Description
Technical field the present invention relates to a kind of preparation method of the preparation method that is used for the composite plate of skin, particularly a kind of rigid foam polyurethane and its using method.
The process of 200510045579.4 production rigid foam polyurethane a kind of application number is disclosed in the background technology prior art is, its process is that at first to make polymer sheet standby, the preparation method of polymer sheet is with after adhesive and the inorganic powder mixing, mixture and nonwoven are passed through the polymer sheet production line, produce polymer sheet, when with the polyurethane foaming machine tinuous production polyisocyanates and combined polyether being foamed into polyurethane plate then, polymer sheet is compound to the polyurethane plate two sides, produce Rigid foam polyurethane, not only insulating power is relatively poor to adopt the composite plate that this method makes, and in the work progress, need earlier with concrete or polymer mortar the body of wall levelling, this plate is sticked on the metope, construction is trouble again; The method for making method of a kind of skin heat-insulation layer of 01123683.3 a kind of application number is also disclosed in the prior art is, it is with polymer mortar polyphenylene heat insulation slab to be sticked on the body of wall earlier, scrape the first road putty on the styrofoam surface with polymer mortar again, spread glass cloth, scrape the second road putty again with polymer mortar, this kind heat-insulation layer not only heat insulation effect is poor, and when construction need carry out levelling to body of wall earlier, efficiency of construction is low.
Summary of the invention the objective of the invention is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of preparation method of new rigid foam polyurethane is provided, and this method not only manufacture craft is simple, and the composite plate high insulating effect of making, and is easy to use; The present invention also wants to provide the using method of this composite plate, and this method is simple to operate, the efficiency of construction height.
For realizing above-mentioned purpose of the present invention; the technical scheme that is adopted is: a kind of preparation method of rigid foam polyurethane; make heavy seal coat and interface in advance and strengthen the EPS plate; when adopting polyurethane foaming machine that polyisocyanates and combined polyether are foamed into hard-foam polyurethane sheet material then; heavy seal coat and interface are strengthened the two sides that the EPS plate is compound to hard-foam polyurethane sheet material, make rigid foam polyurethane.
Heavy seal coat of the present invention can adopt any in the following material:
A, inorganic powder and adhesive stirred after, force together the polymer sheet made from the mixture and the nonwoven of professional production line with inorganic powder and adhesive.
B, nonwoven is immersed in the adhesive, after soaking into fully, take out, then unnecessary adhesive is scraped off, dry the nonwoven fabric sheet of making.
The nonwoven of selling on c, the market.
Described interface reinforcement EPS plate can adopt any in the following EPS plate:
A, adhesive and inorganic powder mixed in the ratio of 0.7-1: 1.7-2 after, be sprayed at the one side of common EPS plate, the EPS plate of making after the oven dry.
B, the common EPS plate of making according to a conventional method.
In order to increase the service life of rigid foam polyurethane, the EPS plate of making of conventional method among the above-mentioned b, with density greater than 20Kg/ rice
3For good.
The present invention both can utilize the polyurethane foaming machine tinuous production; when polyisocyanates and combined polyether are foamed into hard-foam polyurethane sheet material; heavy seal coat and interface are strengthened the two sides that the EPS plate is compound to hard-foam polyurethane sheet material; make rigid foam polyurethane; also can adopt mould; heavy seal coat or interface reinforcement EPS plate are put in the mould; when with foaming machine polyisocyanates and combined polyether being foamed into hard-foam polyurethane sheet material in mould then; the EPS plate is strengthened at heavy seal coat and interface be compound to two of hard-foam polyurethane sheet material, make rigid foam polyurethane.
The using method of rigid foam polyurethane of the present invention is; earlier on metope, spray interfacial agents, with binding agent the one side that contains heavy seal coat in the composite plate is sticked on the metope then, strengthen the levelling of EPS plate with tooth brush polishing interface; smear polymer mortar more according to a conventional method, press grid cloth to get final product.
Described interfacial agents is for mixing the polymer of making by adhesive and inorganic powder in the ratio of 0.5-1.5: 1.0-2.5.
Composite plate of the present invention contains three layers; one deck is a heavy seal coat; one deck is the hard-foam polyurethane heat-insulation layer; another layer is strengthened the EPS plate for the interface; hard-foam polyurethane heat-insulation layer and interface are strengthened the EPS plate and are combined with each other; compared with prior art; heat insulating ability strengthens; utilize the higher performances of caking ability such as heavy seal coat and polymer mortar; can directly the one side that contains heavy seal coat be sticked on the body of wall during use; saved the operation of in the prior art wall face being carried out levelling; only strengthen carrying out whole levelling on the EPS plate at the interface with the tooth brush; thereby easy construction, efficiency of construction also improves greatly.
The specific embodiment is done further detailed description below in conjunction with specific embodiment to the present invention.
Make rigid foam polyurethane by following method:
1, make heavy seal coat in advance, followingly provided three kinds of heavy seal coats:
A, inorganic powder and adhesive mixed according to a conventional method after, force together with the mixture and the nonwoven of professional production line inorganic powder and adhesive, make polymer sheet, dry for standby.
B, nonwoven is immersed in the adhesive, after soaking into fully, take out, then unnecessary adhesive is scraped off, dry, it is standby to make nonwoven fabric sheet.
C, purchase the nonwoven of selling on the market, standby.
2, make the interface in advance and strengthen the EPS plate, followingly provided three kinds of interfaces and strengthen the EPS plates:
A, adhesive and inorganic powder mixed in the ratio of 0.7-1: 1.7-2 after, be sprayed at the one side of existing common EPS plate, the EPS plate is strengthened at the interface of making after the oven dry.
