Description

A kind of refrigerator ice cabinet inner bag door courage preparation methods
Technical field:
The present invention relates to novel material, particularly a kind of refrigerator ice cabinet inner bag door courage preparation methods.
Background technology:
At present, the inner bag of various household electrical appliance such as uses such as refrigerator, refrigerator-freezer, door courage all adopt simple ABS, HIPS material, and complete processing is complicated, and production cost is higher.Like present refrigerator, refrigerator-freezer inner bag, door courage, 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, be fixed on refrigerator, refrigerator-freezer inside then, foaming and setting.Not only cost is high, and difficulty of processing is big, in case the product 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.But inner bag, door courage for refrigerator, refrigerator-freezer generally do not stress, and do not need very high intensity.And ABS, HIPS lattice are higher, the one, increased the cost of refrigerator, refrigerator-freezer inner bag, door courage material, and the 2nd, 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, processing a kind of easily refrigerator ice cabinet inner bag door courage preparation methods.
Technical scheme of the present invention is that a kind of refrigerator ice cabinet inner bag door courage preparation methods is characterized in that: choose PS 100-110 weight part; Vilaterm 15-25 weight part, Vestolen PP 7052 10-20 weight part, Ben Yi Xi – Ding Er Xi – styrene block copolymer 10-20 weight part; Stablizer 0.3-0.6 weight part, oxidation inhibitor 0.5-0.9 weight part, lubricant 0.05-0.08 weight part; Pigment 0.04-0.06 weight part, weighting agent 1.5 – 2.5Weight part; Each material of above-mentioned weight part is put into impeller; Stirred 150 seconds-250 seconds, whipping temp is a room temperature, and the material after will stirring is again extruded by two bar cocurrent and parallel plastics extruders; Body temperature: 190-225 ℃; Head temperature: 195-215 ℃, the material after extruding is being cooled off by water temperature 40-60 ℃ water, accomplishes preparation.Described stablizer is Zinic stearas or calcium stearate; Described oxidation inhibitor is antioxidant 264 or antioxidant 1076; Described lubricant is fatty acid ester or butyl stearate; Described pigment is ultramarine, titanium white Tio2, manganese violet, carbon black; Described weighting agent is light calcium carbonate, treated carbonates.
Production cost of the present invention is lower; Complete processing is simple; The present invention is applied to inner bag, the door courage of refrigerator, refrigerator-freezer, has replaced original refrigerator, refrigerator-freezer and has adopted simple ABS, HIPS to make refrigerator, refrigerator-freezer inner bag, door courage etc. to bring complicated complete processing, makes product inside can have attractive in appearance, fashion, generous characteristics; Accepted by client easily, can satisfy the requirements at the higher level of client product impression effect.
