Problems solved by technology

Plastic has strong corrosion resistance, does not react with acid and alkali; low manufacturing cost, durable, waterproof, light weight and other advantages, but due to the non-natural degradability of plastic, it will produce toxic gas when burned, and recycling is very difficult. And economically uneconomical, it has now become the number one enemy of mankind

Embodiment Construction

[0006] The present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0007] see attached image

[0008] The specific steps are: 1) Pre-treat the recycled waste polystyrene foam, add the polystyrene to be cleaned together with hot alkaline water into the reactor, heat and stir thoroughly, and then take out the polystyrene and put it into the clear water pool Stir and clean to achieve the purpose of decontamination; 2) Pulverize with a pulverizer, or manually if the amount is small; 3) Measure a certain proportion of isoamyl acetate, chloroform, and acetone to prepare a mixed solvent. Add a certain amount of pretreated waste polystyrene foam into the prepared mixed solvent at room temperature, and stir to fully dissolve it; 3) After it is completely dissolved, add an appropriate amount of emulsifier dodecylbenzene Sodium sulfonate, modifier, plasticizer dibutyl phthalate 1-3; antifreeze ethylene glycol,...

Abstract

The present invention relates to new applications of a waste polystyrene foam plastic, wherein a waste polystyrene foam plastic is completely dissolved with a low-toxicity, inexpensive and industrial-grade solvent so as to be adopted as a base material, and then an emulsifier, an anti-freezing agent, a solid filler, a modifier, a pigment and the like are added to prepare a coating material. According to the present invention, the problem of plastic treatment is effectively solved, and the prepared coating material has advantages of low price, good adhesion, acid resistance, alkali resistance, fading resistance and no environment pollution, and can be widely used as the exterior wall coating material.

Description

technical field [0001] The invention relates to a new application of waste polystyrene foam plastics, which uses low-toxic and cheap industrial-grade solvents to fully dissolve waste polystyrene foam plastics at room temperature as a base material, and then adds emulsifiers, antifreeze agents, Prepare coatings from solid fillers, modifiers and pigments. This project belongs to the field of industrial chemicals. Background technique [0002] Plastic is one of the three major synthetic materials, with a wide variety, mainly including ethylene, polypropylene, polypropylene, and resin. Different varieties have different waste degradation products. There are many ways to deal with waste plastics, such as stacking and landfilling, incineration, and photobiologically decomposed plastics. Plastic has strong corrosion resistance, does not react with acid and alkali; low manufacturing cost, durable, waterproof, light weight and other advantages, but due to the non-natural degradabili...
