Abstract

The flame-retardant modified coating of antidetonation that the present invention announces, the coating is especially suitable for floor, the surface of door and window, the materials such as polyurethane are used due to no in raw material, the pernicious gases such as HCN and CO will not be produced in burning, it is a kind of environment-friendly coating, with adhesive force is strong, high mechanical strength, resistance to elevated temperatures are good, flame retardant effect is notable.

Description

The flame-retardant modified coating of antidetonation

Technical field

The present invention relates to a kind of flame-retardant modified coating of antidetonation.

Background technology

In general anti-flaming dope is applied to flammable substrates surface, to change material surface combustion characteristics, blocks fire Rapid sprawling；Or be applied on building element, to improve the sapecial coating of the fire endurance of component, claim fireproof coating.Fire prevention Coating is exactly by the way that on the surface of those combustible materials, paint brush can be improved into the refractory ability of material, slow down propagation of flame biography Speed is broadcast, or can prevent to burn within a certain period of time, this kind of coating is referred to as fireproof coating, or is called anti-flaming dope.Fire prevention applies The fire prevention principle of material can substantially be summarized as at following 5 points：Fireproof coating has flame retardancy or noninflammability in itself, makes to be protected base material Not direct and air contact, postpone the speed that object catches fire and reduces burning；Fireproof coating, which removes, itself has flame retardancy or non-ignitable Outside property, it also has relatively low thermal conductivity factor, can postpone flame temperature to by the transmission of protection base material；Heated point of fireproof coating Non-ignitable inert gas is solved, the heated imflammable gas decomposited of protected object body is watered down, is allowed to nonflammable or burning velocity Slow down；Nitrogenous fireproof coating is heated to decomposite the groups such as NO, NH3, with organic free radical chemical combination, interrupts chain reaction, reduces Temperature；Expanding fire-proof paint expanded by heating foams, and forms carbonaceous foam thermal insulation layer and closes protected object, delay heat with The transmission of base material, prevent object ignition or because temperature rise and caused by intensity decline；Intumscent Flame Retardant System is typically Refer to using phosphorus, nitrogen, carbon as the composite flame-retardant agent of main nucleus, it is usually what is be made up of three parts：Agent, charing Catalyst and swelling agent.When being heated with its fire-retardant polymer, certain thickness porous layer of charcoal, the layer of charcoal can be formed on its surface Function with heat-insulated, oxygen barrier, suppression cigarette and anti-molten drop, so as to play good fire retardation.At present, expansion type flame retardant is extensive Applied to the fire-retardant of the materials such as plastics, rubber, fiber, coating, timber.When fire proofing can delay the generation of fire due to it Between, and it is widely used in building field, particularly wood floors in building field, these combustible material surfaces of door and window.But often Anti-flaming dope, because it contains the materials such as polyurethane, the toxic gases such as HCN, CO can be produced in burning.In addition, also Poor adhesion be present, easily come off, the defects of service life is short, cost is high.

The content of the invention

The present invention is directed to aforementioned technical problem, designs a kind of flame-retardant modified coating of antidetonation, is matched according to mass ratio as follows：

10 ~ 15 parts of polyvinyl alcohol,

25 ~ 30 parts of Lauxite,

10 ~ 12 parts of graphite particle,

Aluminum oxide 0.5-5 parts,

10 ~ 14 parts of titanium dioxide,

Organosilicon levelling agent 0.5-2 parts,

5 ~ 10 parts of molybdenum oxide,

5 ~ 10 parts of dispersant,

8 ~ 16 parts of thickener,

Acrylic resin 15-25 parts,
