Description

A kind of recovery and molding process of phenol-formaldehyde resin composite waste
Technical field
The present invention relates to a kind of recovery and molding process of phenol-formaldehyde resin composite waste, specifically be used for the recycling of automotive upholstery leftover pieces.
Background technology
Phenolic resins (PF) is a kind of thermosetting plastics commonly used in the industry.Purposes fiber in the thermosetting plastics discarded object and resin can have two when recycling aspect, the one, as filler, add in the similar resin, can reduce cost; Join in the thermoplastic, improve intensity, hear resistance, dimensional stability, creep-resistant property etc.Another is a main material of making goods, mixes with adhesive, can be made into sheet material through molding.Because its premium properties and application fields, phenolic resins industry has obtained developing rapidly, and its consumption figure has produced the problem that a large amount of phenolic resins discarded objects presses for recycling thus increasing year by year.Domestic and international at present recovery and the existing certain research of utilization to phenolic resin waste, but the recycling problem of phenolic resins still there is not simple single solution so far, its main cause is that the physics and the chemical property of phenolic resins raw material is varied, causes the phenolic resins product to have specificity.Yet the useless phenolic resins of the interior trim in the auto industry usually is the waste material that is combined with each other with other material, and therefore, these waste materials can only both have been caused secondary pollution also to waste available resources by burning disposal mostly.Therefore, study the utilization again of these waste materials, for turn waste into wealth, environmental protection is very necessary.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point; thereby provide a kind of phenolic resins compound waste leftover material convenient sources; production technology is simple; be difficult for causing secondary pollution; help protecting environment, can realize the utilization again of waste material, turn waste into wealth; and can reduce production costs the recovery and molding process of a kind of phenol-formaldehyde resin composite waste that helps increasing economic efficiency.
Main solution of the present invention is achieved in that
The present invention evenly is mixed and made into compound with phenol-formaldehyde resin composite waste through pulverizing adding virgin pp, coupling agent and auxiliary agent, compound is through heating, heating-up temperature is: 185-195 ℃, be incubated to compound and enter molten state, in mould, put into glass fabric, again the molten state compound is moved into mold pressing in the mould, the dwell time is: 3-5min obtains the goods finished product behind the cooling demoulding.
Phenol-formaldehyde resin composite waste is among the present invention: 28-45 weight %, virgin pp are: 35-46 weight %, coupling agent are: 10-12 weight %, auxiliary agent: 5-8 weight %, glass fabric: 5-6 weight %;
Virgin pp adopts graininess among the present invention; Glass fabric requires to adopt one deck or two layers up and down according to product strength;
Temperature retention time is among the present invention: 9-10min; Moving the material time is: 50-70s;
Chilling temperature is below 70 ℃ among the present invention;
Die pressure is among the present invention: 1.4-1.6MPa;
Phenol-formaldehyde resin composite waste is pulverized and is among the present invention: the particle of 0.8~2mm or sheet.
Compared with the prior art the present invention has the following advantages:
The compound waste leftover material convenient sources of phenolic resins of the present invention, production technology is simple, is difficult for causing secondary pollution, helps protecting environment, can realize the utilization again of waste material, turns waste into wealth, and can reduce production costs, and helps increasing economic efficiency; Goods through reclaiming moulding have good performances such as high strength, hear resistance, dimensional stability, creep-resistant property, can be widely used in industries such as electromechanics, boats and ships, aviation, vehicle, civil construction, light industry, weaving and automotive upholstery.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
Embodiment one:
Phenol-formaldehyde resin composite waste is the laminated multi-layer composite, contains impurity such as glass fibre and surface material distribution, and is disconnected from each other these materials, has very big difficulty.Fiber in the thermosetting plastics discarded object and resin join when recycling and can be used as filler in the thermoplastic, recuperability is strong, be difficult for causing secondary pollution, so get automotive upholstery punching limit phenol-formaldehyde resin composite waste in embodiments of the present invention be: 28 weight %, it is in the form adding heating mixer of 1mm granulated with filler that phenol-formaldehyde resin composite waste is ground into diameter, add thermoplastic virgin pp 46 weight % then, coupling agent is got silane resin acceptor kh-550, chemical name is :-glycidyl ether oxygen propyl trimethoxy silicane: 12 weight %, ethylenebis stearoyl EBS lubricating auxiliary agent is got: 8 weight % evenly are mixed into compound; Then above-mentioned compound is placed in the heating container and heats, heating-up temperature is: 185 ℃, insulation 9min enters molten state to compound, in mould, put into glass fabric: 8 weight %: again the molten state compound is moved into mould glass fabric top and carry out mold pressing, moving the material time is controlled at 50s, the material matched moulds should be moved fast, the performance and the outward appearance of goods can be guaranteed.For the composite product that prevents moulding adheres on the mould, and need between goods and mould, to apply barrier film,, guarantee that simultaneously products surface quality and mould are excellent from mould so that goods are easy to deviate from.During operation this releasing agent is distributed in the mould equably, thereby the demoulding is not decreased mould just easily.Releasing agent is selected the methyl-silicone oil releasing agent for use in the present embodiment.The molten state compound is pressurize 3min in mould, and die pressure is: 1.4MPa, chilling temperature obtains the goods finished product at demoulding below 70 ℃.The shape of goods finished product and performance by analysis with detection, it has good performances such as high strength, hear resistance, dimensional stability, creep-resistant property.
Article shape or specification can be made mould as required among the present invention, and the raw material that adopted are purchased by market, and the equipment that uses is conventional equipment.
