Waste plastic regenerated environment-friendly particles and production process thereof

Abstract

The invention discloses waste plastic regenerated environment-friendly particles and a production process thereof. According to the process, poly-3, 5- diamino-1H-pyrazole-4-carboxylic acid allyl ester and 2, 3, 5, 6-tetrafluoroterephthalic acid amide are added, and the fluorobenzene structures are introduced, the weather resistance and the corrosion resistance of the material are higher; with introduction of pyrazole structures, the ultraviolet aging resistance and the flame retardance of the material are further improved; the tensile strength of the prepared waste plastic regenerated environment-friendly particles is 54.7-55.2 MPa according to GB / T1040-2006 measurement, the limit oxygen index is 38.239% according to GB5454-85 measurement, and the technical problems in the prior art thatwaste plastic is not high in strength and prone to combustion are solved.

Description

technical field [0001] The invention relates to the technical field of plastic granule production, in particular to a waste plastic regenerated environmental protection granule and a production process thereof. Background technique [0002] At present, the rapid development of the plastics industry has brought many conveniences to people's lives, but at the same time it has also brought a series of social problems caused by waste plastics and waste plastics. The application of plastic products has penetrated into every corner of society, from industrial production to basic necessities of life, plastic products are everywhere. People have begun to find that plastic waste has quietly come to us, seriously affecting our health and living environment. For example, some agricultural lands have begun to reduce production due to the impact of abandoned mulch, and the "white pollution" caused by waste plastics has begun to cause headaches. , Lunch boxes that do not rot or decompose...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of recycled environmental protection particles of waste plastics and its production process, to solve the following technical problems: (1) by adding poly-3,5-diamino-1H-pyrazole-4-carboxylate allyl 2, 3,5,6-Tetrafluoroterephthalic acid amide, the introduction of fluorobenzene structure, makes the weather resistance and corrosion resistance of the material stronger, and the introduction of pyrazole structure, further improves the UV aging resistance and flame retardancy of the material, and is prepared According to GB / T1040-2006, the tensile strength of waste plastic recycled environmental protection particles is 54.7-55.2 MPa, and the limiting oxygen index is 38.239% according to GB5454-85, which solves the problem that the strength of waste plastics in the prior art is not high and is easy to burn (2) Through the setting of the air expansion shaft, the installation of plastic pipes with different inner diameters is convenient, and through the setting of the conveyor belt, it is convenient for the plastic pipes to enter and exit the polishing chamber before polishing and after polishing, and the rotation of the air expansion shaft can drive The plastic tube rotates by itself, which facilitates the comprehensive polishing of the plastic tube by the polishing roller, and solves the technical problem that the polishing equipment in the prior art cannot automatically fully polish the surface of the plastic tube; (3) the polished plastic tube is transported from the opening through the conveyor belt After being transported out, the regenerated environmental protection particles can be obtained after being cut by a granulator. The polishing process of the plastic pipe is carried out in the water in the sink, which effectively prevents the plastic chips on the surface of the plastic pipe from splashing during the polishing process, and at the same time ensures that the temperature of the polishing roller during the polishing process will not Too high, so as to avoid the temperature of the polishing roller from softening the plastic pipe, and solve the problem in the prior art that the plastic chips generated during the polishing process of the plastic pipe are easy to splash, and at the same time, the plastic pipe is easy to soften due to the high temperature during polishing
