Embodiment 4:
Carpet anti-flaming dope formula, the raw material type of described carpet anti-flaming dope comprises: latex, water, filler and thickener, described filler is made up of aluminium hydroxide and two kinds of fillers of APP, and latex, aluminium hydroxide and APP are that mass fraction is respectively: 100,38,14; Described latex is styrene-butadiene latex, and its solid content is 52%, its pH=7.2; Described aluminium hydroxide is the aluminium-hydroxide powder of particle diameter 7.1 μ m; Described APP is the APP powder of particle diameter 3.4 μ m; Described thickener is acrylic thickener, and its solid content is 20%.
The method that adopts formula in above-mentioned 4 embodiment to prepare carpet fire proofing is: in wide-mouth plastic tank, add successively latex, water, filler and thickener, rotating speed dispersion 12-16 minute with low-speed mixer with 800r/min, carpet anti-flaming dope solid content is controlled to 50%, and viscosity is for being controlled at 12000mPas.
In the present embodiment, the carpet anti-flaming dope of also being prepared by the formula adopting in above-mentioned four embodiment carries out contrast test, and test case is as follows:
1, paint viscosity: because exploitation speed and the material loading speed of coating machine are constant, thereby in coating process, stable paint viscosity is more conducive to obtain the coating of homogeneous. And the good coating of stability of viscidity, the operability in actual production process is good, uses continuously several days, and there is not any change in its rheological property. Experimental result shows that the paint viscosity that adopts the formula in embodiment 3 to prepare is the most stable over time, and embodiment 4 takes second place, the coating of embodiment 1 and embodiment 2 quite, stability is lower, but all reaches the standard of common carpet anti-flaming dope in prior art.
2, the bond strength of coating: as carpet paint used for coating, bond strength is the important indicator of weighing carpet performance. The results show, the dry bond strength of the coating that the formula in employing embodiment 3 makes is the highest, this is that filler due to the two kinds of different-grain diameters arrangement mode under this proportioning has obtained optimization, make after coating film forming, filler grain has formed accumulation mode the most closely in coating, the now contact area maximum of adhesive and filler grain, has obtained the coating of higher bond strength. In addition, owing to having formed the coating structure that filler grain densification is arranged, make coating have better iris action to the intrusion of moisture, be conducive to the lifting of the wet bond strength of coating.
3, fire resistance: fire proofing is divided into organic fire-retardant and inorganic combustion inhibitor. Organic fire-retardant (as halide-containing) flame retarding efficiency is high, but poor heat stability is toxic; Inorganic combustion inhibitor (as APP, aluminium hydroxide, magnesium hydroxide etc.) Heat stability is good, produces without pernicious gas, and security is good, can also reduce costs as packing material simultaneously. APP (APP) is the research field that current phosphorus flame retardant relatively enlivens, and its fire retardant mechanism is: at high temperature, APP can resolve into rapidly ammonia and polyphosphoric acid, the oxygen concentration of ammonia in can diluent air, thus play fire-retardant effect. In addition, APP is strong dehydrating agent, can make polymer dehydration carbonization form charcoal layer, prevents contacting of polymer and oxygen. Aluminium hydroxide flame-retardant mechanism is: after pyrolytic, produce water volatilization, to reduce environment temperature, play fire retardation. Based on the different fire retardant mechanisms of these two kinds of fire-retardant fillers, the present invention has studied APP and the fire protecting performance of aluminium hydroxide under different proportionings, and a kind of formula of the best is provided. The firing resistance of coating is assessed by test limits oxygen index (OI). Limited oxygen index refers to that polymer is in oxygen and nitrogen mixture body, and when the firm volume-fraction concentration that can support its oxygen, material carries out the required minimum oxygen concentration of flaming combustion in oxygen-nitrogen mixture stream when burning in. It is the index of exosyndrome material burning behavior, and limited oxygen index is higher represents that material is more nonflammable. Experimental result shows, adopts the limited oxygen index of the coating that the formula in 4 embodiment makes to approach 30%, substantially suitable with traditional halogen flame retardant.
To sum up, when carpet anti-flaming dope formula of the present invention adopts aluminium hydroxide and APP adapted, can obtain good cooperative effect. In the time that the proportioning of APP and aluminium hydroxide is 5:2, can make fire-retardant synergy maximize. Under this proportioning, the fire-retardant filler particle of two kinds of different-grain diameters can form best stacking arrangement mode in coating, has greatly improved the stability of viscidity of coating and the bond strength of coating simultaneously.
Below be only the preferred embodiment of the present invention, protection scope of the present invention is also not only confined to above-described embodiment, and all technical schemes belonging under thinking of the present invention all belong to protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
