Description
Technical field
The present invention relates to materials science field, particularly potassium titanate crystal whisker cast composite nylon material and use the tapered crusher bowl profile shaft that this matrix material makes and hold.
Background technology
Monomer cast nylon has comprehensive mechanical intensity height as crystallinity molecule aggregation material, self-lubricating, and abrasion performance, advantage such as resistance to chemical attack and technology are simple, easy to operate, can make the big machinery structural part.From the sixties in last century, just in numerous areas such as metallurgy, chemical industry, mine, oil, be applied.Because the working temperature of monomer cast nylon goods has only about 100 ℃ and particularly impact property decline of low-temperature performance Celsius, limited the Application Areas of monomer cast nylon to a great extent.Hold with tapered crusher bowl profile shaft in the mine is exactly an example.It is that copper material is made, and every heavily about 300-600Kg does not wait, and is one of maximum spare part of mining equiment consumption copper.In order to solve the deficiency of monomer cast nylon on function, we make every effort to improve the physical strength of material on the basis that keeps original monomer cast nylon performance, wear resistant, and thermal characteristics, low temperature resistance to impact shocks etc. are to adapt to the requirement of workpiece to material property.
Summary of the invention
The purpose of this invention is to provide a kind of potassium titanate crystal whisker cast composite nylon material and use the tapered crusher bowl profile shaft that this matrix material makes and hold, this kind matrix material not only has the superperformance characteristics of casting sexual type nylon, and the heat-drawn wire of this matrix material is enhanced about more than once than monomer cast nylon; Shock strength is constant substantially in the time of-55 ℃ Celsius, good impelling strength in the time of can the temperature remains within the normal range, and frictional coefficient is lower than monomer cast nylon, and wear volume is littler more than five times than monomer cast nylon.
The preparation method of potassium titanate crystal whisker cast composite nylon material of the present invention may further comprise the steps:
(1) potassium titanate crystal whisker pre-treatment: the weighing potassium titanate crystal whisker is the amount of 5%-50% according to workpiece to the weight percent that the performance requriements of material takes by weighing potassium titanate crystal whisker and monomer hexanolactam; Load weighted whisker is put into the high mixer of heating, make the blade high speed rotating;
(2) take by weighing the dispersion agent peregal, take by weighing organo silane coupling agent KH550 by amount, dispersion agent peregal and organo silane coupling agent KH550 are mixed with 100 times of dehydrated alcohols with the amount of the weight ratio 5 ‰ of potassium titanate crystal whisker with the weight ratio 5 ‰ of potassium titanate crystal whisker;
(3) pour the ethanolic soln for preparing in high mixer mixing slowly;
(4) it is ℃ stand-by that mixed whisker is heated to 70 ℃ of constant temperature to 160;
(5) the monomer hexanolactam is weighed up, insert in the reactor heating and vacuumize;
(6) remove vacuum 80 ℃ Celsius the time, add catalyzer sodium hydroxide, the mol ratio of add-on and monomer hexanolactam is 0.005-0.015: 1, continue to be evacuated to-0.085Mpa;
When (7) treating that the hexanolactam solution reaches 130 ℃-170 ℃ Celsius, stop to vacuumize and put into pretreated potassium titanate crystal whisker mixing;
(8) add isocyanic acid lipid activator, the mol ratio of add-on and monomer hexanolactam is 0.002-0.004: 1, obtain the molten state matrix material;
(9) the molten state matrix material is poured in the mould of preheating, the insulation rear demoulding promptly obtains the potassium titanate crystal whisker cast composite nylon material.
Above-mentioned dispersion agent peregal is the product that OX-heart platform chemical plant, Benxi produces.
Potassium titanate crystal whisker cast composite nylon material of the present invention is compared with monomer cast nylon crystallinity molecule aggregation material, except that the mechanical property that keeps monomer cast nylon, self-lubricating, abrasion performance, premium properties such as corrosion-resistant, its heat-drawn wire is enhanced about more than once than monomer cast nylon, good impelling strength when shock strength still can the temperature remains within the normal range in the time of-55 ℃ Celsius, and this material has good properties of antifriction and wear resistance, good low temperature impact properties, sound absorption qualities, good thermal characteristics are the environment-friendly materials of a kind of ideal instead of copper and other non-ferrous metal.This material is applied in the mine and holds with tapered crusher bowl profile shaft, through overtesting, adapts to the requirement of workpiece fully, and performance is better than the tapered crusher bowl of copper profile shaft fully and holds.
The performance comparison of potassium titanate crystal whisker cast composite nylon material of the present invention and common monomer cast nylon such as following table:
The low temperature impact strength of matrix material of the present invention is constant as can be seen for data from last table, still can the temperature remains within the normal range good impelling strength down.Frictional coefficient is low, and abrasion loss is little, and heat-drawn wire improves nearly one times than monomer cast nylon, is the high-abrasive material under a kind of ideal high-load.
