As preferably, described softening agent adopts dioctyl terephthalate.
As preferably, described stablizer adopts calcium-zinc composite stabilizing agent.
As preferably, described middle material density is 2050kg/m3, and hardness is (Shore durometer) D=65; With wearing layer, the rate of expansion of printing the compound rear product of color film, underlying material heat be 0.085%, shrinking percentage is 0.05%.
The present invention adds appropriate paracril in the formula of original middle material, adopt consistency and paracril self fabulous between paracril (NBR) and polyvinyl chloride (PVC) to draw high intensity, thermotolerance, winter hardiness, thereby the physicals that improves PVC goods, makes the physicals of product more outstanding.
The present invention also provides a kind of preparation method of the middle material for latch floor, and described method is as follows:
By the high-speed stirring mixing according to the above ratio of material pvc, softening agent, stablizer, by self-friction, be heated to 70-80 ℃, allow polyvinyl chloride fully absorb softening agent, and stablizer is evenly distributed, do not emit compound; Add calcium carbonate to continue to mix, do not emit compound; Add paracril and carbon black to continue to mix, compound after blend is sent in Banbury mixer, 170 ~ 180 ℃ of Banbury mixer temperature controls, banburying discharging in 4 minutes, by mill rolling out film, 135 ℃, 130 ℃, 140 ℃ of mill temperature controls, compound in mill by self-friction heating to 155 ℃, 150 ℃, 160 ℃, while opening refining, by the automatic stirring of tripper, while guaranteeing out refining, material mixing is more even; Cooling shaft by 25 ~ 40 ℃ of 9 temperature controls during slice is quickly cooled to room temperature by middle material.What the present invention finally added paracril is because the oil absorbency of paracril is more eager to excel in whatever one does than polyvinyl chloride.
As preferably, described softening agent adopts dioctyl terephthalate.
As preferably, described stablizer adopts calcium-zinc composite stabilizing agent.
The present invention is claimed a kind of floor also, comprises wearing layer, prints color film, initial bed and the middle bed of material, and the described middle bed of material adopts above-mentioned middle material to make.
The present invention, owing to having adopted above technical scheme, has significant technique effect:
The present invention, in preparing the method for middle material, in the situation that strengthening inorganic filler, adopts and adds paracril, and convenient opening refined processing, when having improved the toughness of middle material, also improved snap close between product and drawn intensity of force.
Compare with existing plastic floor, middle material prepared by the present invention and wearing layer, print the flooring product that color film, underlying material heat obtains after compound and there is intensity, thermotolerance, winter hardiness.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
embodiment 1
For a middle material for latch floor, by the raw material of following weight part, made:
100 parts of polyvinyl chloride, 2 parts of stablizers, 36 parts, softening agent, 0.5 part of carbon black, 510.6 parts, calcium carbonate, 7 parts of paracrils.Wherein, softening agent adopts dioctyl terephthalate; Stablizer adopts calcium-zinc composite stabilizing agent.
The preparation method of the above-mentioned middle material for latch floor is as follows:
By the high-speed stirring mixing according to the above ratio of material pvc, dioctyl terephthalate, calcium-zinc composite stabilizing agent, by self-friction, be heated to 70-80 ℃, allow polyvinyl chloride fully absorb dioctyl phthalate, and calcium-zinc composite stabilizing agent is evenly distributed, do not emit compound; Add calcium carbonate to continue to mix, do not emit compound; Add paracril and carbon black to continue to mix, compound after blend is sent in Banbury mixer, 170 ~ 180 ℃ of Banbury mixer temperature controls, banburying discharging in 4 minutes, by mill rolling out film, 135 ℃, 130 ℃, 140 ℃ of mill temperature controls, compound in mill by self-friction heating to 155 ℃, 150 ℃, 160 ℃, while opening refining, by the automatic stirring of tripper, while guaranteeing out refining, material mixing is more even; Cooling shaft by 25 ~ 40 ℃ of 9 temperature controls during slice is quickly cooled to room temperature by middle material.
