Abstract
The invention belongs to the technical field of polyurethane, relates to a heat-resistant thermoplastic polyurethane and a production process thereof. The heat-resistant thermoplastic polyurethane is prepared from the following materials: PCL-1000, PCL-2000, MDI, HQEE, TMP, DK2; the production process comprises the following steps: fusing the PCL-1000 and the PCL-2000, and then pouring into a three-neck flask of which the volume is 1000ml; then adding the DK2, TMP and HQEE into the three-neck flask, stirring and heating up to 100 DEG C; vacuumizing to -0.098-0.1MPa; dehydrating for more than 2 hours at 110-120 DEG C, cooling to 50-70 DEG C; mixing with the fused MDI at a high speed, placing into a mould of which the temperature is 80-90 DEG C, and then placing into a vulcanizer and pressing for 2-3 hours at 130-140 DEG C and then demoulding; placing the demoulded semi-product into an oven at 120+/-5 DEG C for vulcanization for 20-24 hours to obtain a finished product. The invention has the advantages of good high-temperature resistance, can resist the temperature of 100 DEG C, and is suitable for manufacturing sealing elements of equipment such as engineering machinery, hydraulic cylinders and the like.
Description
Technical field
The invention belongs to the polyurethanes technology field, refer in particular to a kind of heat-resistant thermoplastic polyurethane and production technique thereof.
Background technology
Thermoplastic polyurethane is a kind of thermoplastically TPU elastomerics; Because its good springiness, good, the various physical strength of rerum natura are good; Be widely used in ejaculation, extrusion, roll and be dissolved into processing modes such as solution-type resin; Be the plastic material that the plastic cement processer often uses, it processes the scope that product has been contained industrial application and civilian requisite.
TPU receives people's welcome day by day because of its superior performance and environmental protection notion; At present; The place of every use PVC; TPU all can become the substitute of PVC, but the weak point of TPU is: the heatproof that is used to do the thermoplastic polyurethane that sealing member uses has only about 60 ℃, can not satisfy the demand in product performance and market.
Summary of the invention
The purpose of this invention is to provide a kind of resistance toheat and reach heat-resistant thermoplastic polyurethane and production technique thereof more than 100 ℃.
The objective of the invention is to realize like this:
Heat-resistant thermoplastic polyurethane is prepared from the material of following parts by weight:
Polycaprolactone-1000 (PCL-1000): 80-150 part;
Polycaprolactone-2000 (PCL-2000): 150-250 part;
Diphenylmethanediisocyanate (MDI): 150-250 part;
Two (beta-hydroxyethyl) ethers (HQEE) of quinhydrones: 70-110 part;
TriMethylolPropane(TMP) (TMP): 2-8 part;
The montmorillonite-based nano properties-correcting agent (DK2) of hydramine intercalation: 0.5-3 part.
Above-mentioned polycaprolactone-1000 is that 100 parts, polycaprolactone-2000 are that 200 parts, diphenylmethanediisocyanate are that 180 parts, two (beta-hydroxyethyl) ethers of quinhydrones are that 87 parts, TriMethylolPropane(TMP) are that 5 parts, the montmorillonite-based nano properties-correcting agent of hydramine intercalation are 1 part (parts by weight).
The production technique of heat-resistant thermoplastic polyurethane; Produce by following process step: with pouring in the 1000ml there-necked flask after the polycaprolactone-1000 of weighing, polycaprolactone-2000 fusion; Again two (beta-hydroxyethyl) ethers of montmorillonite-based nano properties-correcting agent, TriMethylolPropane(TMP) and the quinhydrones of the hydramine intercalation of weighing are added the there-necked flask stirring heating and be warming up to 100 ℃, be evacuated to-0.098～0.1MPa, after 110～120 ℃ of dehydrations are more than 2 hours; Be cooled to 50～70 ℃; With the fused diphenylmethanediisocyanate mixed at high speed of weighing, insert in 80～90 ℃ the mould, described mould is put into 130～140 ℃ vulcanizer together with admixture suppress the demoulding after 2～3 hours; Work in-process after the demoulding are put into 120 ± 5 ℃ of baking ovens vulcanized 20～24 hours, get product.
The present invention compares the outstanding advantage of prior art: resistance to elevated temperatures of the present invention is good, the highest can anti-100 ℃ of high temperature; The present invention is applicable to Seal of Equipment parts such as making engineering machinery, hydro-cylinder.
