Technical field
The present invention relates to polyurethane elastomer preparation method fields, and in particular to a kind of high-performance thermoplastic polyurethane elasticity
The preparation method of body.
Background technique
Polyurethane elastomer (TPU) is a kind of material between ordinary rubber and plastics, its biggest characteristic is that hard
It spends and keeps higher elastic (elongation is up to 400% to 1000%), wearability in range (shore A10 degree to shore D75 degree)
Brilliant (about 2-10 times of natural rubber), has good mechanical strength, oil resistivity and ozone resistance, cryogenic property also to go out very much
Color.Therefore it is just rapidly developed once coming out, application surface is just very extensive.China is the most potential and desired city of polyurethane
, there has also been very big development for polyurethane elastomer.
With implementing for economic policy, it is contemplated that each department of national economy is increasingly urgent to the needs of polyurethane material, poly- ammonia
The development of ester elastomer various product is very rapid, forms the dual-use new frame based on civilian.Product kind, production
Ability and yield are all doubled and redoubled, and technical level significantly improves, and application obscure portions are also expanded to metallurgy, stone by national defence, space flight department
Numerous industrial departments such as oil, mining, automobile, water conservancy, weaving, printing, medical treatment, sport, grain processing, building materials.Elastic polyurethane
The steady growth stage is stepped into the development of body class.
High-performance polyurethane elastomer not only has the performance characteristics of general polyurethane, also has such as resistant to hydrolysis
Property, cold flexibility, microbial resistance and mould characteristic, high resilience, electrical insulating property, excellent cryomechanics mechanical performance,
The higher performance characteristic such as ambient temperature curing processability, and these higher performance characteristics, so that high performance elastomer exists
There are good application prospect in the more areas of national economy, especially special dimension.But existing thermoplastic elastomer (TPE) is drawn
It stretches intensity and flexibility performance is relatively poor, be not able to satisfy ever-increasing market demand gradually.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of high-performance thermoplastic polyurethane elastomer, existing to solve
The problem for having the thermoplastic polyurethane elastomer performance in technology poor.
The present invention provides a kind of preparation methods of high-performance thermoplastic polyurethane elastomer, by mass percentage, including
Following component:
Polyester polyol, isocyanates and chain extender are preheated respectively, temperature respectively reach 80~100 DEG C, 40~
60 DEG C, 60~90 DEG C, then by the three kinds of raw materials and catalyst, SBS, antioxidant, lubricant, ultraviolet absorber and resistance to after preheating
Double screw extruder is added in hydrolytic reagent, and extrusion reaction is carried out under 90~180 DEG C, the revolving speed of 200~250rpm, through underwater after
Pelleter is granulated, 6~10h of vacuum post curing in drying machine, and removal moisture drying to moisture is less than 300ppm, system in drying tower
It is standby to obtain high-performance thermoplastic polyurethane elastomer.
Further, the number-average molecular weight of the polyester polyol is 1000~6000.
Further, the isocyanates is selected from 4,4- methyl diphenylene diisocyanate, toluene di-isocyanate(TDI), different Buddhist
One of your ketone diisocyanate, hexamethylene diisocyanate or any two kinds of mixture.
Further, the chain extender is the straight diol of C4~C8, the symmetrical two terminal hydroxy groups object containing phenyl ring, contains phenyl ring
One or more of asymmetrical two terminal hydroxy groups object mixture.
Further, the antioxidant be selected from antioxidant 1010, antioxidant 1076, antioxidant 1024, antioxidant 1098,
The mixture of one or more of antioxidant 245.
Further, the lubricant is amide series lubricant agent.
Further, the ultraviolet absorber selects 2- (- 5 ˊ of 2 ˊ-hydroxyl-aminomethyl phenyl) benzotriazole, 2- hydroxyl
Base -4- methoxy benzophenone or amine hindered phenol.
Further, the hydrolysis agent selects Carbodiimides.
Further, the catalyst is being selected from stannous octoate, dibutyl tin dilaurate, lead octoate, two acetic acid two just
The mixture of one or more of butyl tin.
Beneficial effect using aforementioned present invention technical solution is:
The high-performance thermoplastic polyurethane elastomer that the present invention is synthetically prepared using " one-step method ", it is easy to process, have compared with
High flexibility, can be used as the material with direct body contact, such as elastic band, shoulder belt, concrete principle are as follows:
(1) SBS (Styrene-Butadiene-Styrene Block Copolymer) has excellent tensile strength, skin-friction coefficient
Greatly, low temperature performance well, excellent electrical properties, processing performance is good, can be effective through addition SBS into thermoplastic polyurethane elastomer
Improve the tensile strength and flexibility of final product；
(2) thermoplastic poly ammonia is further promoted by addition hydrolysis stabilizer, anti-enzyme agent, ultraviolet absorbing agent and antioxidant
The comprehensive performance of ester elastomer；
The high-performance thermoplastic polyurethane elastomer obtained by the method for the invention can reach following technical indicator: hardness is
80-90A；Tensile strength is 35-40MPa；Elongation percentage is 550%-650%；Abrasion are 27-30mm3, molecular weight distribution width
(DMW)<2；Number-average molecular weight (Mn) is 50000-80000.
