The present invention relates to the field of lubricant, and specifically provides a lubricant composition and its preparation method and use. The lubricant composition comprises a base oil and rubber particles having radiation crosslinked structure dispersed therein, wherein the base oil is continuous phase and the rubber particles are dispersed phase. The viscosity of the lubricant composition of the present invention can be effectively adjusted as temperature changes. As compared with the lubricant composition comprising chemically crosslinked rubber particles, it has a lower viscosity at low temperatures and a higher viscosity at high temperatures, and has a relatively high viscosity index, which can meet the application requirements at the temperature above 200&#xb0; C. In addition, the lubricant composition of the present invention also has excellent antiwear and friction-reducing properties.

Lubricant composition, and preparation method and use thereof

The present invention relates to a resin composition having an improved haze effect and light transmittance and a process for preparing the same. The resin composition comprises blended components: a) a matrix resin; and b) crosslinked copolymer microspheres; wherein the crosslinked copolymer microspheres are alternating copolymers formed from monomers having anhydride, amide and/or imide groups, with olefin monomers and/or furan and its derivatives and optionally crosslinked with a crosslinking agent; preferably, the resin composition has a haze of not less than 92%, and a light transmittance of not less than 55%, preferably a haze of not less than 92%, and a light transmittance of not less than 59%, and more preferably a haze of not less than 95%, and a light transmittance of not less than 59%. The resin composition is energy efficient in use, provides excellent light diffusing effect, and, at the same time reduces the material cost.
