Abstract
The present invention discloses a foaming shaped sofa which can be provided with a skeleton or without a skeleton. The foaming shaped sofa is a high rebound foam sofa which is shaped by the flexible high rebound foaming formula and the technology of the high activity polyether of polyurethane and stem grafting polyether, wherein the foaming shaped sofa with different position density and different compression load performance can be manufactured by selecting foaming formulas with different density and different hardness according to different stress of each position of the sofa. The foaming shaped sofa has the advantages of convenience, easy production, material saving, time saving, labor saving, firmness, durability, comfort, softness and low sound, and is favorable for washing and sterilization.
Description
The present invention relates to sofa, referring in particular to polyurethane high activity polyether and graft polyether is primary raw material, skeleton being arranged or the method for the exoskeletal foaming-shaped sofa of frame is arranged of making.
Mostly existing sofa is that with wooden frame or metal tube be framework, is being added materials such as the rope made of hemp, burlap by layer with spring and forms elastic inner layer then.This class sofa manufactures and both bothers time-consumingly, shaky again, and it is loose that spring often takes place, and the sofa seat surface sink, and makes the sofa seat surface become a hole, sits up both uncomfortable and seems not attractive in appearance.And from another point of view, to be particular about succinct practical fast viewpoint now, this class sofa also presents the problem that it is not inconsistent fashion.
The object of the present invention is to provide a kind of preparation method of foaming-shaped sofa, said foaming-shaped sofa can be skeleton to be arranged and the exoskeletal foaming-shaped sofa of frame is arranged, and it is the high rebound foam sofa with polyurethane high activity polyether and graft polyether soft high-resilience foaming formulation and the direct foaming of technology.
Wherein, can select for use the foaming formulation of different densities and different hardness to make the different parts density foam sofa different according to the stressed difference in each position of sofa among the present invention with the compression load performance, can be that quadric injection mould also can be polyurethane high activity polyether and two kinds of prescription injection mouldings simultaneously of graft polyether during production, wherein requirement guarantees that the hardness of the seat surface of this sofa is higher than the hardness of backrest and both sides.
Wherein, the prescription that can be used as the seat surface material of the present invention can be:
Formulation ratio 1 (ratio of weight and number) proportioning 2 (ratios of weight and number)
Niax?polyol?XJ-48 100 100
Water 2.5 3.2
Niax 1 (amine catalyst) 0.08 0.04
Silicone?L-5307 0.4 0.4
(foam stabiliser) stannous octoate 0.9 0.965/35TDI (index) (110) (110)
Wherein, the prescription that can be used as the material of the back side and both sides of the present invention can be: formulation ratio 1 (ratio of weight and number) proportioning 2 (ratio of weight and number) Niax polyol XJ-48 100 100 water 2.4 2.8DEOA 1.0 1.0Niax A-1 0.08 0.08Silicone L-5307 0.4 0.4 (foam stabiliser) stannous octoate 0.15 0.1580/20TDI (index) (110) (110)
In addition, sofa of the present invention also can be selected the material of following prescription: foaming formulation data Desmsphen 3900 (high activity polyether, hydroxyl value 35) 100 water 2.1 diethanol amine 0.4CRTEGOL 204 3.0Dabco 33LV 0.1Niax A-1 0.15 dibutyltin dilaurates (DBTL) 0.03 foam stabiliser TEGOSTAB B4113 1.0TDI80/20 38.2 indexes 100
The skeleton foaming-shaped sofa is arranged, it is characterized in that: the at first shape of the sofa of design and pattern, make the skeleton of sofa according to these shapes and pattern then, and make the sofa shape mould identical of required acquisition with pattern.The skeleton of sofa is placed in the mould, and to make it fill the power foaming in the quantitative injection mould of the soft foaming raw material of high resilience be that the whole foamings of a kind of formula material have skeleton foaming sofa having.
The exoskeletal foaming-shaped sofa of frame is arranged, it is characterized in that: need not to design and produce Frame of sofa, the mould of the sofa pattern of design and the housing of sofa, making it fill the power foaming in the injection mould that needed foaming raw material is quantitative is that the whole foamings of a kind of formula material are for there being the exoskeletal foaming sofa of frame.
According to the stressed difference in each position of sofa, be necessary to select for use the foaming formulation of different density and hardnesses to make it to produce the different parts density foaming sofa different with compression load with technology, the people is sitting in feels more comfortable on the sofa.
This foaming also can be the partial foaming moulding.When local foaming, be necessary sometimes with as the material that fine quality and glamour are arranged in the framework material as: copper pipe, stainless steel tube, the timber of high-quality etc. partly expose (not foaming) and make its whole foaming sofa more charming.
Selected foaming raw material and foaming formulation and foaming technique all adopt foaming raw material and foaming formulation and technology.These raw materials and foaming formulation all need possess resilience, software function.Polyurethane high activity polyether and graft polyether soft high-resilience expanded material and prescription are selected for use when first-elected for now.
As the skeleton of foaming sofa and the material of housing can be the synthetic again of waste or used plastics, various timber, steel, non-ferrous metal etc.
Pattern as foaming sofa forming mould can be Protean; Material should be selected in the aluminum alloy materials that is applicable to cold-curing and the polyurethane the obtainable reinforced plastics of hard foaming technique institute etc. basically for use.
Should be taken into account the injection needs of different densities and hardness foaming formulation during designing mould, can separate making and then fit together.The raw material of the prescription of such two kinds of different densities and hardness can be distinguished injection simultaneously.
The production technology of sofa provided by the present invention is:
(1). mould is also made in design, stays injecting hole and deflation hole, can not stay the deflation hole when wherein putting in order the skin molding; The material of described mould can be selected reinforcing materials such as aluminium alloy, epoxy resin.
(2). design is also made Frame of sofa, wherein should make according to whole foaming or partial foaming; The material of described Frame of sofa can be selected rigid polyurethane foams, multiple plastics, timber, stainless steel tube, copper pipe etc.
(3). injection moulding: place the Frame of sofa that makes in the sofa mould or as required part is exposed; Selected above-mentioned high activity polyether type or the various components in the graft polyether type soft high-resilience foaming formulation after fully mixing, are annotated in the progressive die tool by the preformed hole on the mould mixing head in proportion quantitatively, make its fully foaming in mould, through operations such as slaking, demoulding, cleaning, finishings, the production technology of foaming-shaped sofa promptly is achieved.
The wherein abundant foaming of high activity polyether or graft polyether section bar material, slaking condition and foaming of the prior art, slaking condition are identical.
Above technology provided by the present invention can be made sofa, seat, bed accessory etc., as includes skeleton or the exoskeletal sofa of frame is arranged.
This kind sofa provided by the present invention, easy easy production, economize material, save time, the saving of labor, sturdy and durable, comfortable, soft, sound is little, should clean, should sterilize.
