Abstract
The invention belongs to the technical field of polyurethane foaming plastics, and in particular relates to a foaming material for a split solar heat-insulation board and a preparation method of the foaming material. Polyether polyol I, polyether polyol II, polyether polyol III, a catalyst I, a catalyst II, a catalyst III, silicone oil and a fire retardant are mixed uniformly to obtain the foaming material. Foam generated during the reaction process of the prepared foaming material and isocyanate has high compression strength, therefore the foam generated by the foaming material for the split solar heat-insulation board has high high-temperature size stability, and the foam is prevented from deforming at high temperature. Meanwhile, fire-retardant polyester is adopted to be matched with the fire retardant for use, so that the split solar heat-insulation board is ensured to have B2-grade fire-retardant performance. The method has the advantages of being scientific and reasonable, simplicity and easiness in operation and low production cost.
Description
Technical field
The invention belongs to urethane foam technical field, be specifically related to foamed material and preparation method thereof for a kind of splitting solar thermal baffle.
Background technology
Urethane foam is the foam article being made under whipping agent effect by polyether glycol and isocyanic ester, there is good heat-insulating property, mechanical property, electric property, acoustical behavior and chemical resistance, particularly there is excellent heat-insulating property, and be widely used in refrigerator, refrigerator-freezer, water-heater, cold storage plate, sandwich board, piping insulation, thermal container, etc. adiabatic heat-insulation field.
At present, splitting solar has two kinds by the material of thermal baffle, and the one, use rock wool, this material resistance to elevated temperatures is better, but thermal conductivity is high, and heat retaining property is poor; The 2nd, use polyurethane thermal insulation board, according to the size of goods, use the cutting of bulk bubble to form, because of the size less (thickness 0.015m) of splitting solar with thermal baffle, use in the process of bulk bubble cutting waste serious, thereby cause the cost of goods higher.
Summary of the invention
The object of this invention is to provide a kind of splitting solar thermal baffle foamed material, good heat preservation performance, good fluidity, production cost are low, and the present invention provides the preparation method of splitting solar thermal baffle with foamed material simultaneously, scientific and reasonable, simple.
Splitting solar thermal baffle foamed material of the present invention, by the raw material of following parts by weight, made:
Described polyether glycol I is that to take sucrose, glycerine be initiator, and propylene oxide ring-opening polymerization forms, functionality 5.5-6.0, and molecular weight is 700-750.
Described polyester polyol II is the polyester polyol based on phthalate anhydride, and functionality is 3, and molecular weight is 660.
Described polyether glycol III is to take glycerine as initiator, and propylene oxide ring-opening polymerization forms, and functionality is 3, and molecular weight is 1000.
Described catalyzer I is dimethylcyclohexylamine.
Described catalyst II is dimethyl benzylamine.
Described catalyzer III is quaternary ammonium salts catalyzer.
Described silicone oil is H-3303.
Described fire retardant is TCPP(tri-(chloro isopropyl) phosphoric acid ester).
Splitting solar thermal baffle of the present invention mixes polyether glycol I, polyester polyol II, polyether glycol III, catalyzer I, catalyst II, catalyzer III, silicone oil and fire retardant by the preparation method of foamed material, obtains.
Foamed material prepared by the present invention (A component) mixes and reacts by weight 1:1.5 with isocyanic ester (B component), prepares polyurethane rigid foam plastic.
A component is to carry out at normal temperatures, not only save energy but also reduce energy supply equipment and loaded down with trivial details operation.The environment-friendly type group polyurethane foamed material of being produced electric water heater by A, B component is also to carry out under normal temperature, normal pressure, and technique is simple, easy to operate, volatilize low, and without the three wastes, constant product quality, production cost is low.
Foamed material prepared by the present invention is used mould to prepare splitting solar thermal baffle, technique is simple, easy to operate, the foaming properties of preparation can be directly used in splitting solar, both can solve the poor problem of heat retaining property of rock wool, has also avoided the waste in production process, reduced production cost, and have low ODP, the advantage of low GWP, belongs to environmentfriendly products.
The present invention compared with prior art, has following beneficial effect:
The present invention adopts polyether glycol I and polyester polyol II, its advantage is that the combined polyether of production and the foam that isocyanate reaction generates have higher compressive strength, thereby guarantee that splitting solar thermal baffle has good high temperature dimensional stability with the foam of the preparation formation of foamed material, avoid foam at high temperature to produce distortion, adopt flame retardant polyester and fire retardant collocation to use simultaneously, guaranteed that sheet material has B2 level flame retardant properties; Adopt in addition suds-stabilizing agent H-3303, make the open bubble of the foam that generates few; Meanwhile, the mobility of this formula system is better, and the splitting solar thermal baffle of production can reduce materials amount 10-15%, and product once shaped simultaneously avoids reprocessing the cost increasing.
