Description
Technical field
The invention belongs to urethane foam technical field, be specifically related to a kind of splitting solar thermal baffle foamed material and preparation method thereof.
Background technology
Urethane foam is the foam article obtained under whipping agent effect by polyether glycol and isocyanic ester, there is excellent 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, the material of splitting solar thermal baffle has two kinds, and one is use rock wool, and this material resistance to elevated temperatures is better, but thermal conductivity is high, and heat retaining property is poor; Two is use polyurethane thermal insulation board, according to the size of goods, uses the cutting of bulk bubble to form, and because of the size of splitting solar thermal baffle less (thickness 0.015m), uses waste in the process of bulk bubble cutting serious, thus causes 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, invention also provides the preparation method of splitting solar thermal baffle foamed material, scientific and reasonable, simple.
Splitting solar thermal baffle foamed material of the present invention, be made up of the raw material of following parts by weight:
Described polyether glycol I is that propylene oxide ring-opening polymerization forms, functionality 5.5-6.0 with sucrose, glycerine for initiator, 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 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).
Polyether glycol I, polyester polyol II, polyether glycol III, catalyzer I, catalyst II, catalyzer III, silicone oil and fire retardant mix by the preparation method of splitting solar thermal baffle foamed material of the present invention, to obtain final product.
Foamed material (component A) prepared by the present invention and isocyanic ester (B component) mix by weight 1:1.5 and react, and namely prepare polyurethane rigid foam plastic.
Component A is carried out at normal temperatures, not only save energy but also reduce powering device and loaded down with trivial details operation.The environment-friendly type group polyurethane foamed material being produced electric water heater by A, B component is also carry out under normal temperature, normal pressure, and technique is simple, and easy to operate, volatilize low, without the three wastes, constant product quality, production cost is low.
Foamed material prepared by the present invention uses 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 problem of the heat retaining property difference of rock wool, it also avoid the waste in production process, reduce production cost, and there is low ODP, the advantage of low GWP, belong 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 produced and the foam that generates of isocyanate reaction have higher compressive strength, thus ensure that the foam that the preparation of splitting solar thermal baffle foamed material is formed has good high temperature dimensional stability, foam is avoided at high temperature to produce distortion, adopt flame retardant polyester and fire retardant to arrange in pairs or groups to use simultaneously, ensure that sheet material has B2 level flame retardant properties; Adopt suds-stabilizing agent H-3303 in addition, make the open bubble of the foam of generation few; Meanwhile, the mobility of this formula system is better, and the splitting solar thermal baffle of production, can reduce and use doses 10-15%, simultaneously product once shaped, avoids carrying out reprocessing the cost increased.
