Abstract

The invention relates to a high-gloss oil-resistant styrene resin and a preparation method and application thereof, belonging to the technical field of modified resins. The high-gloss oil-resistant styrenic resin comprises the following formula by weight: 100 parts of general-purpose polystyrene, 5-20 parts of toughening agent I, 5-15 parts of toughening agent II, 0.5-0.5 parts of oil-resistant modifier 5 parts, 0.1-1 part of antioxidant, 0.1-1 part of lubricant. Compared with the prior art, the styrene-based resin prepared by the invention greatly improves the oil resistance of the material on the basis of ensuring high impact and high gloss, and can be directly applied to extruded refrigerator liner materials.

Description

technical field [0001] The invention relates to a modified resin, in particular to a high-gloss oil-resistant styrene resin and a preparation method and application thereof. Background technique [0002] Styrene resins are often used in extrusion-molded refrigerator panels after impact resistance modification. Age and appearance of refrigerator panels. [0003] Commonly used methods to improve the oil resistance of impact styrene resins are as follows: (1) Use HIPS (high impact strength polystyrene) with large particle size. Generally, when the particle size is above 6um, the oil resistance of the material will decrease. Significantly improved; (2) HIPS and low-density polyethylene or copolymerized polypropylene are used to make alloys, and the oil resistance of polyolefins is used to improve the oil resistance of alloys. Chinese patent CN 104098865A discloses a method of alloying HIPS with low-density polyethylene or copolymerized polypropylene, which consists of 500-800 ...
