Abstract

The invention discloses a modified compound plastic, which is made from components: polypropylene, thermoplastic styrene-butadiene rubbers, attapulgite, silicon powder, phenolic resins, bentonite, sodium acrylate, aluminium nitride, dispersants, plasticizers and heat stabilizers. The modified compound plastic is steady in quality and excellent in mechanical and physical chemical properties, and has excellent adaptive efficiency. The modified compound plastic can improve structure performance and enhances weather resistance by adding the treated attapulgite. The modified compound plastic enables plastic components to be more uniform by mixing and pretreating the phenolic resins and the aluminium nitride, and enables organization structures to be more firm. The modified compound plastic can enhance plastic texture by adding the treated silicon powder, and is not easy to soften. The polypropylene and the sodium acrylate are mixed to add into a twin-screw extruder firstly, can improve integration of the polypropylene and other components, improve structure quality, and prolong service life.

Description

Technical field

[0001] The invention relates to the field of plastic production, in particular to a modified composite plastic. Background technique

[0002] Polypropylene (PP) has good corrosion resistance, rigidity and transparency, and is currently widely used to make packaging containers. However, polypropylene has poor impact resistance, becomes brittle at low temperatures, and is easier to age. In addition, in order to reduce the input of raw materials and reduce production costs, many manufacturers try to make the packaging containers lighter and thinner. , Therefore, the existing polypropylene is the original

[0003] The packaging container made of material feels very soft and has insufficient strength. It is easy to deform and break when held in the hand, and it is difficult to contain liquid or semi-liquid packaging, especially when it contains liquid or semi-liquid materials with higher temperature. High liquid or semi-liquid materials are easy to overflow and cause h...

Embodiment Construction

[0014] A modified composite plastic, in parts by weight, made of the following ingredients: 80 parts of polypropylene, 20 parts of thermoplastic styrene-butadiene rubber, 10 parts of attapulgite, 11 parts of silicon powder, 20 parts of phenolic resin, 5 parts of bentonite, acrylic acid 5 parts of sodium, 6 parts of aluminum nitride, 1 part of dispersant, 0.5 part of plasticizer, 0.2 part of heat stabilizer.

[0015] Further, the attapulgite is modified: dissolve stearic acid in kerosene to a concentration of 5.5%, then add the dried attapulgite, and after grinding for 2 hours, treat it at 100°C for 30 minutes at a constant temperature , Cool to room temperature, filter and dry.

[0016] Further, the silicon powder is mixed with a 4.5% phosphoric acid solution, treated at a constant temperature of 80-95° C. for 1-1.5 hours, filtered, and dried.

[0017] Further, the dispersant is sodium hexametaphosphate, the plasticizer is citrate, and the heat stabilizer is dibasic lead phosphite. ...
