Abstract

The invention discloses modified polyvinyl chloride paste resin and a preparation method thereof. The modified polyvinyl chloride paste resin is prepared by compounding polyvinyl chloride paste resin with polyborosiloxane according to a mass ratio of (1 to 99)-(30 to 70); the modified polyvinyl chloride paste resin also comprises plasticizers; the mass ratio of the polyvinyl chloride paste resin to the plasticizers is (1 to 1)-(1 to 1.8). According to the modified polyvinyl chloride paste resin, polyborosiloxane distributed in the modified polyvinyl chloride paste resin as dispersion phase can absorb and consume one part of energy through rapid change of viscosity when the modified polyvinyl chloride paste resin is sheared or impacted, so that the polyvinyl chloride paste resin matrix is enhanced; after the modified polyvinyl chloride paste resin is impacted, the nondestructive deformation can be restored. The preparation method of the modified polyvinyl chloride paste resin is simple and convenient to operate, is suitable for commercial production and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a polyvinyl chloride paste resin and a preparation method thereof, in particular to a modified polyvinyl chloride paste resin and a preparation method thereof. Background technique [0002] Impact-resistant materials based on polyborosiloxane have attracted much attention in recent years. The material is a mastic-like material with a typical shear thickening effect. Its physical-chemical properties are stable and its impact resistance is excellent. However, the state of the cement determines that the deformation caused by the impact cannot be recovered after the impact is removed, so it is difficult to combine with the corresponding protective equipment in practical applications. In order to solve this problem, the material can be combined with resin or elastomer to form a composite material system, and the resin or elastomer can be used to endow the composite material with non-destructive deformation ability, and at the same...
