Universal day by day along with plastics, the waste of the Plastic Packaging Materials in various industrial or agricultural and the life, mulch film, goods etc. has become the main constituent of city and rural garbage.Make that these are rotten, the modification of aged waste makes it as binding agent, the refuse that is used for solidifying other industries will be at one stroke two environmental practices.
The present external existing novel material made from polymkeric substance and granular aggregate, their raw material all is some new polymkeric substance and mineral aggregates, has very strong surfactivity, needn't carry out surface treatment to it.Disclosed a kind of polymer concrete in the patent of EP0062373 for example, its material characteristic are to adopt the thermosetting polymer of 3-5% and the mineral aggregate that adopts 85-97%.Polymkeric substance is unsaturated polyester or the vinyl ester resin mixture that contains free group linking agent, and these all are the very strong binding agents of well-known bonding force.Its manufacturing process comprise raw material with machinery method mix, mixed raw materials is poured in the model with pigment, in 0-200 ℃ of scope the mixture cures in the model.Disclosed in the patent of US3070557 is the mixture that adopts the usefulness of paving the way that the mineral aggregate of the thermoplastic polymer of 1-10% and 90-99% is composited.Thermoplastic polymer also is such as organic binder bonds such as polyethylene, polypropylene.Process characteristic is polymkeric substance and the aggregate that heat is mixed preheating, compacting subsequently, hardening by cooling.More than the common feature of these prior aries be that raw material does not need reactivate to handle; Adopt well-known organic polymer as tackiness agent; Be composited with traditional equipment; The material of making all is lower some material of construction such as concrete of performance.
What the present invention relates to is the method that makes various industrial or agricultural, civilian materials recycling, modification, is equipped with additive with waste material after regeneration, the modification as raw material and is composited, and has some timber, the non-metallic material of steel performance.
The raw material of this matrix material comprises three classes; The first kind accounts for more than 95% of weight, is various industrial or agricultural solid waste; Second class accounts for the 0.1-3% of weight, is the cheap raw material of producing from various waste liquids; The 3rd class accounts for the 0.1-3% of weight, is general industrial chemicals.
In the above-mentioned first kind raw material, it is various solid slags that 50-80% is arranged, as cast waste sand, the leftover bits and pieces of metallurgical slag, fuel waste residue, mining slag, chemical sludge and animal hair, shredded paper rag, plant fibre slag, shredded rubber, these bits etc.They are intended for particle strongthener and fiber reinforced material in the matrix material, or are called aggregate.
In the above-mentioned first kind raw material, it is thermoplastic waste or used plastics that 20-50% is arranged, as depleted polyethylene agricultural mulching and packing bag, and depleted polypropylene woven bag and rope band, the depleted polrvinyl chloride product, depleted frothing polystyrene wrapper etc.They are intended for the body material in the matrix material, or are called binding agent.
Because the above-mentioned first kind raw material more than 95% that accounts for weight is the waste residue material, and be again to come from all trades and professions, so in its surface with various organic or inorganic impurity, in addition the specific surface area of these slag charges also has great difference.Like this, had a strong impact on waste residue material, with combining of body material as particle or fiber reinforced material; Influenced the consumption of additive; Influenced of the absorption of waste residue material surface to additive, and the degree that chemical reaction takes place, influenced the hot flowability of matrix material etc., so, remove the inert impurities (should be less than 3%) of waste residue material surface attachment, and make it have (0.01-10 meter of certain specific surface area
2/ restrain) and certain temperature (200-400 ℃).
In order further to solve because of the bonding force between waste residue material and the plastic waste reasons such as not enough and plastic waste is aging to variety of problems such as low, the hot flowability of the mechanical property that matrix material brings are not good, the present invention is after making the waste residue grain remove the surface inertness layer, adopted and a series ofly can play the surfactivity effect, the additive of group sequestering action.Here it is the above-mentioned second class raw material that accounts for weight 0.1-3%.They all are the cheap raw materials of producing from various waste liquids.It is the sulfonated lignin of producing from papermaking wastewater that 30-70% is wherein arranged, and it is ancient marlon resin of producing from coke tar refuse etc. that 30-70% is arranged.
Because various waste residue material major parts are dark, then cost is too high if add pigmented tinting; Again because the surface hardness of the matrix material that waste residue, plastic waste are made is undesirable, so, the present invention has adopted a kind of surface multiple layer technology, promptly answers the last layer thermosetting material again on the useless plastic composite materials of thermoplastic waste residue.Its principle is: thermoplastic material will be emitted heat when sclerosis, this part heat is just in time all absorbed by topped powder thermosetting on thermoplastic material, cause the powder sclerosis to form a hard thin layer, stick on waste residue, the useless plastic composite materials with killing.The color and luster of this composite bed can be by adding pigment and regulated at will in powder thermosetting.If heat is very few, then powder thermosetting can not harden, or is local hardening; If heat is too much, then powder thermosetting can be burnt.So can composite bed successful key be, according to the specific heat capacity and the thermal conductivity of starting material, moulding stock; Stiffening temperature and time according to required to certain thickness thermosetting material reach thermal equilibrium, get final product.Above-mentioned the 3rd class raw material that accounts for weight 0.1-3%, this thermosetting material that just is meant is as industrial chemicals and a small amount of Synolac such as versicolor powdery aminoresin.Compound one-time formed technology of thermoplastic material and thermosetting material while that Here it is.
