Abstract

The present invention relates to a kind of automotive upholstery leftover pieces recovery and reuse technologies, belong to the recovery and molding process technical field of polyurethane composite waste.Polyurethane composite waste is crushed addition virgin pp, coupling agent and auxiliary agent and is uniformly mixed and made into mixture by the present invention, mixture is heated, heat preservation to mixture enters molten state, then molten state mixture is added in mold and is molded, and obtains product finished product after cooling demoulding.The compound waste leftover material convenient sources of the present invention, simple production process do not easily cause secondary pollution, are conducive to protect environment, are able to achieve the recycling of waste material, turn waste into wealth, and can reduce production cost, be conducive to increase economic efficiency;Recovered molding product has the excellent performances such as unique elasticity, wearability, low-temperature type, expandable, resistance to biodeterioration, can be widely applied to the industries such as electromechanics, ship, aviation, vehicle, civil construction, light industry, weaving and automotive upholstery.

Description

A kind of automotive upholstery leftover pieces recovery and reuse technology
Technical field
The present invention relates to a kind of automotive upholstery leftover pieces recovery and reuse technologies, belong to the recycling of polyurethane composite waste Molding technology thereof field.
Background technique
Polyurethane (PU) is common a kind of thermosetting plastics in industry, it is with multicomponent isocyanate and multi-hydroxy Closing object or polymer is raw material, and product is made through hybrid reaction.Can according to requirements, by feed change specification, kind and Formula synthesizes required product, just because of its excellent performance and is widely applied field, polyurethane industrial has obtained rapid hair Exhibition.It doubles within the consumption figure of world's polyurethane substantially every ten years, thereby producing a large amount of Methods for Polyurethane Wastes, there is an urgent need to return Receive the problem of utilizing.
Have certain research, but the recycling to polyurethane to the recycling of polyurethane waste material and utilization both at home and abroad at present Problem there is no simple single solution so far, the main reason is that the physics of urethane raw and chemical property are a variety of more Sample causes polyurethane product to have specificity.Carpet class back is made by bonding after can theoretically polyurethane scrap being crushed Lining is to recycle, but the amount of the polyurethane waste material recycled in this way is very limited, and have to the form of waste material, density it is special It is required that.In addition to this, polyurethane waste material can generate polyalcohol with thermal decomposition, burn the method for heat production in factory to recycle, but this Kind absorption method must use optimized burning condition, to reduce the generation of nitrogen oxides and amine as far as possible, and it is uneconomical.It is pure poly- If urethane foam use chemical recovering method to crack after as polyol starting material be the reasonable recovery method of comparison, however automobile work Waste polyurethane in industry is often the waste material being combined with each other with other materials, such as the punching leftover bits and pieces of material of car roof is multilayer Laminar composite, wherein foamed polyurethane is not contained only, but also containing impurity such as glass fibre and surface material distributions, these Substance is disconnected from each other, has very big difficulty.Pure polyurethane burn when calorific value be about 7000kcal/kg, between polyolefin with Between polyvinyl chloride, therefore, in no optional situation of other recoverying and utilizing methods, polyurethane waste material is crushed into beading, It recovers energy as fuel instead coal, oil and gas, is applied to roasting cement or power generation is also effective recovery method.But But secondary pollution is brought, during recovering energy, while the gas that also a large amount of generations are extremely harmful to environment.So It is worthless that the method for taking energy regenerating, which handles polyurethane waste material,.Therefore, these waste materials can only be incinerated mostly, both It causes secondary pollution and wastes available resources.Therefore, the recycling for studying these waste materials, for turning waste into wealth, environment Protection is very necessary.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of automotive upholstery leftover pieces recovery and reuse technologies, this is A kind of compound waste leftover material convenient sources, simple production process do not easily cause secondary pollution, are conducive to protect environment, be able to achieve The recycling of waste material, turns waste into wealth, and can reduce production cost, is conducive to returning for the polyurethane composite waste increased economic efficiency Receive moulding process.
Virgin pp is added, coupling agent, helps the technical scheme is that the present invention is crushed polyurethane composite waste Agent is uniformly mixed and made into mixture, and mixture is heated, heating temperature are as follows: 190-200 DEG C, heat preservation to mixture enters melting State, then mold molding, dwell time is added in molten state mixture are as follows: 4-5min obtains product finished product after cooling down demoulding.
Polyurethane composite waste in the present invention are as follows: 33-50 weight %, virgin pp are as follows: 35-48 weight %, coupling agent are as follows: 10-12 weight %, auxiliary agent: 5-7 weight %;Virgin pp uses graininess in the present invention;Soaking time in the present invention are as follows: 10- l1min;Move the material time are as follows: 60-70s;Moulding pressure in mold in the present invention are as follows: 1.5-1.6MPa;Polyurethane is multiple in the present invention It closes waste material to crush are as follows: the particle or sheet of 1~2mm;Cooling temperature of the present invention is at 60 DEG C or less.
The beneficial effects of the present invention are: the compound waste leftover material convenient sources of the present invention, simple production process do not easily cause two Secondary pollution is conducive to protect environment, is able to achieve the recycling of waste material, turns waste into wealth, and can reduce production cost, be conducive to improve Economic benefit;Recovered molding product has unique elasticity, wearability, low-temperature type, expandable, resistance to biodeterioration Etc. excellent performance, electromechanics, ship, aviation, vehicle, civil construction, light industry, weaving and automotive upholstery etc. can be widely applied to Industry.
Specific embodiment
The present invention will be further described in conjunction with the embodiments below:
Automotive upholstery punching side polyurethane composite waste is taken in the embodiment of the present invention are as follows: 41.5 weight % are compound useless by polyurethane The broken side length of feed powder is that 1.5mm sheet is added in heating mixer in the form of filler, and 42 weight % of virgin pp is then added, takes Silane resin acceptor kh-550: 11 weight %, ethylenebis stearoyl EBS lubricating auxiliary agent take: 6 weight % are uniformly mixed into mixed Close material;Then above-mentioned mixture is placed in heating container and is heated, heating temperature are as follows: 190 DEG C, heat preservation 9.5min to mixing Material enters molten state, then molten state mixture is moved into mold and is pressurizeed, and moves the control of material time in 60s.It is first adopted before moving material It is distributed evenly in mold with methyl-silicone oil release agent, is easy demoulding, does not damage mold.
Molten state mixture pressure maintaining 4min in a mold, die pressure are as follows: 1.5MPa, cooling temperature is in 60 DEG C or less demouldings After obtain product finished product.Equally there is unique bullet using molded article made of formula rate in the present embodiment, technological parameter The excellent performance such as property, wearability, low-temperature type, expandable, resistance to biodeterioration.
