Abstract
The present invention relates to non-toxic fire-resistant adhesive. Mainly, a fire-resistant composition is added in adhesive base material. The fire-resistant composition is composed of expansion graphite, a carbon layer forming agent and a carbon layer catalyst. When the non-toxic fire-resistant adhesive is heated or burned, the heated surfaces of the carbon layer forming agent and the adhesive base material are dehydrated to form a carbon casing layer, so that the graphite which is heated to expand to grow into a worm shape is tightly fixed on the carbon casing layer. The dual effect of thermal insulation and fire resistance, which is formed by the firm carbon casing layer and the fixed wormlike graphite, can effectively prevent fire and combustion and achieve the effects of innocuity, little smoke, no drop and difficult combustion.
Description
Technical field
The invention relates to a kind of caking agent, refer to a kind of difficult combustion caking agent especially, have nontoxic, low cigarette, do not drip vertical advantage.
Background technology
Recently, owing to the attention of people for the house lives and properties, also ardent day by day to the fp requirement, the material selection of daily living article all develops towards difficult burning gradually.And general daily living article all uses caking agent unavoidably, for example is used in carpet, wallpaper, automobile inside ... or the like the aspect.Based on fire prevention, difficult combustion reason, if only use incombustibe material matter on general material, but caking agent base material (Base) therebetween itself still is flammable, and then integral body still can't reach hundred-percent difficult combustion effect.
Caking agent was made difficult burning in the past, and all be added into the compound (for example organic chloride or bromide) of halogen series traditionally in its base material, the inorganic powder of collocation part again (for example weisspiessglanz) reaches the effect of difficult combustion.Yet, can make caking agent reach the effect of difficult combustion though be added into the incombustible agent of halogen series, but when high temperature or chance flame, the amount of being fuming is very big, the gas that is produced also has toxicity, and easy of caking agent is vertical, will directly damage personnel in the scene of fire, indirectly environment is polluted, very easily cause spreading and the expansion of disaster of fire.Based on safety, environmental requirement, many countries and regions have all limited and have used halogen series incombustible agent.
The contriver whence originally in the spirit of positive invention, is urgently thought a kind of " nontoxic difficult combustion caking agent " that can address the above problem because of in this, and several times research experiment is eventually to the invention of finishing this Jiahui common people.
Summary of the invention
The objective of the invention is is providing a kind of nontoxic difficult combustion caking agent, can reach nontoxic, low cigarette, not drip vertically, and has the effect of difficult combustion.
