Embodiment 1

[0026] Such as Figure 1-3 As shown, the embodiment of the present invention provides a PVC sheet heat-resistant modifier ACR, including the following materials, according to the following formula to weigh each part by weight of raw materials: 35 parts of styrene, 47 parts of acrylonitrile, 40 parts of methacrylates , 20 parts of α-methylstyrene, 30 parts of glycidyl methacrylate, PVC sheets are obtained by copolymerizing styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate Material heat-resistant modifier ACR, styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate copolymerization reaction equipment is anti-leakage reaction equipment.

[0027] The copolymerization pressure of styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate is normal pressure, and the copolymerization temperature is 75 degrees Celsius. Glycidyl methacrylate is synthesized by a phase transfer method. The synthesis method is ...

Embodiment 2

[0031] Glycidyl methacrylate is synthesized by an esterification ring-closing method. First, methacrylic acid and epichlorohydrin are subjected to a ring-opening esterification reaction to generate methacrylate-2-hydroxyl-3-chloropropyl. Then dehydrochlorination ring-closing reaction of methacrylic acid-2-hydroxyl-3-chloropropyl in the presence of sodium hydroxide solid or aqueous solution, or reflux in acetone solution of potassium carbonate to obtain the product.

Embodiment 3

[0033] The raw materials were weighed according to the following formula: 37 parts of styrene, 49 parts of acrylonitrile, 42 parts of methacrylates, 25 parts of α-methylstyrene, and 33 parts of glycidyl methacrylate.

[0034] The copolymerization pressure of styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate is normal pressure, and the copolymerization temperature is 77 degrees Celsius.

Abstract

The invention provides a PVC sheet heat-resistant modifier ACR, which relates to the technical field of modifier production. The PVC sheet heat-resistant modifier ACR is prepared by weighing the following raw materials in parts by weight according to the following formula: 35 parts of styrene, 47 parts of acrylonitrile, 40 parts of methacrylate, 20 parts of alpha-methyl styrene and 30 parts of glycidyl methacrylate. The PVC sheet heat-resistant modifier ACR is obtained through copolymerization of styrene, acrylonitrile, methacrylate, alpha-methyl styrene and glycidyl methacrylate, and the styrene, acrylonitrile, methacrylate, alpha-methyl styrene and glycidyl methacrylate copolymerization reaction equipment is anti-leakage reaction equipment. The modifier ACR of the PVC sheet material has good heat resistance, the reaction equipment during the polymerization reaction is safe, and the leakage of inflammable harmful substances is not caused.

Description

technical field [0001] The invention relates to the technical field of modifier production, in particular to a PVC sheet heat-resistant modifier ACR. Background technique [0002] PVC board is a board made of PVC as a raw material with a honeycomb mesh structure in cross section, and it is a vacuum blister film. It is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and several other industries with small-scale applications. According to the degree of softness and hardness, it can be divided into soft PVC and hard PVC. According to the production process, it can be divided into PVC crust foam board and PVC free foam board. The PVC processing modifier ACR belongs to the core-shell copolymer, and its shell is methyl ...
