Problems solved by technology

Although the lining material can also improve solvent resistance, the formula is relatively complicated, which also increases the production cost to a certain extent. The grafted compatibilizer is irritating when it is heated, melted, extruded, granulated and extruded. The odor of the maleic anhydride residue, and the compatibility is actually unstable due to the instability of the grafting rate of the graft

Abstract

The invention provides a solvent-resistance polystyrene ternary alloy material used for refrigerator inner liner plates. The solvent-resistance polystyrene ternary alloy material comprises 20 to 65 percent of high-impact polystyrene, 15 to 60 percent of linear low-density polyethylene, 5 to 25 percent of ethane-butadiene-styrol copolymer compatilizer, 0.1 to 0.6 percent of antioxidant and 0.1 to 0.6 percent of calcium stearate. The invention also provides a preparation method and an application of the alloy material. The polyethylene has excellent solvent-resistance, the polystyrene has good mechanical strength, and the invention enables the polyethylene and the polythene to be mixed into an interpenetrating network structure through a special solvent polymer to form stable polymer alloy, therefore, the invention not only retains the mechanical property of the polystyrene but also has the excellent solvent-resistance of the polyethylene simultaneously, the solvent-resistance polystyrene product widely applied to the refrigerator inner liner plates is obtained, the material cost of the refrigerator inner liner plates is reduced, and the refrigerator inner liner plate material with stable supply of goods and quick delivery is provided.

Description

technical field [0001] The invention relates to a polystyrene alloy material, in particular to a solvent-resistant polystyrene ternary alloy material for a refrigerator liner plate, a preparation method and application thereof. Background technique [0002] Polystyrene (Polystyrene in English, referred to as PS) is a colorless and transparent thermoplastic. High-impact polystyrene is an impact-resistant polystyrene produced by adding polybutyl rubber particles to polystyrene. Styrene products are opaque and slightly white. This polystyrene product is connected with polystyrene and rubber particles by adding micron-sized rubber particles and grafting. [0003] An obvious disadvantage of polystyrene is that it has poor solvent resistance, can be dissolved by a variety of organic solvents, and will be corroded by strong acids and alkalis, and is not resistant to grease. [0004] Everyone is familiar with refrigerators, but little is known about the materials used to make refri...
