Embodiment 1～6
[0031] According to the raw material that table 1 provides, prepare thermoplastic elastomer in the following way:
[0032] Step 1. In parts by weight, 40 to 90 parts of matrix resin, 5 to 30 parts of softening plasticizer, 3 to 15 parts of mineral filler, 3 to 15 parts of compatibilizer, 0.2 to 2 parts of lubricant and 0.2 ~0.5 parts of stabilizer are added to the high-speed mixer in turn and mixed evenly, without heating during the mixing process;
[0033] Step 2. Put the homogeneously mixed raw materials in step 1 into a twin-screw extruder, extrude at a temperature of 170° C. to 195° C., and perform stranding, water tank cooling, and granulation in sequence to obtain a thermoplastic elastomer.

Abstract
The invention discloses a thermoplastic elastomer. The thermoplastic elastomer contains the following components in parts by weight: 40-90 parts of matrix resin, 5-30 parts of a softening plasticizer, 3-15 parts of a mineral filling agent, 3-15 parts of a compatilizer, 0.2-2 parts of a lubricating agent and 0.2-0.5 part of a stabilizer. The invention further discloses a preparation method of the thermoplastic elastomer. The preparation method comprises the following steps: sequentially adding the matrix resin, the softening plasticizer, the mineral filling agent, the compatilizer, the lubricating agent and the stabilizer into a high-speed mixer, and uniformly mixing, so as to obtain a mixture; and putting the mixture into a double-screw extruder, extruding at 170-195 DEG C, and sequentially carrying out bar drawing, water tank cooling and granulation, so as to obtain the thermoplastic elastomer. A wood-plastic floor is prepared from the thermoplastic elastomer disclosed by the invention. The thermoplastic elastomer provided by the invention has the advantages of strong coating cohesive force, soft texture, wear resistance, light specific gravity and the like; and furthermore, the prepared wood-plastic floor coated with the thermoplastic elastomer has the functions of shock absorption, skid prevention and noise reduction.
Description
technical field [0001] The invention relates to the technical field of polymer materials, more specifically, the invention relates to thermoplastic elastomers, a preparation method of thermoplastic elastomers, and wood-plastic flooring containing thermoplastic elastomers. Background technique [0002] PE wood-plastic composite material refers to the use of polyethylene instead of the usual resin adhesive, and more than 35% -70% of wood powder, rice husk, straw and other waste plant fibers to form a new wood material, and then extruded, molded, Injection molding and other plastic processing techniques produce plates or profiles. At present, it is mainly used in building materials, furniture and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. Mainly used in wood-plastic interior doors, exterior wall hanging panels, ceilings, decorative wall panels, outdoor floors...
