Problems solved by technology

[0002] At present, there are many types of flooring in home decoration materials. According to the classification of materials, they mainly include: solid wood flooring, laminated wood flooring, solid wood composite flooring, bamboo wood flooring, cork flooring, etc. However, whether it is solid wood flooring, composite flooring or bamboo wood flooring They are not moisture-proof, they are easy to swell and cause deformation when exposed to water, and there will be problems such as mildew when used for a long time in places with large humidity changes
At present, there is a new type of floor material in the home improvement market - plastic wood floor, which has both the water resistance and corrosion resistance of plastic and the texture of wood. The service life can reach more than 10 years, and it is not easy to crack, fade, and absorb moisture. When the wood content in the plastic wood floor is too much, it will easily lead to poor load capacity and wear resistance can not meet the demand

Abstract

The invention discloses a preparation method of a wood-plastic floor with high load. The preparation method comprises steps as follows: polypropylene granules are fed into a mixer, heated and stirred, talcum powder, calcined clay, a titanate coupling agent, chlorinated paraffin, a lubricant, an ultraviolet absorber and an antioxidant are added and continuously stirred, and a prefabricated material is obtained; the prefabricated material and wood meal are mixed uniformly and fed into an extruder, ceramic fibers and nylon fibers are fed into the extruder through a side feeding port in the extruder, a mixture is subjected to blending and extrusion molding, and the wood-plastic floor with high load is obtained. Modified chitosan is prepared with a process comprising steps as follows: chitosan is dissolved in an aqueous citric acid solution, pH of the aqueous citric acid solution is 3-4, ammonium persulfate is added, a mixture is heated and stirred, pH of a system is regulated to 10-11 with sodium hydroxide, temperature is reduced, ethylene oxide is dropwise added and stirred, freeze drying is performed, polyvinyl alcohol and oxalic acid are added and mixed uniformly, taurine is added, a mixture is heated, stirred and dewatered, and modified chitosan is obtained.
