The bottom layer 5 comprises 100 parts of PVC, 37 parts of DOTP, 200 parts of heavy calcium carbonate, 3 parts of foaming regulator, 5 parts of pigment, 0.4 part of PE wax and 5 parts of calcium zinc stabilizer.
DOTP is an organic compound, is a primary plasticizer with excellent performance for PVC plastics, has the advantages of heat resistance, cold resistance, difficult volatilization, extraction resistance, softness, good electrical insulation performance and the like compared with common diisooctyl phthalate (DOP), and shows excellent durability, soapy water resistance and low-temperature softness in products.
Calcium carbonate is widely used in filling polyvinyl chloride PVC resin, and the addition of calcium carbonate plays a role in improving the performance of PVC products to expand the application range thereof, and in plastic processing, the calcium carbonate can reduce the shrinkage rate of the resin, improve the flow change, control the viscosity, and also play a role in improving the dimensional stability of plastic products, improving the hardness and rigidity of the plastic products, improving the processability of the plastic products, improving the heat resistance of the plastic products and reducing the cost of the plastic products.
The foaming regulator is used for improving the pressure and torque of the PVC melt, so that the cohesion and homogeneity of the PVC melt are effectively improved, and the obtained PVC product is more compact.
The PE wax can increase the gloss and processability of the product, is used as a lubricant, has stable chemical property and good electrical property, enhances the plasticizing degree, reduces the friction force between materials and between the materials and the surface of processing equipment, thereby reducing the flow resistance of the melt, reducing the viscosity of the melt, improving the fluidity of the melt, avoiding the adhesion of the melt and the equipment, improving the surface smoothness of the product, and the like, and prevents the melt from sticking to rollers in the processing of calendaring.
The calcium-zinc stabilizer is synthesized by adopting a special compounding process by taking calcium salt, zinc salt, lubricant, antioxidant and the like as main components, can replace toxic stabilizers such as lead-cadmium salts, organic tin and the like, has quite good thermal stability, light stability, transparency and tinting strength, and has the advantages that in PVC products, the processing performance is good, the thermal stability is equivalent to that of lead salt stabilizers, and the calcium-zinc stabilizer is a good nontoxic stabilizer, and can endow PVC mixture with good uniform plasticization and high-speed melt fluidity, so that the surface of the products is smooth.
The inner stabilizing layer 4 comprises glass fiber felt and polyvinyl chloride paste resin, and the mass of the glass fiber felt is 20-55g/m 2 。
The glass fiber felt is a non-woven fabric formed by interweaving glass fiber monofilaments into a net shape and solidifying the non-woven fabric by using a resin binder, has the advantages of flat surface, good dimensional stability, good uniformity and good thermal strength, and can obviously improve the phenomena of thermal expansion and cold contraction of the pvc floor and increase the silencing effect due to the fact that the traditional pvc floor is poor in thermal expansion resistance and the net-shaped glass fiber felt is added into the pvc floor.
The polyvinyl chloride paste resin is used as an adhesive, and has the advantages of low cost of processing equipment, simple and cheap die, special shape, easy foaming, less heating times of products and small quantity and multiple varieties of production.

Polyethylene can be classified into high-density polyethylene and low-density polyethylene according to the polymerization method, the molecular weight and the chain structure, has good flexibility, extensibility, electrical insulation, transparency, easy processing property and certain air permeability, and has good chemical stability, alkali resistance and general organic solvent resistance.
Azodicarbonamide is an organic compound, and a foaming agent commonly used in industry can be used for the production of yoga mats, rubber soles and the like so as to increase the elasticity of products.
Dicumyl peroxide is a strong oxidant, can be used as an initiator for monomer polymerization, and can be used as a vulcanizing agent, a cross-linking agent, a curing agent and a flame retardant additive for high polymer materials, and can play a role of the cross-linking agent in the processing process of producing the mute layer 6.
Zinc oxide is widely used in the manufacture of plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointments, adhesives, foods, batteries, flame retardants and the like, so that the silence layer 6 has good corrosion resistance, tear resistance and elasticity.
Zinc stearate mainly acts as a lubricant.
A preparation method of a high-stability mute glass fiber felt floor comprises the following steps:
s1, manufacturing a middle layer 3 and a bottom layer 5: mixing the middle layer raw materials in a mixer, putting the mixed raw materials into an internal mixer for banburying, and calendaring to prepare a sheet-shaped semi-finished product, wherein the manufacturing method of the bottom layer 5 is the same as that of the middle layer 3;
s2, manufacturing an inner stabilizing layer 4: cutting the glass fiber felt layer according to the product size, and uniformly coating the adhesive on the surface of the glass fiber felt;
s3, manufacturing a mute layer 6: mixing the raw materials of the mute layer together, putting the mixture into a mixing mill for heating and stirring, putting the mixture into an extruder for extruding after the mixture is finished, cooling and foaming the extruded polyethylene foam material through a die, and cutting and forming the foamed polyethylene foam material;
