Problems solved by technology

Although the existing pipe and film production can meet the requirements to a certain extent, but in the production of pipes, it is often found that there are longitudinal scratches on the surface of the pipe, the surface of the pipe is not glossy, and the problems of mold accumulation, resulting in frequent cleaning of the machine , which reduces the production quality and production efficiency of the pipe; when producing the film, the surface of the film is often rough and cracked, which leads to the inability to improve the efficiency of film production

Abstract

The invention discloses a PPA (phenylpropanolamine) master batch which is prepared from the following raw materials in parts by weight: 85-90 parts of polyethylene, 8-10 parts of antioxidant, 3-5 parts of aid and 1-3 parts of compatilizer. The invention also discloses a preparation method of the PPA master batch. The preparation method comprises the following steps: 1) proportioning: carrying out proportioning according to the PPA master batch, and uniformly mixing; 2) extrusion: adding the proportioned mixture in the step 1) into a double screw extruder, compounding and extruding; and 3) granulation: cooling the extrusion product in the step 2), and granulating to obtain the PPA master batch. In the tube and film production process, the added PPA master batch improves the product surface quality, enhances the product gloss, lowers the extruder die pressure, and reduces the product longitudinal scratch and the film splitting. The PPA master batch lowers the material deposit at the die orifice, reduces the machine cleaning frequency, reduces the consumption and die pressure, and can effectively enhance the productive efficiency.

Description

technical field [0001] The invention belongs to the technical field of polymer compound compositions, and in particular relates to a PPA masterbatch and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry and the film industry, the demand for pipes and films is gradually increasing. Existing pipes and films are usually made of polypropylene and polyethylene as raw materials with color masterbatch added. Although the existing pipe and film production can meet the requirements to a certain extent, but in the production of pipes, it is often found that there are longitudinal scratches on the surface of the pipe, the surface of the pipe is not glossy, and the problems of mold accumulation, resulting in frequent cleaning of the machine , which reduces the production quality and production efficiency of the pipe; when producing the film, the surface of the film is often rough and cracked, which leads to the inability...
