Abstract
Contain the synthetic perfume of 0.01～10 heavy % in the plastics of the present invention, can be fragrant for a long time.Synthetic perfume is sneaked in dry back of powder (grain) material in general-purpose plastics or the engineering plastics manufacturing plastics process and the operation before the product molding, and warp is the physical mixed aftershaping fully, obtains long-term odoriferous plastics.
Description
The present invention is applicable to plastics and manufacture method thereof.
At present, no matter the employed plastics of people are used for industry, still are used for daily life, do not have odoriferous characteristics, or can not be fragrant for a long time.
The objective of the invention is the plastics of high molecular polymer are carried out modification, make it have long-term odoriferous characteristic.This plastics are new and original, and emulation is strong, not only can satisfy the ever-increasing material and culture requirement of people better; Simultaneously, from medical angle, the cerebral nerve that fragrance can the mediator, hypermnesis, Ginseng Extract.
Characteristics of the present invention are to contain synthetic perfume in plastics, and the content of synthetic perfume in plastics is 0.01～10 heavy %, serves as better and weigh % with 0.1～5, are the best with 0.5～3 heavy %.In the plastics manufacturing processed, can select different proportionings according to desired fragrance concentration.
Manufacture method that can long-term odoriferous plastics of the present invention is under the situation of the manufacturing process that does not change conventional plastics, after synthetic resin moulding compound (grain) material drying process and before the plastic product forming operation, in synthetic resin moulding compound (grain) material, add synthetic perfume, and use any known method to stir, make it thorough mixing, then, carry out moulding with conventional method.Mixing and moulding should be carried out under＜220 ℃ temperature.Compounding process can carry out under normal pressure, but preferably sneaks under vacuum condition.Vacuum tightness is with 10
-3Be that processing condition best, the plastic product forming operation should strictly be controlled below the holder, must not surpass the decomposition temperature of plastics.
Figure is seen in technical process.
The present invention is applicable to various general-purpose plastics and engineering plastics, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, phenolic resins, polyamide, Merlon, polyformaldehyde, aminoplast and polysulfones etc.
Synthetic perfume used in the present invention can be selected different synthetic perfumes with the different process conditions of making plastic products by odor type as required, such as sandalwood type synthetic perfume, vanillyl odor type synthetic perfume etc.
Synthetic perfume can with other plastic additives (such as colouring agent etc.) simultaneously (or respectively) join during molding powder (grain) expects, and fully mix.
Because plastics of the present invention are before its moulding synthetic perfume to be added in synthetic resin moulding compound (grain) material, synthetic perfume with the plastics thorough mixing, be evenly dispersed in the plastics, so, the fragrance of spices comes out lentamente, and this odoriferous characteristics can keep considerable time.
Adopt the present invention can make new and original industrial goods, ornament and the daily necessities that various people like.
Example 1
On December 27th, 1985, the sandalwood type synthetic perfume of 1 heavy % is dosed in the plastics powder in the dried batch mixing process of polystyrene powder, and mixed.Then, adopt the injection moulding under the temperature about 160 ℃ of xS-ZY-125 plastic injection moulding machine, distributed the plastics of sandalwood type fragrance for a long time.Nearly so far 2 years of these plastics, still fragrance does not subtract.
Example 2
In July, 1987,1.5 heavy % vanillyl odor type synthetic perfumes are sneaked in the polyethylene powder before molding procedure, and stir.Then, at 200 ℃ of compacted unders, obtain distributing the plastics of vanillyl odor type with plastics extruder.
Claims (6)
