Abstract
The invention relates to a recycling and reusing process for a phenolic resin composite waste material. The process is applicable to recycling and reusing of leftover materials of interior decorative parts of automobiles. The process comprises the following main steps: crushing the phenolic resin composite waste material, adding polypropylene, a coupling agent and an auxiliary agent and carrying out uniform mixing so as to prepare a mixture; heating the mixture and carrying out heat preservation until the mixture is in a molten state; placing glass fiber cloth in a mold and transferring the molten mixture into the mold; and successively carrying out molding, cooling and demolding so as to obtain a finished product. The invention has the following advantages: the phenolic resin composite waste leftover material is widely available; the process is simple, hardly causes secondary pollution, is favorable for protection of the environment, can realize reutilization of the waste material, changes the waste into the valuable and is capable of reducing production cost and increasing economic benefits; and the product produced after recycling and molding has excellent performance like high strength, heat resistance, dimensional stability and creep resistance and can be widely applied in the industries like the electromechanical industry, the ship industry, the aviation industry, the vehicle industry, the civil construction industry, the light industry, the textile industry and the industry of automobile interior decorative parts.
Description
Technical field
The present invention relates to a kind of recovery and molding process of phenol-formaldehyde resin composite waste recycling technique, particularly phenol-formaldehyde resin composite waste, be applicable to the recycling of automotive upholstery scrap stock.
Background technology
Resol (PF) is a kind of thermosetting resin conventional in industry.Fiber in thermosetting resin waste and resin can have two when recycling in purposes, one is as filler, adds in similar resin, can reduce costs; Join in thermoplastics, improve intensity, thermotolerance, dimensional stability, creep-resistant property etc.Another is the main raw material making goods, is uniformly mixed with tackiness agent, can be made into sheet material through molding.Due to its premium properties and wide application field, resol industry obtains and develops rapidly, and its consumption is increasing year by year, thereby produces the problem of a large amount of resol wastes in the urgent need to recycling.
The domestic and international Collection and utilization to phenolic resin waste has certain research at present, but simply single terms of settlement be there is no so far to the recycling problem of resol, its major cause is that the physics and chemistry character of phenolic resin starting material is varied, causes phenolic resin product to have specificity.But the interior trim in automotive industry gives up, resol is usually the waste material together with other Material cladding, and therefore, these waste materials can only be incinerated mostly, have both caused secondary pollution and have wasted available stock.Therefore, study the recycling of these waste materials, for turning waste into wealth, environment protection is very necessary.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point; thus a kind of resol compound waste leftover material convenient sources is provided; production technique is simple; not easily cause secondary pollution; be conducive to the recycling that protection of the environment realizes waste material; turn waste into wealth, and can production cost be reduced, be conducive to a kind of phenol-formaldehyde resin composite waste recycling technique of increasing economic efficiency.
Primary solutions of the present invention is achieved in that
Phenol-formaldehyde resin composite waste is added virgin pp, coupling agent and auxiliary agent Homogeneous phase mixing through pulverizing and makes compound by the present invention, compound is through heating, Heating temperature is: 185-195 DEG C, insulation to compound enters molten state, put into glasscloth in a mold, again molten state compound is moved into mold pressing in mould, the dwell time is: 3-5min, obtains goods finished product after cooling demoulding.
In the present invention, phenol-formaldehyde resin composite waste is: 28-45 % by weight, virgin pp are: 35-46 % by weight, coupling agent are: 10-12 % by weight, auxiliary agent: 5-8 % by weight, glasscloth: 5-6 % by weight;
In the present invention, virgin pp adopts particulate state; Glasscloth requires to adopt one deck or upper and lower two layers according to product strength;
In the present invention, soaking time is: 9-lOmin; Moving the material time is: 50-70s;
In the present invention, cooling temperature is below 70 DEG C;
In the present invention, die pressure is: 1.4-1.6MPa;
In the present invention, phenol-formaldehyde resin composite waste is pulverized and is: the particle of 0.8 ~ 2mm or sheet.
The invention has the beneficial effects as follows: resol compound waste leftover material convenient sources of the present invention, production technique is simple, not easily causes secondary pollution, be conducive to protection of the environment, the recycling of waste material can be realized, turn waste into wealth, and can production cost be reduced, be conducive to increasing economic efficiency; Through reclaiming shaping goods, there is the excellent performance such as high strength, thermotolerance, dimensional stability, creep-resistant property, the industries such as electromechanics, boats and ships, aviation, vehicle, civil construction, light industry, weaving and automotive upholstery can be widely used in.
Embodiment
The present invention below will be further described in conjunction with the embodiments:
Phenol-formaldehyde resin composite waste is laminated multi-layer matrix material, containing the impurity such as glass fibre and surface material distribution, disconnected from each other for these materials, will have very large difficulty.Fiber in thermosetting resin waste and resin join when recycling can as filler in thermoplastics, returnability is strong, not easily cause secondary pollution, so get automotive upholstery punching limit phenol-formaldehyde resin composite waste be in embodiments of the present invention: 28 % by weight, phenol-formaldehyde resin composite waste being ground into diameter is that 1mm particulate state adds in heating mixer with the form of filler, then thermoplastic material virgin pp 46 % by weight is added, silane resin acceptor kh-550 got by coupling agent, chemical name is: a glycidyl ether oxygen propyl trimethoxy silicane: 12 % by weight, ethylenebis stearyl EBS lubricating auxiliary agent is got: 8 % by weight, carrying out Homogeneous phase mixing is compound, then above-mentioned compound is placed in heating container and heats, Heating temperature is: 185 DEG C, insulation 9min enters molten state to compound, put into glasscloth in a mold: 8 % by weight: moved into above mould glasscloth by molten state compound again and carry out mold pressing, move material time controling at 50s, material matched moulds should be moved fast, performance and the outward appearance of goods can be ensured.For preventing shaping composite product from adhering on mould, and barrier film need be applied between goods and mould, so that goods are easy to deviate from from mould, ensureing that products surface quality and mould stand intact simultaneously.During operation, this releasing agent is distributed in mould equably, thus the demoulding just easily, do not damage mould.In the present embodiment, methyl-silicone oil releasing agent selected by releasing agent.Molten state compound is pressurize 3min in a mold, and die pressure is: 1.4MPa, and cooling temperature demoulding below 70 DEG C obtains goods finished product.The shape of goods finished product and performance by analysis with detection, it has the excellent performance such as high strength, thermotolerance, dimensional stability, creep-resistant property.
In the present invention, article shape or specification can make mould as required, and the starting material adopted are by being purchased in market, and the equipment of use is conventional equipment.
