Description
Technical field
The present invention relates to a kind of polystyrene alloy material, specifically, relate to a kind of solvent-resistance polystyrene ternary alloy material for refrigerator inner liner plates, its preparation method and application thereof.
Background technology
(English is Polystyrene to polystyrene, be called for short PS) be a kind of water white thermoplastics, high-impact polystyrene is by add a kind of shock proof polystyrene products that poly-isoprene-isobutylene rubber particulate way is produced in polystyrene, opaque and slightly be white in color, this polystyrene products are by adding the micron order rubber grain and the way by scion grafting links together polystyrene and rubber grain.
A distinct disadvantage of polystyrene is exactly that solvent resistance is poor, can be by multiple organic solvent dissolution, and can be corroded not anti-grease by strong acid and strong base.
Everybody is familiar with refrigerator, can be for the making material of inner container of icebox, people know little about it, and refrigerator inner liner plates requires to have very high solvent resistance, lower temperature resistance and shock resistance, this particular requirement of refrigerator plate causes raw material production technical sophistication, production difficulty big.
Inner container of icebox is after sheet material is extruded into sheet material, plastics sucking moulding is the required shape of inner bag, form a cavity with outside stainless steel casing, the processing of in cavity, foaming then, make in the cavity of foam layer injection between stainless steel casing and inner bag of loose insulation, reach the purpose of insulation.
Because the freonll-11 CFC that the conventional refrigerator production adopts is after the atmosphere high-altitude is gathered, by a series of photochemical degradation reactions, produce chlorine radical and destroy the high-altitude ozonosphere, promptly produce so-called " ozonosphere black hole " phenomenon and cause ozonosphere to keep out ultraviolet ability drop even forfeiture, therefore international environmental protection organization has cancelled the application of freonll-11, use pentamethylene C5 replacement fluorine Leon instead, but because the pentamethylene boiling point is lower, according to the manufacturing equipment actuality of present refrigerator, can't accomplish all to use pentamethylene, the actual greatly chlorodifluoroethane HCFC141b that replaces with through the approval of international environmental protection organization, yet HCFC141b p-poly-phenyl ethene, there is very big erosion action in ABS, and foamed material is to be dissolved in pentamethylene C5 and these organic solvents of fluorine ethylene dichloride HCFC141Bz, solvent in foaming process and later over a long time in remaining solvent can cause erosion to inner liner plates, the physical strength and the toughness of inner liner plates have been weakened, can use the softening forfeiture of the refrigerator inner liner plates necessary function of these material produce, thereby jeopardize final user benefit, therefore cause refrigerator inner liner plates to become chemical resistance, promptly solvent resistance requires very strict.
Present most of refrigerator producer adopts the method for the ABS extrusion board of strengthening solvent resistance.ABS is formed by vinylbenzene, the copolymerization of acrylonitrile and butadiene serum, thermotolerance own and solvent resistance are good than polystyrene all, and has glossiness, the ratio content of general vinyl cyanide is higher, its thermotolerance, rigidity and solvent resistance are better, and what wherein extensively adopt is exactly strange beautiful Polylac (R) the ABS series in Taiwan.
Regular grade ABS solvent resistance is poor, in order to adapt to the solvent resistance requirement of inner liner plates, need to adopt the ABS that strengthens solvent resistance, this ABS designs at the environment of the high solvent resistance of needs specially, kind is few, output is little, and price is very high, and general price is between 17000～18000 yuan/ton, higher 3000～4000 yuan than polystyrene price per ton, cause the material cost of refrigerator inner liner plates high, source of goods instability, Lead Time is long.
If improve the solvent resistance of polystyrene, adopt the home-made polystyrene to produce the material of refrigerator inner liner plates, the inner container of icebox material cost be can reduce greatly, and the competent source of goods and quick response Lead Time guaranteed.
Therefore improve the solvent resistance of polystyrene, the polystyrene products of developing solvent resistance seem very urgent.
Because the molecular structure and the characteristic of polystyrene and these two kinds of polymkeric substance of polyethylene itself differ greatly, cause this two kinds of high molecular polymers, under the effect that does not have compatilizer and chemical polarity key, the two is inconsistent, this point from the difference of the solubility parameters of the two also as can be seen, the solubility parameters of polystyrene is 8.9～9.4, poly solubility parameters is 7.24, the difference of the two is more than 1.5, and according to compatible thermodynamic principles, the two is incompatible on thermodynamics.
CN 1563166A discloses a kind of Anti-141b Polystyrene Refrigerator Lining Material, and this material is mainly by polystyrene 15～50%; Polyethylene 23～58%; Compatilizer (polycthylene grafted cis-butenedioic anhydride or superoxide) 7～13%; Nucleator 5～13%; Rubber elastomer 9.3～11.3%; Polyethylene wax 0.2～0.5%; Zinic stearas 0.1～0.3%; Oxidation inhibitor 0.1～0.2% is formed.Though this inner lining material can improve solvent resistance equally, but prescription more complicated, also increased production cost to a certain extent, there is the smell of irritating cis-butenedioic anhydride resistates in the compatilizer of grafting class in melted by heating extruding pelletization and extrusion board, and in fact consistency is also unstable owing to the instability of the percentage of grafting of grafts causes.
