Problems solved by technology

Among them, the building materials industry accounts for the largest proportion, which is 60%, followed by the packaging industry, and several other industries with small-scale applications. The processing performance and physical and mechanical properties of hard PVC produced at this stage are not very significant, and its thermal strength is obviously insufficient. rate is small

Embodiment 1

[0016] Embodiment 1, an ACR and PVC blending process, a kind of ACR and PVC blending process, is characterized in that: it includes PVC resin, ACR auxiliary agent, stabilizer, lubricant, processing aid, titanium dioxide.

[0017] Quality ratio:

[0018] PVC resin 86-92.5% ACR additive 10-20%

[0019] Stabilizer 0.2-1.7% Lubricant 0.5-1.5%

[0020] Processing aid 0.5-1.2% Titanium dioxide 1.5-2.5%

[0021] A kind of flow process that is used to produce ACR and PVC blending process, this method comprises the steps:

[0022] (1) Add PVC resin, ACR auxiliary agent, stabilizer, lubricant and titanium dioxide in the above ratio in sequence in the container to prepare PVC base material.

[0023] (2) Then the base material and a certain amount of processing aids are cold-mixed to obtain a PVC dry mix, and then enter the kneading equipment for kneading.

[0024] (3) Put the base material in the kneading equipment into the cooling equipment.

[0025] Among them, the temperature req...

Abstract

The invention relates to an ACR (acrylic resin) and PVC (polyvinyl chloride) blending process. In the process, the following materials are used in percentage by mass: 86-92.5% of PVC, 1.5-2.5% of dibasic lead phosphate, 0.2-1.7% of lead stearate, 0.5-1.5% of calcium stearate, 0.5-1.2% of stearic acid, 1.5-2.5% of oxidized polyethlene wax, 0.2-1.5% of titanium white, 0.5-1.5% of CaCO3, 0.1-1.0% of processing aid and 0.2-1.5% of impact modifier. The ACR and PVC blending process has the beneficial effects that the processing performance of hard PVC can be improved, the physical and mechanical properties of hard PVC cannot be weakened, the hot strength is improved apparently and the coefficient of elongation is increased.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a blending process of ACR and PVC. Background technique [0002] PVC can be divided into hard PVC and soft PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains a softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited. Rigid PVC does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. Soft PVC is mostly used to make vacuum blister film for the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in ...
