Abstract
The invention provides a flame retardant paint containing magnesium hydroxide. The flame retardant paint is characterized in comprising a paint ingredient, magnesium hydroxide, antimony oxide, and zinc borate. According to the flame retardant, magnesium hydroxide fire retardant, antimony oxide fire retardant, and zinc borate fire retardant which possess high efficiency and excellent smoke suppression performance are added into the flame retardant paint, so that flame resistance of the flame retardant paint is increased effectively, flame resistance of furniture (especially wooden furniture, and furniture made of polymer materials) which is coated with the flame retardant paint is improved, and significant practical significance and a promising market prospect are achieved.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of flame retardancy paint.
Background technology
Paint is one of indispensable material in Household fit-up and decoration process.Present paint is on the market of a great variety, but these paint majorities just have protection, decoration function, and function ratio is more single.Along with the increase of people to paint functional requirement, existing paint can not meet people's needs, expects to have the paint of new function to occur.
Summary of the invention
The present invention aims to provide a kind of paint with flame retardancy.
Particularly, paint of the present invention is a kind of flame retardancy paint that contains magnesium hydroxide, it is characterized in that, comprises following component: paint ingredients, magnesium hydroxide, weisspiessglanz and zinc borate.
Wherein, the mass fraction of each component is preferably: paint ingredients 50-80 part, magnesium hydroxide 5-15 part, weisspiessglanz 5-10 part and zinc borate 8-15 part, more preferably: paint ingredients 60-75 part, magnesium hydroxide 8-12 part, weisspiessglanz 7-9 part and zinc borate 10-12 part, be particularly preferably: 11 parts of 70 parts of paint ingredientss, 10 parts of magnesium hydroxides, 8 parts of weisspiessglanzs and zinc borates.
Fire retardant claims again incombustible agent, flame-proofing agent or fireproofing agent, is a kind of for improving the special auxiliary chemicals of flammable inflammable material combustionproperty, is widely used in the fire-retardant processing of all kinds of finishing materials.Material after fire retardant processing, in the time being subject to extraneous burning things which may cause a fire disaster attack, can effectively stoping, delays or stop flame transmission, thereby reach fire-retardant effect.
Any burning is limited at shorter time institute's liberated heat, if can absorb a part of heat that burning things which may cause a fire disaster is emitted in the shorter time, flame temperature will reduce so, be radiated burning surface and act on the heat that the flammable molecule having gasified is cracked into free radical and will reduce, combustion reactions will obtain inhibition to a certain extent.Under hot conditions, there is strong thermo-negative reaction in fire retardant, absorbs the part heat that burning is emitted, and reduces the temperature on combustiblematerials surface, effectively suppresses the generation of inflammable gas, stops spreading of burning.
Fire retardant mainly comprises inorganic combustion inhibitor, halogenated flame retardant (organic chloride and organic bromide), phosphorus flame retardant (red phosphorus, phosphoric acid ester and halogenated phosphate etc.) and nitrogenated flame retardant etc.Because halogen flame discharges a large amount of cigarettes and toxic gas in the time burning, environment and human health are worked the mischief, therefore,, along with the raising of people to safety and environmental requirement, do not use or use less the halogen flames such as chloride, bromine to become inexorable trend.
The heatproof of inorganic combustion inhibitor can reach 1700 DEG C, smoke suppressing effect is good, at high temperature do not produce toxic gas, thereby in the time of burning, do not cause secondary pollution, but also there is the advantages such as cheap, wide material sources, nontoxic, corrosion-free, good stability, under this external normal temperature and high temperature, without any smell, after brushing, film does not affect the original color of object, and sticking power is good.Therefore, the use of inorganic combustion inhibitor is subject to people's favor.
The fire retardant mechanism of the metal hydroxides in inorganic combustion inhibitor is: when decomposes, discharge crystal water, this is a strong endothermic reaction, recept the caloric very large, can play the effect of cooling polymer, the water vapour that simultaneous reactions produces can dilute inflammable gas, suppress spreading of burning, thereby play fire-retardant effect.In addition, this based flame retardant can also adsorb soot dust granule, plays the cigarette effect that presses down.Flame retardant of magnesium hydroxide wherein has good flame retardant effect, and the amount of being fuming simultaneously can also reduce burning time, plays the effect of smoke suppressant, and Heat stability is good when safety non-toxic, high temperature process.
Flame retardant effect when weisspiessglanz, zinc borate use is separately not remarkable, in the time being used in conjunction with other fire retardant, can obviously improve flame retardant effect, therefore also has the title of fire retarding synergist or flame retardant.
The paint ingredients using in the present invention can adopt conventional on the market common paint, the general kind of fancy paint has phenolic paint, alkyd paint, pyroxylin(e)finish, urethane (PU polyester) paint, Polyester Paint, acrylic paint etc. at present, wherein polyurethane paint is that current upholstery uses extensively, one of paint kind that consumption is maximum.
The present invention by efficient, smoke-suppressing good, the flame retardant of magnesium hydroxide of nontoxic cheapness and weisspiessglanz, zinc borate flame retardant are applied in paint, effectively improve the flame resistivity of paint, thereby the flame resistivity that has improved the furniture (especially wood furniture, polymer materials furniture) that has used this paint, has very important realistic meaning and market outlook.
Embodiment
Describe the present invention in detail below in conjunction with embodiment; but the following examples are only preferably embodiment of the present invention; protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Embodiment 1
After the polyurethane paint of buying on market 50 mass parts, magnesium hydroxide 5 mass parts, weisspiessglanz 5 mass parts and zinc borate 10 mass parts are mixed, be painted on wood furniture.After dried coating film, carry out flame resistance test.Result shows, this paint has satisfied flame retardancy.
Embodiment 2
After the polyurethane paint of buying on market 70 mass parts, magnesium hydroxide 10 mass parts, weisspiessglanz 8 mass parts and zinc borate 11 mass parts are mixed, be painted on wood furniture.After dried coating film, carry out flame resistance test.Result shows, this paint has satisfied flame retardancy.
