Description
Technical field
The present invention relates to a kind of preparation method of new material, is to be related to a kind of system of high-strength polyurethane more specifically
Make method.
Background technology
Polyurethane material made from conventional method, although possessing good toughness, intensity and wear-resisting in some applications
Power is inadequate, is insufficient for the needs of high intensity, high-wearing feature, so being necessary to transform classical production process, improves
Its intensity and wearability have very big significance.Applicability for lifting polyurethane, meet the needs of various high requests, create
Considerable prospect for sales is equally significant, will create good benefit for society and enterprise.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of preparation method of high-strength polyurethane, with
Meet the material property needs of high intensity, high-wearing feature.
The present invention solve prior art technical scheme be：The preparation method of high-strength polyurethane, comprises the following steps：
A, filler is prepared by the 10%-20% of the percentage by weight of common polyurethane material, and at a temperature of 100 DEG C -120 DEG C
Drying is made standby for 4 hours；Filler can be inorganic filler or organic filler, or the mixture of inorganic filler and organic filler；
Wherein described inorganic filler is acetylene carbon black, titanium dioxide, calcium carbonate, talcum powder, 4A molecular sieves, aluminum sulfate, magnesia, organic
Bentonite or fume colloidal silica；Described organic filler is phenolic resin, acrylic ester oligomer, Styrene oligomer, ring
Oxygen tree fat, PVC paste resin；
B, conventional polyurethanes material pours into reactor, and the temperature for being preheating to 80 DEG C -100 DEG C is standby；
C, the agitator of reactor is started, control mixing speed is in 70 r/min -80r/min, and control temperature is at 80 DEG C -100 DEG C
Between, the ready fillers of step a are then slowly added into, filler must be slowly added into the conventional polyurethanes material in reactor
In, control speed ensures that polyurethane surface does not have the buildup of filler, until the ready fillers of step a are all added simultaneously at once
Into step d；
D, 100r/min -120 r/min are arrived into the mixing speed lifting of reactor；Temperature is controlled to be stirred between 80 DEG C -100 DEG C
It is that high-strength polyurethane finished product is formed after -2 hours 1 hour to mix the time.
The high-strength polyurethane that the inventive method is produced, its intensity increase than conventional polyurethanes increase about 30%, abrasion resistance
Add about 40%, meet the material property needs of high intensity, high-wearing feature.With preferable market prospects, can be createed for enterprise
More economic benefits and social benefit.
