Description
Technical field
The present invention relates to a kind of Castor for trunk or bag PP Pipe Compound and preparation method thereof.
Background technology
Castor is a requisite component in case and bag, due to the handling characteristics of case and bag, higher requirement is had for the hardness of castor, toughness and tear strength etc., existing castor is that material is made by conventional TPU70D, molding time is longer, and hardness and tear strength all cannot reach needed for requirement.
Summary of the invention
The object of the invention is to overcome defect of the prior art, provide a kind of Castor for trunk or bag PP Pipe Compound and preparation method thereof, cost is low, soon shaping, good toughness, and tear strength is high.
The present invention is achieved by the following technical programs.
A kind of Castor for trunk or bag PP Pipe Compound, its composition is as follows by weight percentage:
PEBA-2000 49~51%

MDI 37~39%。
Above-mentioned a kind of Castor for trunk or bag PP Pipe Compound, wherein, described PEBA-2000 to be relative molecular weight be 2000 poly-hexanodioic acid-ethylene glycol butanediol ester dibasic alcohol.
Above-mentioned a kind of Castor for trunk or bag PP Pipe Compound, wherein, described Isosorbide-5-Nitrae-BDO is BDO.
Above-mentioned a kind of Castor for trunk or bag PP Pipe Compound, wherein, described MDI is 4,4'-diphenylmethanediisocyanate.
A preparation method for Castor for trunk or bag PP Pipe Compound, its method steps is as follows:
A, by weight percentage ratio claimed range, weigh each composite material.
B, by Isosorbide-5-Nitrae-BDO and PEBA-2000 mixing and stirring, initial whipping temp is 80 DEG C, uniform lift Heating temperature, and heat-up rate is 3-5 DEG C/3min, until temperature no longer heats up after being increased to 95 DEG C, adds MDI Keep agitation 5-10min and obtains elementary material;
C, elementary material is added oven for drying; bake out temperature is 120 ~ 180 DEG C; drying 6-10h makes elementary material be solidified into bulk material; take out and put into 85-95 DEG C of curing chamber post curing 12-16 hour; after slaking, then diameter is become to be about the dead small of 1-2cm, finally by Single screw extrusion by crusher in crushing bulk material; tablets press is used to be processed into Castor for trunk or bag PP Pipe Compound.
Beneficial effect of the present invention is: according to the characteristic of starting material self, by 1,4-BDO, PEBA-2000 and MDI are divided into twice heating and mix, can by the best of respective performance, utilize the Castor for trunk or bag that PP Pipe Compound of the present invention is obtained, have soon shaping, good toughness, the features such as tear strength is high, and bond effect is good.
