Abstract
The invention provides toy filling material with light mass, liveliness and good elasticity. The invention adopts a proposal that syndiotactic polypropylene short fiber is used to replace hollow terylene short fiber. Because of the unique physical and chemical performance of SDP, the short fiber product has the advantages of sanitation, innocuity, health care, light mass, soft and smooth hand feeling and good elasticity, and the invention can be used as top grade joy filling material and can obtain the better effect.
Description
Technical field
The present invention relates to a kind of toy filler, belong to textile technology field.
Background technology
The present toy of selling or producing on the market as long as relate to filler, mostly all adopts the smooth PET Hollow short fiber of feel to make, and its hole count overwhelming majority adopts nine holes, and other hole count is also arranged.
The olefin polymerization catalysis of forming by metallocene and co-catalyst, compare with Ziegler catalyst commonly used, have higher activity, the catalyst that closes zirconium and methyl alumina (CH3AlO) composition as the dicyclopentadienyl dichloro is used for vinyl polymerization, high tens of times of specific activity Ziegler catalyst.Metallocene catalyst is used to produce polyethylene, polystyrene and copolymer etc.Have catalytic activity height, many, the single active sites of applicable monomer, polymer architecture and advantage such as can accurately control.Thereby can synthesize a series of polyolefin new products, as metallocene PE, metallocene polypropylene and metallocene polystyrene etc.Some polymer as the preparation of syndiotactic polypropylenes, syndiotactic polystyrene, cyclenes copolymer, optical activity oligomer, polymethylene cyclenes etc., can only adopt metallocene catalyst.Change the structure of metallocene ligand, can design the microstructure of tailor-made polymer thing.
Summary of the invention
The invention reside in provides a kind of other material that is different from existing toy filler.
What the present invention adopted is a kind of scheme that substitutes the PET Hollow short fiber with syndiotactic polypropylene (SDP) short fiber.
Concrete measure of the present invention is: SDP does not use the compound (the general catalyst that uses antimonous oxide to make polymerisation in the terylene industrial) that contains antimony in process of production, but come synthesis of syndiotactic polypropylene high polymer with metallocene catalyst, then the spinning technique route by general PP makes the SDP short fiber.
Because the physics and the chemical property of SDP uniqueness, its short fiber product also has the advantage of light weight, soft smooth, excellent elasticity except that having health, nontoxic, health care, make the charges of high-grade toy with it, can obtain better effect.
The specific embodiment
It below is specific embodiment of the present invention.
The syndiotactic polypropylene section that to adopt metallocene catalyst to produce, carry out the production of short fiber by following technological process: feed intake → drying → crystallization → screw rod melt extrudes → melt filtration → spinning → drawing-off → cut-out → test package → finished product.
The short fiber of above-mentioned production is further dried, loosely obtained more fluffy form, and situation with good conditionsi is preferably carried out ultra violet lamp and is disinfected.At last with its charges as the Olympic mascot FuWa of its Toy Factory's production.Client and client are all reflected well.
Claims (2)
1. the invention reside in the toy charges that the smooth good springiness of a kind of light weight is provided, what it adopted is a kind of scheme that substitutes the PET Hollow short fiber with syndiotactic polypropylene (SDP) short fiber, it is characterized in that: SDP does not use the compound that contains antimony in process of production, but come synthesis of syndiotactic polypropylene high polymer with metallocene catalyst, then the spinning technique route by general PP makes the SDP short fiber.
2. toy charges according to claim 1 is characterized in that the production procedure of SDP short fiber is: feed intake → drying → crystallization → screw rod melt extrudes → melt filtration → spinning → drawing-off → cut-out → test package → finished product.
