Abstract

A kind of fire resistant lacquer is main base-material with inorganic silicate, and each composition weight proportion is: inorganic silicate 30～80, clay 4～19, asbestos 2～11, inorganic filler 13～60, swelling agent 1～15, blender 2～10, silicon sol 10～60 also can add siccative 1～15 in addition.This lacquer can be widely used in the lacquer system of various items such as woodenware, house and plastics such as furniture.Fire resistance is strong, fast drying, and manufacturing process is simple, less energy consumption, cost is low, less investment, equipment is simple, and cheap raw is wide.

Description

Flame retardant paint

The invention belongs to speciality coating, is the flame retardant paint with resistance to elevated temperatures.Existing paint substantially all is organic coating, be used for brushing and reach decoration function as protective cover at article surfaces such as woodenware, but owing to all be with drying grease or resin as base-material, the former capital not only can not prevent fires, and also has combustion-supporting effect, can't tackle fire failure.New technology has been invented out some and has been used for antirust or the fp speciality coating is applied to industrial; protect outward especially for metal and (to see Japan special permission 46～34790～1; United States Patent (USP) 3317455; United States Patent (USP) 3380941); but all be with the silicone resin be base-material again with other high-temperature resisting pigments and the formulated organosilicon coating of filler; because the silicone resin high-temperature behavior is not good enough; especially make and require height; difficulty is big; the raw material costliness; the cost height is not suitable for being used to objects such as common furniture of the system of coating with lacquer and house woodenware.

Purpose of the present invention is exactly in order to overcome the defective of above-mentioned prior art, to provide a kind of high-temperature behavior better, can being widely used in the flame retardant paint of object lacquer systems such as common wealth furniture and house woodenware, and is good and cheap.

The solution of the present invention is: base-material is based on inorganic silicate, the shared part by weight of each composition was during whole prescription was formed: inorganic silicate (water glass, potassium silicate, Calucium Silicate powder, Magnesium Silicate q-agent, a kind of or wherein multiple mixing in the lithium silicate) 30～80, clay (kaolin) 4～19, asbestos 2～11, inorganic filler (can be a perlite, mica, one or more mixing in the silica) 13～60, swelling agent (dinitrobenzene five, first justice tetramine, a kind of or many person of phenol formaldehyde (PF) mixes) 1～15, blender (can be a carboxymethyl cellulose, starch, a kind of in the dextrin, also can be multiple mixing) 2～10, silicon sol 10～60.

The present invention is in order to make its fast drying, also can add a certain amount of siccative, they are: silicide or muriate, for example one or more among calcium chloride, zinc chloride, the silicofluoride etc. mix all can, its add-on can be to add 1～15 on the invention described above prescription basis.

Manufacture craft flow process of the present invention is basic identical with general system lacquer craftwork.After each solid material is pulverized, cross 325 mesh sieves, formulated with base-material then.Using method is identical with general paint, can brush, and also can spray.Can be coated in timber device, fiberboard, cement plate, concrete member, as protecting materials, light not only attractive in appearance, and can block burning is avoided and is reduced fire losses on part metals and the plastics.Be coated with the timber of frie retardant coating of the present invention or other material device when running into high temperature (when mainly referring to the thermal-flame because of the generation of catching fire), this coating (paint film) will expand (can be expanded to 2～5 mm thick) by 1 mm thick, thereby form closely and thick fireproof thermal-insulation layer, stop by lacquer thing and flame catalytic combustion.

Effect of the present invention and the advantage that is relatively had with existing general paint: (1) has excellent fireproof performance.(2) time of drying is fast.(3) raw material is inexpensive, and wide material sources, cost are low.(4) manufacturing process is simple, and facility investment is few, and energy consumption is low.(5) easy to use, period of storage is long.

Embodiment. form by weight a part prescription: water glass 50, clay 10, asbestos 8, perlite 30, phenol formaldehyde (PF) 3, carboxymethyl cellulose 7, silicon sol 30, calcium chloride 4.Test product after the modulation is brushed on dry China fir plate, and 0.5～1 millimeter of thickness is placed on after doing on the ironmaking coke oven flame that calcination is about 20 minutes under 500～700 ℃ of temperature, and paint film does not break, and does not melt, no poison gas, and plank does not burn.

Claims (2)

1, a kind of flame retardant paint, the components by weight percent that the invention is characterized in each composition in its prescription is: inorganic silicate (water glass, potassium silicate, Calucium Silicate powder, Magnesium Silicate q-agent, one or more mixing in the lithium silicate) 30～80, clay (kaolin) 4～19, asbestos 2～11, inorganic filler 0 perlite, mica, one or more mixing in the silica) 13～60, swelling agent (dinitrobenzene five, first justice tetramine, any one or multiple mixing in the phenol formaldehyde (PF)) 1～15, blender (carboxymethyl cellulose, starch, any one or multiple mixing in the dextrin) 2～10, silicon sol 10～60.

2, flame retardant paint according to claim 1 is characterized in that: add silicide, muriate, (one or more mixing in calcium chloride, zinc chloride, the silicofluoride) 1～15 in the described recipe ingredient in addition.
