As shown in Table 1, the shore hardness of product prepared by 1-8 of the embodiment of the present invention is 66-69 degree, and tensile strength is 20-
27MPa, elongation rate of tensile failure is 545-570%, and wearability wearing valve is 0.06-0.1cm3/ 1.61Km, and pass through 150 DEG C × 500h
Afterwards, elongation rate of tensile failure and tensile strength change are less, illustrates that the product prepared of the invention is wear-resisting, ageing-resistant performance is excellent.
And comparative example 1 removes raw material magnesia, comparative example 2 removes microcrystalline cellulose, wearability compared with Example 8, phase
Difference is larger, and other performances also decrease, and illustrate that nano micro crystal cellulose can improve the compactness of carbon network, so as to improve
Base material mechanical performance.And magnesia can greatly increase the heat-resisting and ageing-resistant performance of product.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff is made to technical scheme, without departing from technical solution of the present invention
Spirit and scope, all should cover among scope of the presently claimed invention.
