Problems solved by technology

However, PVC also has some defects or deficiencies in performance, among which brittleness is one of the biggest shortcomings of PVC plastics.
Rigid PVC plastics have poor toughness and low impact strength at room temperature, and even worse toughness at low temperatures. When the temperature is lowered, they rapidly harden and become brittle, and are easily brittle when impacted. Applications in Low Temperature Environments

Embodiment 1

[0023] Use 100 parts by weight of montmorillonite and 6 parts by weight of long-carbon chain alkyl quaternary ammonium salt to stir evenly at 30°C to obtain a mixture for later use; heat the obtained mixture to 50°C and perform solid phase stirring for 1min, then cool to room temperature to obtain Modified montmorillonite: the modified montmorillonite of 100 parts by weight and the MBS of 10 parts by weight are prepared by emulsion polymerization to form a core-shell structure composite modified particle with montmorillonite as the core and MBS as the shell, The specific operation steps are: put the above-mentioned modified montmorillonite in the reactor of the condensing device, add deionized water, stir evenly, then add emulsifier, MBS, heat to 80°C and stir to disperse evenly, add conventional Initiator, react at 80°C for 2 hours, keep stirring, and cool to room temperature after the reaction, to obtain composite modified particles with montmorillonite as the core and MBS as...

Embodiment 2

[0027] Use 100 parts by weight of montmorillonite and 8 parts by weight of long-carbon chain alkyl quaternary ammonium salt to stir evenly at 50°C to obtain a mixture for later use; heat the obtained mixture to 70°C and perform solid phase stirring for 4 minutes, and then cool to room temperature to obtain Modified montmorillonite: the modified montmorillonite of 100 parts by weight and the MBS of 15 parts by weight are prepared by emulsion polymerization to form a core-shell structure composite modified particle with montmorillonite as the core and MBS as the shell, The specific operation steps are: put the above-mentioned modified montmorillonite in the reactor of the condensing device, add deionized water, stir evenly, then add emulsifier, MBS, heat to 85°C and stir to disperse evenly, add conventional Initiator, react at 85°C for 3 hours, keep stirring, and cool to room temperature after the reaction, to obtain composite modified particles with montmorillonite as the core a...

Embodiment 3

[0031] Use 100 parts by weight of montmorillonite and 10 parts by weight of long-carbon chain alkyl quaternary ammonium salt to stir evenly at 100°C to obtain a mixture for later use; heat the obtained mixture to 100°C and perform solid phase stirring for 8 minutes, and then cool to room temperature to obtain Modified montmorillonite: the modified montmorillonite of 100 parts by weight and the MBS of 20 parts by weight are prepared by emulsion polymerization to form a core-shell structure composite modified particle with montmorillonite as the core and MBS as the shell, The specific operation steps are: put the above-mentioned modified montmorillonite in the reactor of the condensing device, add deionized water, stir evenly, then add emulsifier, MBS, heat to 90°C and stir to disperse evenly, add conventional Initiator, react at 90°C for 3 hours, keep stirring, and cool to room temperature after the reaction, to obtain composite modified particles with montmorillonite as the cor...

Abstract

The invention relates to a low-temperature toughened PVC drainage pipe material, a preparation method and application thereof. The PVC drainage pipe material is prepared according to the following preparation method: taking montmorillonite and methyl methacrylate-butadiene-styrene copolymer as raw materials to prepare a compound modified particle with a core-shell structure through an emulsion polymerization method; and then blending the compound modified particle with PVC through melt, so as to prepare a ternary nanometer compound material. By selecting a specific nanometer particle to organically combine with an elastomer, the core-shell structural compound modified particle taking montmorillonite as a core and MBS as a shell is formed, and then the compound modified particle and PVC resin are subjected to melt blending, so that the compound modified particles are well dispersed in PVC matrix and give play to toughening reinforcing modification effect on PVC.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a low-temperature toughened PVC drainage pipe material and a preparation method and application thereof. Background technique [0002] The raw material polyvinyl chloride (PVC) used in PVC-U drainage pipe is a general-purpose plastic variety with excellent comprehensive performance, low price and wide source of raw materials. Its output and consumption are second only to polyethylene, and it has been widely used in various fields. However, PVC also has some defects or deficiencies in performance, among which brittleness is one of the biggest shortcomings of PVC plastics. Rigid PVC plastics have poor toughness and low impact strength at room temperature, and even worse toughness at low temperatures. When the temperature is lowered, they rapidly harden and become brittle, and are easily brittle when impacted. applications in low temperature environments. Therefore, improvin...
