example 1

[0030] According to the mass ratio of 1:10, the titanate coupling agent and the ethanol solution with a mass fraction of 90% were stirred and mixed, and then nano-titanium dioxide 3.5 times the mass of the titanate coupling agent was added, and then the temperature was 70°C, and the rotation speed was Under the condition of 500r / min, stir and react at a constant temperature for 5h. After the reaction is completed, centrifuge to collect the lower sediment, and wash the lower sediment with deionized water for 6 times, and then transfer the washed lower sediment to an oven. Drying at a temperature of 110°C to a constant weight yields titanate coupling agent-modified nano-titanium dioxide, which is the filler; in parts by weight, 50 parts of graphene oxide, 20 parts of octadecylamine, 120 parts of Parts of trichloromethane were mixed and poured into a three-necked flask. Under the condition of temperature of 95°C and rotation speed of 600r / min, the reaction was stirred at a constan...

[0034] In parts by weight, take 50 parts of graphene oxide, 20 parts of octadecylamine, and 120 parts of chloroform in turn, mix them and pour them into a three-necked flask. Stir the reaction for 24 hours, filter to obtain a filter cake, and wash the obtained filter cake with deionized water for 5 times, then transfer the washed filter cake to an oven, and dry it to a constant weight at a temperature of 110°C to obtain modified graphite oxide Pour PVC resin and solvent into a beaker with a mass ratio of 1:6, stir and mix with a glass rod for 20 minutes, let it stand for swelling for 24 hours, and then heat-treat at a temperature of 110°C until the solvent is completely evaporated, and then The material in the beaker is kept at a temperature of 60°C and left to age for 18 hours to obtain the aged material, and then the obtained aged material is frozen with liquid nitrogen for 4 hours, and then pulverized to obtain the pretreated PVC matrix resin; calculated in parts by weight ...

Abstract

The invention discloses a special high-glossiness modified master batch for a transparent PVC (Polyvinyl Chloride) hard product and belongs to the technical field of high molecular materials. The special high-glossiness modified master batch for the transparent PVC hard product, provided by the invention, is prepared from pre-treated PVC matrix resin, a stabilizing agent, a plasticizer, a lubricant, a de-foaming agent, a filler and modified graphene oxide, wherein the pre-treated PVC matrix resin is obtained by mixing and swelling PVC resin and a solvent, carrying out heat treatment and ageingand then freezing and crushing; the modified graphene oxide is prepared by heating graphene oxide, octadecylamine and trichloromethane and stirring and reacting; in a preparation process, the pre-treated PVC matrix resin, the stabilizing agent, the plasticizer, the lubricant, the de-foaming agent and the filler are mixed and then the modified graphene oxide is added; after the components are continually and uniformly mixed, extrusion and granulation, cooling and packaging are carried out to obtain the special high-glossiness modified master batch for the transparent PVC hard product. The special high-glossiness modified master batch for the transparent PVC hard product, disclosed by the invention, has excellent transparency, mechanical properties and light stability.

Description

technical field [0001] The invention discloses a high-gloss modified masterbatch for transparent PVC hard products, which belongs to the technical field of polymer materials. Background technique [0002] In the field of plastics industry, PVC has been widely used, but due to its low impact toughness, impact modifiers need to be added; in addition, the addition of inorganic nanoparticles can also play a role in toughening. Adding an impact modifier will increase the cost, and adding inorganic nanoparticles can reduce the cost, but it is not easy to disperse in the PVC matrix, so its content is limited. [0003] As an important part of polymer mechanochemistry, polymer solid-phase mechanochemistry is mainly concerned with the process of crushing (including crushing, grinding, crushing), mechanical processing (cutting, cutting, grinding, milling), fatigue wear, and abrasion of polymer materials. The study of chemical phenomena and chemical processes in such processes. Gu...
