Abstract
The present invention relates to a special product which is manufactured from plastics or plastic state substances, and the special product is used for building elements. The special product is composed of a plastic-steel hollow box and a filler, wherein the filler is prepared from 57% to 80% of EPS, 10% to 20% of plastic, 3% to 5% of resin adhesive, 1% to 5% of flame retardant, 3% to 10% of hardening agent and 1% to 3% of anticorrosive agent; the filler is mixed and then is jetted into the prefabricated plastic-steel hollow box, and the filler and the box are pressurized to be formed; the formed product is cut accordingly to desired specifications, and fire retardant paint is sprayed on the surface of the formed product; a processed solid plastic-steel section can be used for doors, windows, wall plates, floors, etc.; compared with common plastic steel, the processed solid plastic-steel section has the advantages of high strength, no deformation at a high temperature, fire retardancy, etc.
Description
The present invention relates to a kind of with plastics or with the particular product that is used for building slab of the material production of plastic state.
Be used widely with material etc. with Plastic steel door, plastic-steel window, wallboard, floor, decoration engineering that the plastic-steel material is made.But the plastic-steel building product of Shi Yonging is open core type in the market, and insufficient strength as the weight bump, easily produce and break, and chance high temperature is yielding, and the work-ing life of product is short.
Purpose of the present invention aims to provide a kind of intensity height, it is not yielding to meet high temperature, and can be fire-retardant, aging-resistant solid plastics-steel shape and manufacture method thereof.
The said solid plastics-steel shape of the present invention comprises the hollow box of plastic-steel (being hollow plastic-steel pattern) and is filled in the interior resin material of the hollow box of plastic-steel, the component of said resin material and proportioning are lightweight foam material polystyrene (EPS) 57%～80%, best 70%; Plastics 10%～20%, best 15%; Resin cement 3%～5%, best 4%; Fire retardant 1%～5%, best 3%; Hardness reinforcer 3%～10%, best 6%; Inhibitor 1%～3%, best 2%.Said plastics are at least polyvinyl chloride (PVC), polystyrene (PS), high density polyethylene(HDPE) (HI-PE), acrylonitrile-butadiene styrene copolymerized resin (ABS), acrylonitritrile-styrene resin (AS), a kind of in the polypropylene (PP); Resin cement is ethene-vinyl acetate emulsion copolymer (an EVA latex); Fire retardant is antimonous oxide (Sb
2O
3); Hardness reinforcer is Resins, epoxy or polyamide resin; Said inhibitor is tribasic lead sulfate (lead sulfate tribasil).
The manufacturing technology steps of the said solid plastics-steel shape of the present invention is as follows: 1. extrude the hollow box of plastic-steel with the extrusion molding machine, and under 150 ℃～220 ℃ temperature through the model extrusion forming; 2. lightweight foam material polystyrene (EPS), plastics are pulverized, proportioning by EPS 57%～80%, plastics 10%～20%, resin cement 3%～5%, fire retardant 1%～5%, hardness reinforcer 3%～10%, inhibitor 1%～3% cooperates each component then, mixed material is drying to 80 ℃ again, to remove moisture content; 3. the mixing potting resin injection of material after will handling is gone in the hollow box of plastic-steel, is forced into 454～1362Kg extrusion molding again; 4. carry out cutting by required specification; 5. surface treatment promptly sprays fire retarding paint on the surface of solid plastics-steel shape, and toast 10～30min under 60～100 ℃ temperature, cooling back packing.
The general plastic-steel section bar of its strength ratio of solid plastics-steel shape provided by the invention is doubled, and (solid plastics-steel shape uses every square metre of 300～1000KgS of engineering, general plastic-steel section bar uses engineering every square metre 150～500KgS), indeformable under 60～80 ℃ of temperature, and general plastic-steel section bar just has the modification sign under 40～60 ℃ of temperature.And owing in the material of filling, add fire retardant, and in the spraying of plastic-steel section bar surface fire retarding paint, make it have anti-flaming function, and Alfalfa Extract, under ultraviolet light 20～30 years aging, embedded can 30～50 years aging, long service life.And employed EPS, plastics etc. can adopt produces EPS, the scrap stock in the plastics, substandard products.Not only the energy can be saved but also the offal pollution on the environment can be avoided.In addition, also can be as required, the content of EPS and plastics makes its section bar proportion close with the proportion of various natural timbers in the change packing material.
The present invention will be further described below by embodiment.
Embodiment 1: at first with the extrusion molding machine with the hollow box extrusion molding of plastic-steel, and in 200 ℃ through the model extrusion forming, get lightweight foam material EPS 700Kg, plastics are after PVC material 150Kg pulverizes, add ethene-vinyl acetate emulsion copolymer (EVA latex) 40Kg, antimonous oxide 30Kg, Resins, epoxy 60Kg and tribasic lead sulfate 20Kg, mix the back oven dry to 80 ℃, packing material after mixing is gone in the hollow box of plastic-steel with the pneumatic press accelerating jetting, be forced into 44.485MPa～133.455MPa extrusion molding by press, to be filled to solid plastic-steel section bar is cut into door and window by cutting machine framework then, spray the last layer fire retarding paint with the vacuum pressure paint spraying machine on the surface of plastic-steel section bar at last, drop into pusher baking box after spraying paint again and heat to 90 ℃ of baking 20min cooling back packing.Plastic-steel section bar proportion after the processing is similar to the proportion of weedtree.
Embodiment 2: at first with the hollow box of extrusion molding machining plastic-steel, get EPS scrap stock 800Kg, plastics are PVC, PS, ABS, HI-PE, AS, the scrap stock of PP etc., substandard products mixing material 100Kg pulverizes, add ethene-vinyl acetate emulsion copolymer 30Kg, antimonous oxide 10Kg, polyamide resin 50Kg and tribasic lead sulfate 10Kg, put into after the mixing and dry again to 80 ℃ after high-speed mixer mixes, packing material after mixing is gone in the hollow box of plastic-steel with the oil press accelerating jetting, complete processing is with embodiment 1, and the solid plastics-steel shape after the processing can be used for doing door leaf or wallboard.
