(2) Mixing an emulsifier and deionized water uniformly, adding methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate and 1/2 amount of initiator, stirring for 10-15 min, adding a flame retardant, dodecafluoroheptyl methacrylate, vinyl triethoxysilane and 1/2 amount of initiator, continuously stirring for 20-30 min, and shearing and emulsifying for 10min to obtain a pre-emulsion;
taking 1/2 of the pre-emulsion, carrying out heat preservation reaction for 10-20 min at 70-75 ℃, adding the rest 1/2 of the pre-emulsion, heating to 80-85 ℃, and carrying out heat preservation for 50-60 min to obtain the organosilicon emulsion;
adding filler and thickener into the organosilicon emulsion, and stirring for 30-40 min at the rotating speed of 1800-2000 r/min to obtain finishing agent;
(3) Taking linen and polyurethane sponge, stacking the outer linen, the polyurethane sponge and the inner linen in sequence, and laminating and compounding by using an adhesive to obtain a pretreated fabric;
and (3) taking the pretreated fabric, finishing the surface of the pretreated fabric by a finishing agent, performing twice soaking and twice rolling, and drying at 80-90 ℃ to obtain a finished product.
In the more optimized scheme, in the step (1), the molar ratio of the material A to the monophenyl fumarate monoacyl chloride to the flame retardant intermediate is 3:1:1.
in the more optimized scheme, in the step (2), the monomers comprise methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate, dodecafluoroheptyl methacrylate and vinyl triethoxysilane, wherein the initiator accounts for 0.5-1% of the total mass of the monomers, and the emulsifier accounts for 2-3% of the total mass of the monomers; the flame retardant accounts for 4 to 6 percent of the total mass of the monomer.
In a more optimized scheme, in the step (2), the filler comprises titanium boride, boron nitride and silicon dioxide, wherein the mass ratio of the titanium boride to the boron nitride to the silicon dioxide is 1:1:2; the emulsifier comprises sodium dodecyl sulfate and span 60, and the mass ratio is 1:1.

According to an optimized scheme, the carpet is prepared according to the preparation method of the environment-friendly wear-resistant automobile carpet.
Compared with the prior art, the invention has the following beneficial effects:
the invention discloses an environment-friendly wear-resistant automobile carpet and a preparation method thereof, wherein linen is used as outer cloth in the preparation process, polyurethane sponge is added into the middle layer to form a sandwich structure of outer linen, polyurethane sponge and inner linen so as to form a composite fabric; because the scheme is used for preparing the automobile carpet, the automobile carpet is required to have excellent wear resistance and waterproof performance, so that the outer cloth is linen with excellent wear resistance and mechanical properties, the middle layer is doped with polyurethane sponge, the elasticity and the comfort in use are improved, and the three materials are laminated and compounded through the adhesive, so that the automobile carpet fabric is formed, and the adhesive is selected as the polyurethane adhesive in actual use.
On the basis of the scheme, in order to further improve the wear resistance and the waterproof performance of the product, the surface finishing process is improved, methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate and dodecafluoroheptyl methacrylate are taken as monomers to be copolymerized, an organosilicon emulsion is obtained through reaction, and then a filler and a thickener are added to prepare the finishing agent, and the water and oil resistance of the carpet can be greatly improved due to the fact that the dodecafluoroheptyl methacrylate and vinyl triethoxysilane are introduced into the finishing agent; meanwhile, the titanium boride and the boron nitride serving as fillers are also introduced into the carpet surface fabric, and the two fillers have extremely high hardness and wear resistance, so that the surface wear resistance of the carpet surface fabric can be ensured.
Further, in order to improve the comprehensive performance of the carpet, the flame retardant is introduced into the finishing agent, and is prepared through the copolymerization of Schiff base bisphenol, a flame retardant intermediate and fumaric acid monobenzoyl ester monoacyl chloride.
In the scheme, as the flame retardant is introduced into the finishing agent and doped during copolymerization of the acrylate monomer and the organosilicon monomer, in order to ensure that the flame retardant can participate in copolymerization, the preparation method defines that the molar ratio of the material A, the monomethyl fumarate monoacyl chloride and the flame retardant intermediate is 3:1:1", under this molar ratio, the hydroxyl in the material A, bisphenol is far beyond the reaction site of flame retardant intermediate, fumaric acid monophenyl methyl ester monoacyl chloride to can be fine with other monomer reaction in the finishing agent, can improve the durability of carpet surface fabric, flame retardant long-term, the practicality is more excellent.
