Description
Technical field
The present invention relates to anti-flaming dope technical field, in particular to the fire-retardant back gluing and its production work of a kind of no smoke toxicity
Skill.
Background technique
Fire-retardant back gluing is exactly by that on the surface of combustible material, can improve the refractory ability of material, slow down paint brush
Propagation of flame spread speed, or can prevent to burn within a certain period of time, also referred to as fireproof coating.Fireproof coating is for combustibility
Substrate surface can be reduced by the rapid sprawling of the combustibility of painting material surface, retardance fire, to improve by painting material fire resisting pole
A kind of sapecial coating of limit.
With the development of China's synthetic material industry and the continuous expansion of application field, fireproof coating is in chemical building material, electricity
It is had a vast market in the every field such as sub- electric appliance, communications and transportation, space flight and aviation, household furniture, interior decoration, clothing, food, lodging and transportion -- basic necessities of life
Prospect.In addition, the fields such as coalfield, oil field, forest extinguishing also promote, China is fire-retardant, extinguishing chemical production is faster develops.China
Fireproof coating has evolved into the second macromolecular material modified additive for being only second to plasticizer.Although current fireproof agent is big
The application of amount ground, but the fire protecting performance of current fireproof agent is more general, is not able to satisfy people to the high request of flameproof effect.And
Traditional fireproof coating is usually halogenated flame retardant, but halogenated flame retardant burning when can generate toxic irritative gas and
It is also easy to produce secondary pollution as waste.To meet increasingly strict environmental requirement, urgent need finds one kind and has both flame retardant property
With the anti-flaming dope of environmental-protecting performance.
104487532 A of CN discloses flame retardancy carpet back coating layer, it includes following components: a) 20 to 70 weight %
The one or more polyolefin-waxes formed by one or more C3-C18- alpha-olefins and optional ethylene, b) 9 to 30 weight %
Expanded graphite, c) 5 to 30 weight % other fire retardants, d) 0 to 15 weight % the auxiliary agent with antistatic property, e) 0
To one or more amorphous, atactic poly- α-alkene of one or more resins of 12 weight %, f), 0 to 40 weight %
Hydrocarbon (APAO).
109694602 A of CN discloses a kind of fireproof flame-retardant coating, the group of the weight percent of the fire-proof flame-retarded agent
It is divided into water 55%-70%, ammonium polyphosphate 10%-15%, ammonium chloride 10%-15%, dispersing agent 5%-6%, catalyst 4%-
6%, defoaming agent 1%-3%.The fire-proof flame-retarded agent has the function of outstanding fire protection flame retarding, makes the object for coating the fire-proof flame-retarded agent
Also there is fireproof flame-retardant effect, greatly reduce the generation of fire, protect the safety of people.
Above-mentioned patent all has the effect of fire protection flame retarding, still, the fire-retardant principle of above-mentioned patent be by anti-flaming dope from
Body is difficult to burn or volume expansion is formed expansion heat insulation layer delays or inhibits the burning of polymer, with by flame-retardant polymer it
Between do not occur or seldom occur chemical action, but the flame retarding efficiency that the effect generates is not high, and can also generate and a little have
Evil gas.
Summary of the invention
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of good flame retardation effect,
Security performance is high, preparation process simply fire-retardant back gluing and its production technology without smoke toxicity.
The present invention to achieve the above object the technical solution adopted is that: a kind of fire-retardant back gluing of no smoke toxicity, the resistance
Combustion back gluing by being prepared following weight percentage components:
Foaming agent: 3-5%；
Crosslinking agent: 15-22%；
Expansible graphite: 15-20%；
Fire retardant: 5-8%；

Further, the foaming agent is one or both of sulfonate sodium or stearic acid salt compound.
Further, the crosslinking agent is silicone modified waterborne polyurethane dispersion liquid.
Further, the fire retardant is bridging property phosphorus flame retardant.
Further, the levelling agent is water-soluble high-molecular compound.
Further, the thickener is modified starch.
Further, the specific weight percent of the fire-retardant back gluing component are as follows:
Foaming agent: 3%；
Crosslinking agent: 15%；
Expansible graphite: 15%；
Fire retardant: 5%；
Levelling agent: 2%；
Thickener: 1%；
Water: 59%.
Further, the specific weight percent of the fire-retardant back gluing component are as follows:
Foaming agent: 5%；
Crosslinking agent: 22%；
Expansible graphite: 20%；
Fire retardant: 8%；
Levelling agent: 3%；
Thickener: 2%；
Water: 40%.
Further, the specific weight percent of the fire-retardant back gluing component are as follows:
Foaming agent: 4%；
Crosslinking agent: 20%；
Expansible graphite: 17%；
Fire retardant: 7%；

Thickener: 1.5%；
Water: 48%.
The invention also includes a kind of techniques of fire-retardant back gluing for preparing no smoke toxicity, which is characterized in that including following step
It is rapid:
(1), it weighs: according to requiring to examine various raw materials, being weighed according to formula rate spare after various raw materials；
(2), foaming agent, crosslinking agent, expansible graphite are sequentially added in agitator tank, is stirred evenly；
(3), fire retardant is added under stirring conditions, levelling agent stirs evenly；
(4), thickener, water under agitation, are sequentially added, uniform fire-retardant back gluing is stirred into.
A kind of fire-retardant back gluing of no smoke toxicity of the present invention and its beneficial effect of production technology are:
(1) expansible graphite (EG) is obtained after chemical oxidization method or electrochemical oxidation process processing by natural flake graphite
A kind of compound between graphite layers, for structure, EG is a kind of nanocomposite.Common H2SO4 aoxidizes EG obtained
When by 200 DEG C or more high temperature, redox reaction occurs between sulfuric acid and graphite carbon atom, generates a large amount of SO2, CO2
And vapor, make EG start to expand, and reach maximum volume at 1100 DEG C, 280 when final volume can achieve initial
Times.This characteristic enables EG to increase by the moment of volume by fray-out of flame when fire occurs.
(2) it is of the invention it is fire-retardant belong to solidifying phase fire retardant mechanism, it be by delay or interrupt solid matter generate it is flammable
Property substance and reach fire-retardant, be heated to a certain extent, expansible graphite will start to expand, thus formed one it is very thick more
Hole carburization zone, the carburization zone have enough thermal stability that fire-retardant main body and heat source are separated, to delay and terminate polymer
It decomposes, and itself is nontoxic, does not generate toxic and corrosive gas when heated, and smoke amount can be substantially reduced.
(3) EG is the key that improve flame retardant property, and the content of expansible graphite is less than 15%-20%, and flame retardant property is not up to
To the requirement of fire proofing, EG and fire retardant in the present invention can play its synergistic effect, keep flame retardant effect more preferable.Foaming agent mistake
More, the adhesive fastness of fire-retardant back gluing is bad, and blowing ratio is too low, and fire-retardant back gluing can penetrate into the front of fabric, influences beauty,
Therefore the foaming agent of 3-5% is optimal dose.
(4) fire retardant also adds the fire-retardant of crosslinking agent by the film forming with cross-linking agents without influencing crosslinking agent
Property and expansible graphite formation cooperatively form gas-liquid-solid phase flame-retardant system.Make crosslinking agent in burning without smoke toxicity and dropping,
It is carbonized together with fibrous material simultaneously.
Fire-retardant back gluing good flame retardation effect of the invention, security performance is high, and preparation process is simple, and economic and environment-friendly smokeless
Poison gas generates.
