Description

Flame-retardant insulating paint and preparation method thereof

Technical field

The present invention relates to a kind of coating and preparation method thereof, particularly relate to a kind of flame-retardant insulating paint of installing on buildings or the storage tank and preparation method thereof that is coated with.

Background technology

Along with the global environment temperature continues the exhausted day by day of the rising and the energy, the heat-insulating energy-saving paint of health environment-friendly more and more receives people's favor.Simultaneously, modern architecture material or other industry have also proposed very high requirement to the flame retardant properties of coating, and therefore, exploitation has heat insulation simultaneously and coating anti-flaming function has very important significance.Simultaneously, how to control coating composition with heat insulating function and have the ratio of the coating composition of flame retardant properties, making the heat insulation and flame retardant properties of coating reach best effect simultaneously also becomes the technical barrier that needs to be resolved hurrily.

Summary of the invention

The present invention is intended to propose a kind of coating that has the anti-flaming thermal-insulation performance simultaneously, and this coating comprises following component by weight percentage: 50% fluorocarbon resin solution, 1% fumed silica; The Rutile type Titanium Dioxide of 5%-17%, the Antimony Trioxide: 99.5Min of 9%-19%, the white lake of 6%-10%; The Marinco H of 4%-9%, 0.3% skimmer, 0.2% flow agent; The cenosphere of 8%-20%, 4.5% N-BUTYL ACETATE.

The solvent of said fluorocarbon resin solution is preferably a kind of or its mixture in YLENE, the N-BUTYL ACETATE.

The mass content of fluorocarbon resin is preferably 50%-70% in the said fluorocarbon resin solution.

Fluorocarbon resin has good outside durabitity, and anti-ultraviolet property is good, and paint film can reach 15-20 working life.

To make the paint film tool be that the light of 380-2500 nanometer has the reflex action up to 90% to wavelength through grinding the levigated Rutile type Titanium Dioxide, can make the temperature of body surface reduce 8-15 ℃ in summer.The thermal conductivity of cenosphere is low, reduces thermal conduction, can stop the transmission of the inside and outside heat of object.

Antimony Trioxide: 99.5Min makes the paint film tool when running into flame, generate the halogen thing, forms fine and close film and covers body surface.White lake, Marinco H decompose generation water, reduce the body surface temperature, stop burning.The three is used better effects if.

For flame retardant properties and the heat-proof quality that makes coating of the present invention reaches best effect simultaneously, the contriver finds through repeatedly studying and test the back, and is heat insulation following with all good coating proportioning components of flame retardant effect:

50% fluorocarbon resin solution, 1% fumed silica, 13% rutile titanium white powder, 9% Antimony Trioxide: 99.5Min, 6% white lake, 4% Marinco H, 0.3% skimmer, 0.2% flow agent, 12% cenosphere, 4.5% N-BUTYL ACETATE.After using this coating, the coating fire-protection rating reaches the B1 level, and the heat reflectivity of sunshine can make the temperature of body surface reduce 8-15 ℃ in summer up to more than 80%, can make room temp reduce 3-11 ℃.The thermal conductivity of coating is little, effectively stops thermal conduction, and its energy-saving effect can reach 10-50% according to the difference of envrionment temperature, space size.

The production technique of above-mentioned coating is following: get all the each composition raw material ready according to above-mentioned weight proportion; At first fluorocarbon resin solution is added in the stirred pot, add fumed silica, white titanium pigment, Antimony Trioxide: 99.5Min, white lake, Marinco H, skimmer then while stirring, high speed dispersion 20-30 minute; And then adding flow agent and part N-BUTYL ACETATE; Once all be added in before the sand mill grinding because the needs of coating complete processing, the N-BUTYL ACETATE in the prescription are suitable, only add earlier the half the of formula ratio usually; Second half adds after sand mill grinds again, stirs.With below the sand mill mesh-of-grind to 10 micron, add cenosphere and residue N-BUTYL ACETATE, stir, filter and promptly can be made into above-mentioned coating.

Add 7% solidifying agent during use and stir, add spray behind an amount of N-BUTYL ACETATE, brush, roller coating, got final product in dry 24 hours to coated article spare surface.

The above-mentioned heat-insulating flame-retardant coating that the present invention proposes can have the performance of heat-insulating flame-retardant simultaneously concurrently, and compares with other coating according to the coating that the proportioning that the present invention proposes is processed, and fire-retardant and heat insulation performance is equilibrium more, can realize better anti-flaming thermal-insulation effect.

Embodiment

Describe embodiments of the invention below in detail; It is obvious that; Described embodiment is a part of embodiment of the present invention but not all; Based on the embodiment among the present invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that is obtained under the creative work prerequisite.

The coating of one embodiment of the present of invention proportioning components by weight percentage is following: 50% fluorocarbon resin solution, 1% fumed silica, the Rutile type Titanium Dioxide of 5%-17%; The Antimony Trioxide: 99.5Min of 9%-19%, the white lake of 6%-10%, the Marinco H of 4%-9%; 0.3% skimmer, 0.2% flow agent, the cenosphere of 8%-20%; 4.5% N-BUTYL ACETATE, wherein, the mass content of fluorocarbon resin is 70% in this fluorocarbon resin solution.

For flame retardant properties and the heat-proof quality that makes coating of the present invention reaches best effect simultaneously, the contriver has carried out repeatedly studying and testing, and enumerates out following four representative embodiment at present, and the proportioning components of these four embodiment coating is seen table one.

Table one: the proportioning components contrast (weight percent) of four embodiment coating

Composition	Embodiment one	Embodiment two	Embodiment three	Embodiment four
					Fluorocarbon resin solution	50	50	50	50
Fumed silica	1	1	1	1
					Rutile type Titanium Dioxide	15	17	5	13
Antimony Trioxide: 99.5Min	15	0	19	9
