Abstract
The recovering and treating method of waste glass fiber reinforced plastic is to treating waste glass fiber reinforced plastic into grains and to utilize the grains as the stuffing for sheet molding compound (SMC). The said method solves the problem of compatibility and adhesion of the waste with resin, reinforcing material and other components and makes SMC possess excellent mechanical performance.
Description
Background technology
The invention belongs to technical field of composite materials, be specifically related to a kind of recovery and treatment method of glass reinforced plastic waste.
Background technology
In decades, glass reinforced plastic has been widely used in all trades and professions with the characteristic of its high-strength light, many excellences such as corrosion-resistant.But along with glass reinforced plastic is used the increase of time and the continuous growth of output in China, the amount of scrap stock that produce in the production process and old glass fiber reinforced plastics product the like waste increases gradually, add the corrosion-resistant of glass reinforced plastic, be difficult for the nature weathering, at present its waste is handled as building waste or consumer waste filling and embedding mostly, and the pollution problem of environment is become increasingly conspicuous.For the recovery of glass reinforced plastic waste with utilize problem to put on agenda day by day.
Present domestic glass reinforced plastic waste is handled as building waste or consumer waste filling and embedding mostly, abroad the method that also has burning adopted or cracking to handle.Also there is the glass reinforced plastic of employing waste to pulverize material in the document and makes permanent water drain well lid (Wang Jinxi, Chinese patent application number 01115069), also there is the glass reinforced plastic of employing waste to pulverize material and makes glass filament reinforced plastics burning into sand pipe RPM (Gao Yongfei etc., glass reinforced plastic/matrix material, 2001,1:19).
Can reclaim and utilize by suitable method glass reinforced plastic waste, the glass reinforced plastic waste might reclaim and utilizes by following approach: (1) is with the burning that acts as a fuel of glass reinforced plastic waste; (2) Pintsch process extracts useful chemical ingredients; (3) mechanical disintegration, particle reclaims.Because present most of glass fiber reinforced plastics products require to have fire retardancy, and most glass fiber reinforced plastics product all contains a large amount of mineral fillers and strongthener, and the burning that acts as a fuel is unsatisfactory.Same content owing to resin in most of glass fiber reinforced plastics products is limited, adds the facility investment costliness, complex process, and the chemical that Pintsch process can extract is very limited, also is not best selection at least at present.
Summary of the invention
The objective of the invention is to propose a kind of technology simple, handle the recovery and treatment method of glass reinforced plastic waste easily, and realize innoxious, recycling.A kind of product of recycling glass waste is proposed simultaneously.
The glass reinforced plastic waste recovery and treatment method that the present invention proposes is that the glass reinforced plastic waste is ground into powder, then as the stopping composition of slice plastic (SMC); The diameter of glass reinforced plastic waste pulverized particles is not more than 2mm, and staple length is not more than 6mm, in the sheet molding compound, is 100 weight parts in unsaturated polyester resin, and the consumption of glass reinforced plastic waste is 60-120 part.
Usually generally to add the talcum powder of a great deal of or lime carbonate in the sheet molding compound (SMC) as stopping composition.And all contain a large amount of mineral fillers and strongthener in the glass fiber reinforced plastics product, and after pulverizing, its waste contains the inorganic components of a large amount of similar talcum powder or lime carbonate, and therefore, the present invention adopts mechanical means that the glass reinforced plastic waste is pulverized the stopping composition of back as SMC.Realized the recycling of waste.
With the sheet molding compound of glass reinforced plastic waste as stopping composition, (SMC) its moiety is as follows:
100 parts of unsaturated polyester resins (weight)

Coupling agent 0-1 part (weight)
Remover 1-5 part (weight)
Strongthener 20-50 part (weight)
In the above-mentioned materials, described unsaturated polyester resin is to contain the cinnamic commercially produced product that can be used for making SMC.
Described initiator is azo-initiator or peroxide initiator, has suitable thermal initiation temperature and thermal initiation time.
Described stopping composition is the mixture that the pulverizing material of glass reinforced plastic waste or this type of are pulverized material and talcum powder, lime carbonate.The pulverizing material particle diameter of glass reinforced plastic waste is not more than 2mm, and staple length is not more than 6mm.
Described thickening material is the inorganic powder of similar magnesium oxide one class, and thickening material has certain surfactivity.
Described low shrinkage additive is thermoplasticity class plastics, has the suitable polymerization degree, and has appropriate solvability in vinylbenzene.
Described coupling agent is a silane coupling agent, can promote the adhesive property of resin and glass fibre.
Described remover is the stearic acid material, is used to help the demoulding of SMC goods.
Described strongthener is an alkali free glass fibre, and the length of glass fibre is 3-6cm.
Compared with prior art, the present invention adopts mechanical means that the glass reinforced plastic waste is ground into diameter and is not more than 2mm, staple length is not more than the particle of 6mm, control well and pulverize the particle size of expecting, with its part or all of talcum powder that replaces in the SMC moulding compound, solve the glass reinforced plastic waste simultaneously and pulverized material and resin, strongthener and other compatibility between components and adhesive property problem, obtained good mechanical property and economy.
