composite materials, and functional plastic composite materials. According to different application environments, there will be various corresponding materials. At present, most floor materials on the market are mostly used indoors, and there are few applications or researches on outdoor flooring. Nowadays, splicing floors for outdoor sports tracks are often obtained by injection molding of conventional materials or composite materials. Therefore, this type of runway floor will lack some necessary functions, or the required performance effect is not very good, such as insufficient wear r...

[0003] Chinese patent (patent number: CN201910506465.7) discloses a preparation method of water-resistant plastic flooring materials. Its composition characteristics and preparation steps are: weighing polyvinyl chloride, modified porous calcium carbonate, and dioctyl terephthalate 1. Put dioctyl adipate into the internal mixer, banbury at 180-200°C for 20-30 minutes, and then discharge to obtain the water-resistant plastic flooring material. The porous calcium carbonate is passed through calcium nitrate solution, polyethylene oxide After the reaction of alkane and sodium carbonate solution, centrifuge to obtain a precipitate and dry it in an oven at 105-110°C for 1-2 hours. The modified porous calcium carbonate is separated by shaking and impregnating porous calcium carbonate and tetramethylsiloxane Finally, it is mixed with allyl epoxy polyether, chloroplatinic acid and isopropanol, stirred and reacted under nitrogen protection, and then washed and dried; however, its wear resistance and runway application requirements are insufficient, and PVC is used outdoors Exposure to the sun for a long time will slowly cause discoloration and decompose unhealthy gases such as hydrogen chloride, so it is not suitable for the application of the runway

[0005] Chinese patent (patent number: CN202011438257.7) discloses a flame-retardant PVC / NBR rubber-plastic floor material and its processing method. Its composition features include PVC 40-60 parts, NBR 30-50 parts, reinforcing carbon black 5 -20 parts, 5-20 parts of epoxy soybean oil, 1-10 parts of superfine flame retardant, 1-10 parts of antioxidant, 1-10 parts of ultraviolet absorber; the matrix material PVC and NBR are mixed and prepared The cold resistance of the obtained material is not good, so it is not suitable for use in some colder environments such as the north
