Description
Technical field
The present invention relates to a kind of polyurethane sheet, relate in particular to a kind of environment-friendly anti-seepage fire-retardant heat insulation super-strong decorative sheet for external wall.Polyurethane plastics has purposes very widely, especially as heat insulating material, has obtained people's favor especially.At present existing many patents and document disclose the polyurethane plastics with various performances, reported a kind of base polyurethane prepolymer for use as that adds bromine class material and have fire resistance as Chinese patent CN1105676A, the part but the technology that this patent provided also comes with some shortcomings, its fire resistance is desirable not enough, oxygen index (OI) only is 26, can not satisfy the fire-retardant requirement of external-wall heat-insulation material.
Summary of the invention
The objective of the invention is to disclose a kind of environment-friendly anti-seepage fire-retardant heat insulation super-strong decorative sheet for external wall, to overcome the defective of prior art.The component and the parts by weight of the said environment-friendly anti-seepage fire-retardant heat insulation super-strong decorative sheet for external wall of the present invention comprise:
Blowing agent 20～40
Isocyanates 130～500
Polyethers 100～150
Crosslinking agent 10～15
Fire retardant 15～40
Stabilizing agent 3～5
Catalyzer 8～12
Preferably:
Blowing agent 30～35
Isocyanates 300～450
Polyethers 120～140
Crosslinking agent 10～13
Fire retardant 18～35
Stabilizing agent 3～4
Catalyzer 9～12
Be more preferably:
Blowing agent 30～32
Isocyanates 350～450
Polyethers 125～130
Crosslinking agent 10～12
Fire retardant 18～28
Stabilizing agent 3～4
Catalyzer 10～11
Said blowing agent is an anion surfactant, comprise sodium sulfate of polyethenoxy ether of fatty alcohol or (with) neopelex etc.; Said polyethers comprises pentaerythrite ether, ethylenediamine polyethers, glycerin polyether or polyalcohol polyether etc.; Said crosslinking agent is that the heteroaromatic polyethers is or/and phenol is little molecule crosslinked dose.Said fire retardant is the polyethers of chloride element, can adopt commercially available back-fire relief polyethers, as the back-fire relief polyethers of new photochemical factory in Shanghai and Suzhou, Jiangsu evolution plant produced; Stabilizing agent is a silicone oil; Said catalyzer comprises triethylamine, triethyl group hydramine, tin acetate, dichloro dibutyl tin etc.;
Each above-mentioned component is evenly mixed, in moulding press, adopt conventional method compression molding, be prepared into the required polyurethane plate that is used for exterior-wall heat insulation with fire resistance.Above-mentioned polyurethane has very excellent flame-retardant, adopts GB/T-2406.93 to carry out the test of fire resistance, and its result is as follows:
Oxygen index (OI): 34 ± 1.
By above-mentioned disclosed technical scheme as seen, because the present invention has adopted with isocyanates and has had the back-fire relief polyethers of reactivity worth preferably, and carry out structurally-modified to isocyanates, therefore, polyurethane function admirable of the present invention, especially fire resistance is more excellent, can be used for preparing the external-wall heat-insulation material with fire resistance.
Below will the present invention is further illustrated by embodiment.
