Abstract
The invention discloses a preparation method of a thermoplastic polyurethane elastomer, belonging to the field of preparation of high polymer materials. The preparation method comprises the following steps of: heating 35-45 percent of methylene diphenyl diisocyanate, 45-52 percent of polyester polyol and 8-15 percent of butylene glycol through storage tanks thereof respectively; making three components pass through respective metering pump respectively; stirring at a high speed in a mixing cavity at the temperature of 60-70 DEG C for mixing uniformly; feeding into a screw reactor for reacting and extruding; cutting into circular or elliptical particles by using a granulator; and drying and packaging, wherein reaction conditions are that: a reaction phase is 60-90 seconds, the output of a mixed solution is 310 kg/hr, a standard output ratio is 100/35.02, and the temperature of an output resin is 70 DEG C/60 DEG C. The preparation method has the beneficial effects of low energy consumption and environmental friendliness.
Description
Technical field
Method for preparing thermoplastic polyurethane elastomer belongs to macromolecule material preparation area.
Background technology
TPUE (being called for short TPU) is that one type of heating can the dissolved polyurethane products.It is the macromolecular compound with carbamate group that is got by macromole polyester polyol, small molecules divalent alcohol and vulcabond polymerization; In molecular structure by the soft section segmented copolymer of forming with hard section; The snappiness of its existing elastomeric material has the HS of engineering plastics again; (40 ~ 120) TPU has flexibility in very wide temperature; Have surrounding medium performances such as good oil-proofness, solvent resistance, anti-weather property and anti-energetic ray performance in addition; Wear resistance, tear strength, flexual strength, tensile strength, elongation, rebound resilience and shearing resistance and mechanical property such as shock-resistant are also very good.The characteristics of TPU are fusible solvable, can adopt multiple working method moulding, but shaped body, tubing, film, tackiness agent, coating and fiber are made in the product widespread use.So excellent physical and mechanical property, surrounding medium performance and processing characteristics make TPU obtain success in the application in fields such as industrial aspect, health care, sports goods, daily necessities and material.TPU can repeat processing and utilization simultaneously, and can be degraded into water and carbonic acid gas automatically at nature, has the characteristic that environment is not polluted, and in Future Social Development, will obtain application more and more widely.
Goal of the invention
The objective of the invention is provides a kind of less energy-consumption, free of contamination preparation method for society.
