In the present invention, it has been found that using dimethyl ethenyl acetenyl hydroperoxides modified polypropene conduct
The elastic rubbery body of TPV, can enhance the encapsulated damage resistant ability in floor, and possible reason is dimethyl ethenyl acetenyl
Hydroperoxides modified polypropene can reduce encapsulated surface tension, so that the coefficient of friction for reducing encapsulated surface changes to reach
The effect of the scratch resistant performance of kind material surface.
In order to achieve the effect that enhance scratch resistant performance, need to reduce the skin-friction coefficient of cover material, however in day
Often in life, after reducing skin-friction coefficient, user is when in use it is possible that easy the problems such as slipping, therefore, inventor
It joined carbon fiber in the cover material of floor to be modified the entire floor TPV cover material, not by the distinctive structure of carbon fiber
But the water-resistant capacity of whole system can be enhanced, can more enhance skin-friction coefficient, utilize dimethyl ethenyl acetenyl hydrogen peroxide
The reasonable compounding of compound modified polypropene and carbon fiber can enhance the encapsulated damage resistant ability in floor and enhance surface
Coefficient of friction.However inventor has found in research and development, not arbitrary addition is all up double effects, only in caoutchouc elasticity
The weight ratio of body and fibrous material is (1-3): when (1-2), can overcome technology resistance.
For floor, formaldehyde can be contained during fabrication and installation, common floor glue can only be from the one of floor
Face prevents, over time, formaldehyde being come out from the gap on side floor slowly, chronic hazard the body of people
Body health.Polyester fiber is the synthetic fibers as made of binary acid and dihydric alcohol polycondensation, abbreviation PET fiber.On the one hand, of the invention
In by addition polyester fiber, during copolymerization, between polyester fiber, carbon fiber and modified polypropene rubber elastomer
It entwines mutually, to form a fine and close network structure, zero volatilization of formaldehyde can be ensured in terms of front and side two.
In addition, fine and close structure also effectively prevents the absorption and volatilization of moisture in floor, thus the wet rate that rises of the drying shrinkage for reducing floor,
The stabilization for maintaining ground plate bulk, significantly extends the service life on floor.Apply also being found surprisingly that, when control caoutchouc elasticity
The weight ratio of body and fibrous material is that 2:1 can be perfect when the weight ratio of carbon fibre material and Polyester Fibers is 1:2
Solve the problems, such as that the encapsulated stickiness between floor paint in the floor as caused by the special construction of carbon fiber is not fine, possibility
The reason of be, the weight ratio of rubber elastomer and fibrous material be 2:1, the weight ratio of carbon fibre material and Polyester Fibers
When for 1:2, it is copolymerized each other, the group in molecule can be with main matter polyurethane resin and epoxy resin in floor paint
Between have an effect power, to enhance the encapsulated adhesive force between floor paint in the floor TPV, so as to avoid due to solarization and
The migration of caused floor paint small molecular, and the case where gradually floor paint is caused to crack.
Hydrophilic surface than hydrophobic surface more resistant to dirt, it is encapsulated for general floor for, hydrophobic effect is preferably
Plate cover material anti-pollution characteristic is worse, and the preferable floor cover material hydrophobic effect of anti-pollution characteristic is poor, and the present invention can solve
Certainly resistant and hydrophobic contradiction, the reason is that because the dimethyl ethenyl acetenyl hydroperoxides used in the present invention are modified poly-
Propylene has hydroxyl again while with alkylene, therefore can enhance the antistatic effect on the floor TPV cover material surface,
So that the present invention have both it is extremely hydrophobic and extremely resistant the effect of.
In a particular embodiment, each temperature setting of the Screw Extrusion is 170-175 DEG C of feeding section, leading portion 195-
198 DEG C, 185-190 DEG C of middle section, 180-185 DEG C of back segment temperature；In a preferred embodiment, each temperature of the Screw Extrusion is set
It is set to 170-174 DEG C of feeding section, 196-197 DEG C of leading portion, 186-189 DEG C of middle section, 181-184 DEG C of back segment temperature；Further
In preferred embodiment, each temperature setting of Screw Extrusion be 173 DEG C of feeding section, 196 DEG C of leading portion, 187 DEG C of middle section, back segment
183 DEG C of temperature.
