Description
Technical field
The invention belongs to square carpet back lining materials and preparation field thereof, particularly a kind of environmental protection square carpet back lining materials and preparation method thereof.
Background technology
What used in present square carpet market at present commonly used mainly is PVC and pitch.PVC backing carpet is because of having very strong corrosion protection, characteristics such as mothproof, antistatic, fire-retardant, and life-time service can warpage yet, distortion, for masses like.But can produce deleterious flue gas during the PVC burning, receive the criticism of international green peace organization; The pitch backing have the callable benefit of environmental protection and this material cheap, therefore more in vogue abroad, but should carry on the back at the end receive winter and summer the temperature difference influence have the drawback of contraction aspect, and blanket face or the metope do not made dirty of taking every caution against error when mating formation; Density the best of urethane backing, good stability, visual appearance are near PVC, but this method processing cost is high, and producer seldom adopts both at home and abroad.Go back some new backing ME in addition, but it not very optimistic on the feature of environmental protection and enterprise cost.Given this, need the new square carpet back lining materials of research and development.
Summary of the invention
Technical problem to be solved by this invention provides a kind of environmental protection carpet backing material and preparation method thereof, and raw materials used environmental protection is all pollution-free to environment for use and user, and the back lining materials good mechanical properties that makes surpasses national standard; Preparing method's technology is simple, is fit to industrial mass production.
A kind of environmental protection square carpet back lining materials of the present invention; Its component comprises: the atactic polypropylene(APP) APP of the terpolymer EP rubber EPDM of 14～22wt%, the hp-ldpe LDPE of 34～58wt%, 14～22wt% is as body material, the CaCO of 14～22wt%
3As weighting agent.(lime carbonate, Chemical Reagent Co., Ltd., Sinopharm Group, commercially available; Atactic polypropylene(APP) (APP), Qingdao Bang Ni ltd, commercially available; High pressure low density polyethylene (LDPE) (LDPE), the good imperial industrial chemicals in Shanghai ltd, commercially available; Terpolymer EP rubber (EPDM), the wide trade Co., Ltd of Shanghai glue, commercially available)
The preparation method of a kind of environmental protection square carpet back lining materials of the present invention comprises:
(1) mixing: as the roller temperature on the two roll plastic mixing mill to be remained on room temperature, between roller, add the terpolymer EP rubber EPDM of 14～22wt%, the hp-ldpe LDPE of 34～58wt%, the atactic polypropylene(APP) APP of 14～22wt%, the CaCO of 14～22wt% respectively
3, mixing 20～40 minutes, make each component mixing even, after the mixing end batch mixing is stripped down from roller, shred then and process mixing particle;
(2) fusion: above-mentioned mixing particle is layered in the watch-glass equably, under 220～230 ℃ of conditions, heated 3～5 minutes, make the abundant fusion of mixing particle;
(3) be shaped: the mixing particle of fused is coated in the carpet dorsal part equably, carpet is placed mould, mould is all clamped with steel plate up and down, and between steel plate and mould with lay one deck polytetrafluoroethylene film prevent to make dirty carpet and backing; Steel plate is moved into vulcanizing press, and pressurization is 1～3 minute under the pressure of 3～5MPa; Take off steel plate, the demoulding makes the square carpet with the environmental protection back lining materials.
EPDM in the said step (1): LDPE: APP: CaCO

EPDM in the said step (1): LDPE: APP: CaCO
3Mass percent is 22%: 34%: 22%: 22%.
Random polypropylene (APP) is the by product when synthesizing polypropylene in the plastics industry, and APP has the visco-elasticity of rubber like at normal temperatures, but molecular weight is little, the MWD broad, and good fluidity is difficult for causing the shearing crystallization.New LDPE (film grade) (LDPE) is mainly used in general consumable material such as film, wrapping material, protective material and the relevant consumer's goods and the industrial goods of life.Terpolymer EP rubber (EPDM) is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, and the topmost characteristic of EPDM is exactly its superior antioxidant, anti-ozone and erosion-resistant ability.Because terpolymer EP rubber belongs to polyolefine family; It has fabulous vulcanization characteristics, and in the middle of all rubber, EPDM has minimum proportion; It can absorb a large amount of fillers with oil and little to itself performance impact, rubber compound that therefore can low preparation cost.Above selected materials all be compliance with environmental protection requirements nontoxic, material has no side effect.
Beneficial effect
(1) the raw materials used environmental protection of the present invention, all pollution-free to environment for use and user, the back lining materials good mechanical properties that makes surpasses national standard, can be widely used in places such as family, hotel, business offices;
(2) preparing method's technology of the present invention is simple, is fit to industrial mass production.
