Abstract
The present invention provides a kind of new polyurethane external wall insulation for mixing white carbon, and production technology is as follows：1) will be polyether polyol, isocyanates mixing and stirring standby；2) by step 1) process after mixed material carry out being poured on glass mat；3) glass mat after cast is covered into layer of glass felt, and rapid pressing and forming again；4) by step 3) process after glass mat carry out the foaming ripening sizing of polyurethane, then Jing deburrings, cutting, cutting process, you can.By the white carbon black raw material added between glass mat, its overall structural strength, and one-shot forming can also be improved while anti-flammability is improved, directly be pressed, be easy to processing.Then the foaming ripening sizing of polyurethane is carried out, whole Making programme is enormously simplify, whole technological operation is convenient, application can be further generalized in actual plant produced.
Description
Technical field
The present invention relates to warming plate field, and in particular to a kind of new polyurethane external wall insulation of incorporation white carbon.
Background technology
With present industrialization, informationalized development, people in enjoy that science and technology brings convenient while, also for life product
The pursuit more and more higher of matter.
In present life, increasing people is lived in city, and the population density in city is also sharply increased, while
The people lived in city, the improvement of living environment are also the important improvement of people life style.Particularly in the cold winter
In season, in order to preferably keep indoor temperature, warming plate material can be adopted during actual building construction in a large number, and hard is poly-
The use of urethane external wall insulation is more popularized.
But present warming plate major part use with polystyrene resins as raw material plus other supplementary materials with
Poly- inclusion, by heating mixing simultaneously injecting catalyst, then extrusion molding extrusion molding and the rigid foam plate that manufactures, have
Moistureproof, water resistance, can make reduction building envelope thickness, so as to increase indoor usable floor area.But adopt now
Warming plate inside the foaming agent that adds etc., easily there is nature when temperature is raised, affect safety, while the structure of entirety
Intensity is not high, and big for the insulating plate structure density of some electrodeless good flame retardation effects, high cost, and strong influence is protected
The preparation and processing of warm plate.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of new polyurethane external wall insulation for mixing white carbon,
So that the preparation of warming plate is more convenient, while improve its structural strength.
To realize object above, the present invention is achieved by the following technical programs：
A kind of new polyurethane external wall insulation for mixing white carbon, production technology are as follows：
1) will be polyether polyol (white to expect), isocyanates (black material) mixing and stirring standby；
2) by step 1) process after mixed material carry out being poured on glass mat；
3) glass mat after cast is covered into layer of glass felt, and rapid pressing and forming again；
4) by step 3) process after glass mat carry out the foaming ripening sizing of polyurethane, then Jing deburrings, cutting, cut
Cut process, you can.
Preferably, described step 1) in temperature control at 85-103 DEG C, pH value 5-6, mixing time are 4-6 hours.
Preferably, described step 2) in poured using Quick uniform note, and control note and pour temperature for 65-80 DEG C.
Preferably, described glass mat is refractory material.
Preferably, described step 4) in foaming ripening temperature be 35-45 DEG C.
Preferably, the control time of described foaming ripening sizing is 2-4 hours.
The invention provides a kind of new polyurethane external wall insulation for mixing white carbon, by between glass mat
The white carbon black raw material of addition, uniform addition white carbon alleviate polyurethane thermal insulation board weight, while increased the anti-flammability of product
Can, and one-shot forming, directly press, be easy to processing.And add the glass mat of white carbon molding before foaming ripening
Add, it is ensured that white carbon is uniformly added in the middle of polyurethane heat-insulation board core material after making finished product, solve polyurethane external wall insulation board
Comprcssive strength is weak, and fire resistance is low, and density is big to wait not enough, and sending out for polyurethane is added and then carried out before white carbon black raw material foamed solidification
Being blanched is shaped, and enormously simplify whole Making programme, and whole technological operation is convenient, can be entered in actual plant produced
One step popularization and application.
