Embodiment 1

[0043] Prefabricated surface film forming tempered glass mold:

[0044] After cleaning the toughened glass with alkaline water and clean water for 3 times until there are no stains or traces, it is dried at 100°C for later use; the PVC strip is bonded by electric welding, and a square cavity is formed in the toughened glass; 4 parts by mass PS diffuser and 0.08 parts of dibenzoyl peroxide are dissolved in 100 parts of polymethyl methacrylate prepolymer, and then 7 parts of pigments (common coloring pigments and near-infrared reflective pigments) are added Black is mixed in a ratio of 1:1) to obtain a mixed slurry after grinding, and then add 0.1 part of N,N-dimethylaniline to the mixed slurry to obtain a pre-filming slurry; flow the pre-filming slurry to the belt In the tempered glass with square PVC adhesive strips, flow coat it twice and let it stand at room temperature for 3 hours to form a 400μm dry film; just close the template and upper clamps.

[0048] Prefabricated surface film forming tempered glass mold:

[0049] After cleaning the tempered glass with alkaline water and clean water 4 times until there are no stains or traces, it is dried at 100°C for later use; the PVC adhesive strip is bonded by electric welding, and a square cavity is formed in the tempered glass; 5 parts by mass PS diffuser and 0.05 parts of dibenzoyl peroxide are dissolved in 100 parts of polymethyl methacrylate prepolymer, and then 5 parts of pigments (ordinary coloring pigment and near-infrared reflective pigment Dynamix Green 30C612 are mixed in a ratio of 1:1). ) The mixed slurry is obtained by grinding, and then 0.05 parts of N,N-dimethylaniline is added to the mixed slurry to obtain the pre-filming slurry; the pre-filming slurry is flow-coated to the tempered steel with square PVC strips In the glass, flow coating once and let it stand at room temperature for 2 hours to form a 200μm dry film; just close the template and upper clamps.

Abstract

The invention discloses a recycling method of waste plastics, which comprises washing, drying, crushing, pulverizing and sieving waste plastics, dissolving them in acrylic ester monomers, adding appropriate amount of fillers, reinforcing and toughening agents, Mg (OH)2 flame retardant and adding a small amount of organic peroxygen initiator and N, N tertiary amine organic compounds, etc. are mixed and degassed, and cast into the tempered glass mold with pre-formed surface film, exhausted, buckled After standing at room temperature, it is solidified and shaped, and finally the plastic plate is obtained through high-temperature treatment, cooling, and release. The process of recycling waste plastics by this method is simple, the surface decoration effect of the developed plastic board is good, and it is not affected by the type and color of waste plastics, it can replace wood-plastic composite materials and improve the application grade; it can replace acrylic panels and reduce production costs; It can replace ordinary plastic boards and improve the decorative effect.

Description

Technical field [0001] The invention relates to the field of waste plastic recycling, in particular to a method for recycling waste plastic. Background technique [0002] At present, the recycling technology of waste plastics has attracted more and more attention. It includes hybrid waste plastics and single-variety waste plastic recycling technologies. Among them, the recycling and reuse technologies of mixed waste plastics include dissolving and preparing coatings and adhesives, pyrolysis and oil conversion, and incineration for power generation; the recycling and recycling technologies of single-variety waste plastics include mechanical blending, solvent dissolution, and thermal Melt processing method produces coatings, adhesives and boards. Especially for the production of plates, waste plastics need to be sorted, and the sorting work is very complicated; if mixed waste plastics are used to produce plates, there are problems with different colors and properties, especially ...
