Description

A kind of Novel lightweight moulding or component and manufacture method thereof
Technical field
The present invention relates to a kind of lightweight moulding or component, particularly to one about this lightweight moulding or The manufacture method of component.
Background technology
Along with the raising of people's living standard, the commodity demand of room exterior wall construction material is got more and more, decoration Component is a kind of building subassembly in building decoration and fitment details engineering, and it plays important modification for the attractive in appearance of building.
Existing decoration element or lines can be roughly divided into two kinds, and one is cement or gypsum material, and it uses mould pre- Making type, this component consumptive material is many, weight big, transports, installs inconvenience, if coming off from building, can produce safety greatly hidden Suffer from, and this component position can not carry out effective isothermal holding;One is lightweight member, and it uses expanded material to make, although matter Gently, but all there is the problems such as structural strength is low, fragile, fire protecting performance is poor, and the bubble generation member overwhelming majority uses the side gluedd joint Formula is directly bonded in surface of wall, big by external environment influence factor, can produce the phenomenon of degumming, use after long-time use Life-span is low.
Summary of the invention
The present invention provide a kind of lightweight, structural strength is high, the decoration element of difficult drop-off, in addition it is also necessary to this dress a kind of is provided The manufacturing process of decorations component.
The present invention solves the problem described by background technology by the following technical solutions: Novel lightweight moulding or Component, it includes lightweight foaming body and the metallic framework for enhanced foaming body, and metallic framework has a strip plate body, should The back side of plate body is provided with for being connected fixing connector or attachment structure with building decoration support;The positive Middle face of plate body is even Connecing and be fixed with a built-in fitting extended along strip board long axis of body direction, the cross section of this built-in fitting is " J " shape of a front end bending, " J " shape rear end of built-in fitting is connected fixing with plate body front vertical, and the bending end of built-in fitting is along the short-axis direction of strip plate body Bending;Non-dogleg section at built-in fitting has pod apertures, is provided with longitudinal rein forcement between built-in fitting and plate body;Foaming body bag Being rolled in outside the built-in fitting of metallic framework, the back side of foaming body is close to the front of strip plate body, and the back side of foaming body and strip Transition adhesive layer is set between plate body front;A side end face of foaming body is provided with the convex extended along foaming body edge Muscle, is provided with the detent extended along foaming body edge on the opposite side end face of foaming body.More specifically, described foaming body Both ends outer surface be provided with one after spraying area, the foaming body of this rear spraying area is gradually reduced to end thickness from middle, After and, the foaming body thickness difference of spraying area is between 0.5 ~ 2mm, and the non-post spraying area outer surface at foaming body is coated with colored spray Layer of sand.
Also provide for a kind of manufacturing above-mentioned Novel lightweight moulding or the manufacture method of component, the steps include:
S1 makes foaming mould, and foaming mould includes left and right die, forms one and just can accommodate after this left and right die matched moulds The die cavity of foaming body appearance profile, left and right die has the passage connected with die cavity;The medial wall of right die is arranged There is a closing-type cavity edge and just can embed the positioning pit of strip plate body, receiving connector is set in the bottom of this positioning pit Or the receiving chamber of attachment structure, and left and right die matched moulds seam flush with the upper edge of positioning pit;
S2 selects foaming raw material, selects diameter expandable polystyrene resin particles between 0.07 ~ 0.1in, and its foaming Agent content controls between 5.4 ~ 5.6%wt, and flame retardant agent content controls at 0.9 ~ 1%wt;
S3 prefoam, carries out steam direct heating to expandable polystyrene resin particles, and heating-up temperature, at 98 ~ 102 DEG C, is pressed Power is between 0.03 ~ 0.04MPa, and the prefoam persistent period is 3S;
S4 ripening, is placed in the expandable polystyrene resin particles after prefoam in air, and curing temperature controls 22 ~ 26 DEG C, the curing time is 7 ~ 8h;
S5 pretreatment, at the plate body front surface coated transition binding agent of metallic framework, transition binding agent uses one-component polyurethane Stick, the composition component of this adhesive in parts by mass: polyether polyol 22.3 ~ 23.3;Polymethylene multi-phenenyl isocyanate 23.4~24.0;Ethylenediamine: 0.01;Diethanolamine: 0.048;Dichloromethane: 57.8 ~ 60;
S6 places metallic framework, the strip plate body of metallic framework is embedded in positioning pit, and make the plate body back side connector or Attachment structure is positioned at receiving intracavity, and the built-in fitting in plate body front is positioned at the die cavity of mould;
S7 secondary frothing forming, coats in 2 ~ 4min after transition binding agent, by the expandability after ripening in above-mentioned steps S2 Polystyrene resin beads imports in the die cavity of mould, and the consumption of expandable polystyrene resin particles is at 18 ~ 20kg/m3, logical Cross passage in die cavity, be passed through the steam of 0.55 ~ 0.65MPa, and make temperature rise to 140 ~ 150 DEG C, keep 9 ~ 10min, natural Cooling molding obtains connecting the foaming body having metallic framework;
S8 sprays, and the non-post spraying area outer surface at foaming body is coated with color sand blasting layer.
The invention have the advantage that
(1) decoration of the present invention uses polystyrol foam material to make, and its light weight, high insulating effect, this position need not Carry out Additional insulation process again, the most easy to crack;And the built-in fitting of metallic framework is built in foaming body, board body part is divided and is arranged on The sidewall of foaming body is also connected with built-in fitting, and both strengthen the structural strength to foaming body that cooperates, and decoration element is not Fragile;
