Embodiment 1

[0026] Such as Figure 1-3 As shown, the embodiment of the present invention provides a PVC sheet high-transparency product processing aid ACR, including the following materials, and each weight part of raw materials is weighed according to the following formula: 70 parts of methacrylates, 10 parts of acrylates, emulsifier 2 parts, the emulsifier is allyl polyether, and the methacrylate, acrylate and emulsifier are put into a reaction tank for polymerization reaction to obtain the processing aid ACR.

[0027] By adding methacrylates, acrylates and emulsifiers into the reaction tank at one time, the reaction temperature is kept at 70-80 degrees Celsius, and the reaction pressure is controlled as normal pressure. The reaction tank includes a support base 1, the middle part of the upper surface of the support base 1 is fixedly connected with a ring-shaped support limit ring 4, and the two sides of the support limit ring 4 are fixedly connected with two symmetrical support limit c...

Embodiment 2

[0032] The raw materials were weighed according to the following formula: 73 parts of methacrylates, 11 parts of acrylates, and 3 parts of emulsifiers.

Embodiment 3

[0034] Weigh the raw materials in parts by weight according to the following formula: 76 parts of methacrylates, 11 parts of acrylates, and 4 parts of emulsifiers.

[0035] Embodiment three:

[0036] Weigh the raw materials in parts by weight according to the following formula: 81 parts of methacrylates, 23 parts of acrylates, and 2 parts of emulsifiers.

Abstract

The invention provides a processing aid ACR for PVC sheet high-transparency products, and relates to the technical field of production and manufacturing of processing aids ACR. The PVC sheet high-transparency product processing aid ACR is prepared from the following raw materials in parts by weight: 70-90 parts of methacrylate, 10-30 parts of acrylate and 2-5 parts of emulsifier, wherein the emulsifier is allyl polyether; the methacrylate, the acrylate and the emulsifier are put into a reaction tank for polymerization reaction, and processing aid ACR is obtained. According to the method, all materials participate in the polymerization reaction, no auxiliary substance is left in the product, the purity is high, subsequent refining treatment is not needed, the production process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of processing aid ACR, in particular to the processing aid ACR for high-transparency PVC sheet products. 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 of 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 aid ACR belongs to t...
