Problems solved by technology

[0003] However, PVC resin has the following defects: (1) poor heat resistance
PVC begins to thermally decompose at 120-130°C, releasing HCl gas, and the product is easy to soften and deform under the action of external force, which is not as stable as silica gel; (2) The impact resistance is poor
It is extremely brittle when impacted, and is far inferior to silicone in terms of softness and feel
Especially when PVC is used as a packaging material for electronic products, due to better requirements for odorlessness and antistatic properties, there are relatively large restrictions on the use of plasticizers and other agents that can improve mechanical properties

Abstract

The invention relates to the technical field of nylon, in particular to an odorless antistatic PVC composite material and a preparation method thereof, and the odorless antistatic PVC composite material comprises the following raw materials by weight: PVC, an odorless plasticizer, a modifier, a heat stabilizer, a lubricant, an antistatic agent, a flame retardant, a mildew inhibitor and an antioxidant. A core-shell particle modifier with nano silicon dioxide as a core, polymethyl methacrylate as a middle layer and polystyrene as an outer layer shell is prepared by an emulsion polymerization method; the dispersion problem of the nano silicon dioxide is effectively solved; meanwhile, by utilizing the characteristic that all layers of the core-shell particles are different in performance, whenthe core-shell particles are impacted, all the layers are prone to deformation to different degrees to form cavities, and compared with MBS of a core-shell structure, the toughening efficiency is higher, the inorganic rigid particles serve as cores, and the rigidity performance of PVC is well improved.

Description

technical field [0001] The invention relates to the technical field of ABS, in particular to an odorless antistatic PVC composite material and a preparation method thereof. Background technique [0002] PVC used to be the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. As a widely used PVC resin in the industrial field, it has excellent physical and chemical properties, which are mainly reflected in the following aspects: (1) Strong corrosion resistance and stable chemical properties. Except for a few solvents at room temperature, PVC resin can withstand Hydrochloric acid of any concentration, sulfuric acid below 90%, nitric acid below 50-60% and caustic soda below 20%; (2) Excellent flame retardancy and electrical insulation, the oxygen in...
