Description

Utilize veneer thermosetting foam plastics regenerated plates and the method that is equipped with made of paper

Technical field

The present invention relates to a kind of veneer thermosetting foam plastics regenerated plates and method that is equipped with made of paper of utilizing, belong to resource and reclaim and utilize again the field.

Background technology

At present, for the recovery and the utilization of waste thermosetting foam plastics, we have applied for following patent: (1) Chinese patent " a kind of plastic material that utilizes the waste thermosetting foam plastics preparation and preparation method thereof ", CN 101629025B; (2) Chinese patent " a kind of method of utilizing waste thermosetting foam plastics to prepare composite board ", application number is 200910305368.8.That has introduced waste thermosetting foam plastics in the patent utilizes method again, mainly be the toughness of improving thermosetting foam plastics by solid epoxy resin and rubber, be hot pressed into regenerated plates, but the use of epoxy resin need add epoxy curing agent, curing agent is an organic amine, and human body has been caused harm.

And we find that the main quality requirement of brown paper is pliable and tough solid, the bursting strength height, can bear big pulling force and pressure does not break, and some three ply boards of finishing usefulness have just utilized these characteristics of brown paper in the life, filler is done with wood powder in centre at sheet material, upper and lower surface brown paper is hot pressed into sheet material then.We imitate this method, and (U.S. line paper has good adherence, the tearing toughness height also to have found U.S. preferably line paper of toughness and art paper; The retractility of art paper is little, and intensity is higher, the tensile strength height, water-resistance is good), placing it in waste thermosetting foam plastics powder upper and lower surface and be hot pressed into sheet material, technology is simple, good looking appearance, cost is low, and has obtained toughening effect preferably.

Summary of the invention

The object of the present invention is to provide a kind of veneer that utilizes to prepare thermosetting foam plastics regenerated plates and method,, and can improve the toughness of regenerated plates for the cycling and reutilization waste thermosetting foam plastics provides an approach.

A kind of veneer thermosetting foam plastics regenerated plates that is equipped with made of paper that utilizes of the present invention, it is characterized in that posting veneer paper on the two sides of thermosetting polyphenylene ethylene-propylene nitrile foamed plastics, veneer paper is a kind of in 80g brown paper, 120g brown paper, U.S. line paper or the art paper.

Utilize the preparation method of the veneer thermosetting foam plastics regenerated plates that is equipped with made of paper, be in mixer, to add waste thermosetting polystyrene-acrylonitrile foamed plastics powder 80-90 mass parts, plasticizer phthalic acid dioctyl ester or chlorinated paraffin wax 5-10 mass parts, fire retardant 2-7 mass parts, pigment carbon black or iron black 0-3 mass parts successively, add a kind of auxiliary agent down after every kind of auxiliary agent of wherein every adding all will mix by the time more successively; Promptly get material powder after mixing; Material powder is carried out preheating under 120-160 ℃; Material powder after the preheating evenly is taped against in the mould, spreads veneer paper simultaneously, carries out hot-formingly, and wherein pressure is 10-15MPa, and temperature is: 147~187 ℃ of patrix temperature, and 140~180 ℃ of counterdie temperature, the time is 10-20min; Sheet material after the moulding is carried out low-temperature shaped, wherein pressure is 10MPa, and cooling gets final product naturally.

Described waste plastic foam powder is a 20-100 order powder.

Described fire retardant is that brominated epoxy resin, tricresyl phosphate phenol, butylbenzene are a kind of in phosphate or the resorcinol biphosphonate.

The material powder that the present invention uses mainly is waste thermosetting polystyrene-acrylonitrile foamed plastics, because the discarded intensity height of thermosetting foam plastics but fragility is big own, all kinds of leatheroid are sticked on the surface, can play storeroom physics humidification, thereby improve the toughness of system, and can improve intensity, corrosion resistance and the water proofing property etc. of material.The invention provides a kind of method of utilizing veneer to prepare the thermosetting foam plastics regenerated plates, by hot-forming, utilize all kinds of veneer paper that thermosetting foam plastics sheet material is carried out physical modification, need not add adhesive, solvent-free formaldehydeless, safety and environmental protection, and improved the impact property of sheet material, also have waterproof, property such as fire-retardant, corrosion-resistant, be with a wide range of applications.
