The invention discloses a kind of preparation methods of dozer liner plate, the following steps are included: S1: Corvic and high-density polyethylene resin are kneaded, add metal inhibitor, paraffin oil, sericite in powder, molybdenum disulfide and aggregate, after mixing, it squeezes out, be cooled and shaped to obtain sheet liner plate substrate；S2: by terpene resin and polyflon heating fusing, and being added carbon fiber, EP agent, levelling agent, antioxidant, ultraviolet absorbing agent and xanthan gum, is squeezed out after mixing up to corrosion-resisting film with being added to curtain coating in extruder；S3: liner plate substrate is pressed with corrosion-resisting film, then is carried out hot mastication, cooled and solidified up to dozer liner plate finished product.Preparation method proposed by the present invention, easy to operate, favorable reproducibility can carry out industrialized production, and liner plate substrate and corrosion-resisting film are firmly combined, and good to the protecting effect of dozer, the corrosion resistance and wear-resisting property of the dozer liner plate of preparation are excellent, long service life. |
