Abstract
The invention discloses a method for preparing a material for making door liners of liners of refrigerators and freezers. The key points of the technical scheme of the invention include: selecting polystyrene, polyethylene, polypropylene, stabilizer, antioxygen, lubricating agent and pigment; stirring the materials in part by weight in a high-speed stirring machine; extruding the stirred material in a double-screw unidirectional parallel plastic extruder; cooling the extruded material; and thus obtaining the material. In the invention, the production cost is low, the processing process is simple, and the material disclosed by the invention has high impact strength, high mechanical performance, high corrosion resistance, high tear resistance, high flame-retarding performance, high tensile strength, high-temperature resistance and low-temperature resistance.
Description
Technical field:
The present invention relates to novel material, the particularly a kind of inner bag of refrigerator, refrigerator-freezer and proprietary material of door courage of being applicable to.
Background technology:
Modern various household electrical appliance particularly all adopt ABS, HIPS material like employed inner bags such as refrigerator, refrigerator-freezer, door courage, and its complete processing is complicated, and production cost is higher; Inner bag, door courage like present refrigerator, refrigerator-freezer generally adopt import or homemade ABS, HIPS material, need be processed into refrigerator, the inner bag of refrigerator-freezer, the door courage of different model before the assembling, are fixed on refrigerator, refrigerator-freezer inside then, foaming and setting.Use above-mentioned ABS, HIPS material, in case the product processed moulding is difficult for change; In addition, tankage such as edges of boards utilize cumbersome again, and ABS material edges of boards tankage also exist with other material not to be allowed, and is difficult to problems such as recovery.Because for the inner bag of refrigerator, refrigerator-freezer, door courage, generally do not stress, material therefor does not need very high intensity in fact.And the price of ABS, HIPS is higher, and reason is: because the intensity of these materials is higher, complete processing is complicated, has increased its manufacturing cost.
Summary of the invention:
The purpose of this invention is to provide a kind of cost low, process the preparation method of refrigerator ice cabinet inner bag door courage proprietary material easily.Technical scheme of the present invention is that a kind of preparation method of refrigerator ice cabinet inner bag door courage proprietary material is characterized in that: choose PS 100-110 weight part; Vilaterm 15-25 weight part; Vestolen PP 7052 10-20 weight part, stablizer 3-4 weight part, oxidation inhibitor 0.7-0.9 weight part; Lubricant 0.075-0.09 weight part, pigment 0.06-0.07 weight part; Each material of above-mentioned weight part is put into impeller; Stirred 3-6 minute, whipping temp 10-20 ℃, the material after will stirring again is by two bar cocurrent and parallel plastics extruders; Body temperature: 180～210 ℃; Head temperature: 190～210 ℃, the material after extruding cools off at the water by 30～60 ℃ of water temperatures, makes the present invention.Described stablizer is a Zinic stearas; Described oxidation inhibitor be three monooctyl esters or three the last of the ten Heavenly stems fat; Described lubricant is solid paraffin or Triple Pressed Stearic Acid; Described pigment is ultramarine.Production cost of the present invention is lower, and complete processing is simple, and material according to the invention has high impact strength and good mechanical property also has erosion resistance, resistance to tearing and flame retardant resistance, and good He high temperature resistant, the low temperature resistant advantage of tensile strength.
