Abstract
The invention discloses a preparation method of modified basalt fiber-whisker reinforced silane cross-linking wear-resistant master batches. The preparing the method comprises the following steps: uniformly mixing grafted master batches with basalt fiber after surface modification treatment, organic modified hydrotalcite and alpha-semi-hydrated gypsum whiskers after the surface modification treatment, and carrying out cross-linking reaction in a water bath, thus preparing the silane cross-linking wear-resistance master batches. According to the preparation method disclosed by the invention, hydrotalcite is used as filler, potassium dodecyl phosphate is adopted as an organic negative ion modifier, and magnesium-aluminum hydrotalcite is organic modified through an interlayer anion exchangemethod by utilizing the characteristic of replaceability of the interlayer anion of the hydrotalcite, so that the organic hydrotalcite is obtained; the adhesion between the hydrotalcite and a polyolefin matrix is enhanced; starch and nano calcium carbonate are used for filling the modified polyether resin, reinforcing and toughening functions are obtained, and the fluidity and the tensile propertyof the modified polyethylene can be enhanced.
Description
technical field [0001] The invention belongs to the field of plastic product materials for machinery, and in particular relates to a preparation method of a modified basalt fiber-whisker reinforced silane crosslinked wear-resistant master batch. Background technique [0002] LLDPE molecules mainly have a linear structure, and there are a certain number of short branched chains on the straight chain of the macromolecule, and the intermolecular stacking is very tight. Therefore, LLDPE has excellent flexibility and processing fluidity. However, its melting point is low, and its molecular chains are prone to slip. Under the condition of repeated friction, the friction heat generated can easily cause plastic deformation of the composite material, which seriously affects its performance and reduces its service life. [0003] As a representative of thermoplastics, polyethylene has always been concerned about its application value, and seeking a composite polyethylene that can save...
