Abstract
The invention relates to an environment-friendly water-based nano-grade titanium dioxide thermal insulation paint and a preparation method thereof. The thermal insulation paint is prepared by stirring the following raw materials, by weight: 25-40 parts of resin synthetic emulsion, 30-40 parts of powders, 3-5 parts of auxiliary agents, 1-2 parts of a thickening agent, and 20-30 parts of water. The powders include nano-grade titanium dioxide powder. Compared with prior arts, a coating formed by the thermal insulation paint is much thinner than that of existing thermal insulation products, and is safer and more environment-friendly than existing products. With the paint, construction cost can be reduced, construction duration can be shortened, and fire is prevented.
Description
Technical field
The present invention relates to the preparation of a kind of coating, especially relate to a kind of environment-friendly aqueous nanometer titanium white heat insulating coatings and preparation method thereof.
Background technology
Chinese patent CN103555097A discloses a kind of insulating moulding coating and preparation method thereof, and its component is in weight fraction, with 45-60 part acrylic copolymer, 10-16 part nanometer titanium dioxide, 5-10 part nano silicon, 13-21 part glass microballoon；Insulating moulding coating is by preparing with step once: 10-16 part nanometer titanium dioxide and 5-10 part nano silicon are put into grinder and ground 15 minutes by (1)；(2) add the nanometer titanium dioxide after 45-60 part acrylic copolymer, 13-21 part glass microballoon, grinding and nano silicon in the mixing container, be sufficiently stirred for 15 minutes and be incubated 30-50 DEG C；(3) room temperature is cooled to room temperature, namely prepares required insulating moulding coating.Above-mentioned coating effectively completely cuts off infrared ray radiation and reduces building energy consumption, adopts glass microballoon to reduce the further trap heat of visible radiation, reduces carbon emission.But the safety and environmental protection performance of above-mentioned coating is poor.Insulating moulding coating is to waterproof, fire protecting performance, and especially the requirement of security performance is higher.Therefore, the environment-friendly aqueous nanometer titanium white heat insulating coatings of environmental protection thinner, safer becomes a kind of new demand.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide that one is thinner, environment-friendly aqueous nanometer titanium white heat insulating coatings and preparation method thereof more easily of constructing.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of environment-friendly aqueous nanometer titanium white heat insulating coatings, is formed by the raw material stirring of following components and weight portion:
Described powder body includes nanometer titanium dioxide.
Described resins synthesis emulsion is acrylic acid pure-acrylic emulsion.
Described acrylic acid pure-acrylic emulsion particle diameter is at 0.1-0.2 micron, and viscosity is at 300～1500Pa s, and testing conditions is 3#.60rpm.25 DEG C.
Described powder body also includes barium sulfate and triple superphosphate, and wherein, the weight ratio of nanometer titanium dioxide, barium sulfate and triple superphosphate is (10-20): (8-10): (8-20).
Described auxiliary agent includes following components and weight portion:
Described antibacterial is isothiazolone, and defoamer is mineral oil, and coalescents is Lauryl Alcohol ester, and dispersant is ammonium salt class dispersant.
Described thickening agent is association type alkali swollen thickener.
A kind of preparation method of environment-friendly aqueous nanometer titanium white heat insulating coatings, the method comprises the following steps:
(1) first all being put in stirred tank by water by recipe requirements, 300-600 rev/min is stirred；
(2) it is kept stirring for and puts into successively antibacterial, dispersant, propylene glycol, defoamer, nertralizer amp-95, stir, be sequentially added into and will not make to be neutralized reaction between auxiliary agent, slacken the function of auxiliary agent；
(3) to be mixed uniformly after powder body is added in stirred tank, speed being transferred to 1200-1600 rev/min, carries out the stirring of 45-60 minute, the addition order of powder body is undertaken by following principle: first add oil absorption few, add oil absorption bigger, first add powder body light add again powder body weight；
(4) when, after high speed dispersion, being down to low speed 500-600 rev/min, resins synthesis emulsion is all added in stirred tank；
(5) emulsion is stirring evenly and then adding into cellulose and coalescents；
(6) slowly stirring addition thickening agent is transferred to required viscosity again.
Environment-friendly aqueous nanometer titanium white heat insulating coatings is primarily directed to a product of insulation exploitation, and owing to insulated fire class requirement is higher, material therefor just has certain thickness, and operating expenses is high especially simultaneously.Environment-friendly aqueous nanometer titanium white heat insulating coatings be with exterior coating same thickness within 200 microns, there is extraordinary heat-insulation and heat-preservation function, simultaneously there is again weather-proof function.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1) the environment-friendly aqueous nanometer titanium white heat insulating coatings of the present invention is used generally to brush twice, the thickness of brushing is at 100 microns every time, therefore, use the environment-friendly aqueous nanometer titanium white heat insulating coatings integral thickness of the present invention at 200 microns, and the brushing thickness of existing thermal insulation coatings is general all at more than 3CM, therefore, the environment-friendly aqueous nanometer titanium white heat insulating coatings integral thickness using the present invention is thinner than existing insulating product a lot；
(2) the safer more environmental protection than existing product, it is thinner than insulation material, drops and will not cause safety problem in work progress, and in existing insulation material, dropped potential safety hazard in work progress；
(3) can reducing construction cost, the reduction of erection time: working procedure can reduce in work progress, on the basis of putty, priming roller coating 2 times again is just passable.And existing insulation for example, rock wool first to be cooked shelf, do rock wool, linked network, plaster and make putty again, then just priming does the coating of routine；
(4) product does not result in fire due to very thin.
