Problems solved by technology

Radiant heat insulation coatings can radiate absorbed heat out of the room in the form of thermal emission, thereby adjusting the indoor temperature. However, the selection of functional pigments and fillers for preparing radiant heat insulation coatings and the sintering process are complicated, and it is difficult to achieve a stable emissivity.

preparation example Construction

[0030] A method for preparing the above-mentioned water-based thermal insulation coating, characterized in that: the steps are as follows:

[0031] (1) Add the dispersant sodium polyphosphate and antifreeze ethylene glycol into the distilled water according to the above ratio, place them on a low-speed mixer and stir well, and slowly add the composite phase change material and titanium dioxide in the order of density first and then large , stirring at a speed of about 3000 rpm, while adding the defoamer tributyl phosphate, then slowly adding the film-forming aid benzyl alcohol and 1 / 2 the thickener hydroxyethyl cellulose, stirring at a low speed and then moving to a high speed Mixer, add the remaining 1 / 2 thickener hydroxyethyl cellulose, stir at a speed of 3000 rpm, and stir for about 30-60 minutes to obtain the pigment paste;

[0032] (2) Slowly add 3M hollow glass microspheres, and stir at a low speed of 600 rpm for 30 minutes;

[0033] (3) Slowly add the film-forming subs...

Embodiment 1

[0050]The content of styrene-acrylic emulsion is 35%, coalescent 2%, antifreeze 2%, thickener 1%, defoamer 0.7%, dispersant 0.5%, 3M hollow glass microspheres 5%, paraffin / modified silicon The mass fraction of algae earth composite phase change material accounts for 15% of the total mass of the coating (the paraffin content in the composite phase change material is 40%), titanium dioxide 16%, and distilled water make up the balance.

[0051] Add the dispersant and antifreeze to distilled water, place it on a low-speed mixer and stir well, add the composite phase change material and titanium dioxide slowly in the order of density first and then increase, and stir at a speed of about 3000 rpm. Foaming agent, then slowly add film-forming aids and 1 / 2 thickener, stir evenly at low speed, then move to high-speed mixer, add the remaining 1 / 2 thickener, stir at 3000 rpm, stir for about 30 Minutes is the pigment paste.

Abstract

The invention relates to a water-based thermal insulation coating and a preparation method thereof. Titanium dioxide is mixed. The paint prepared by the invention is coated on the surface of the wall body, cured at normal temperature, and after being completely dried, it can play the role of heat preservation and heat insulation to regulate the indoor temperature of the building.

Description

technical field [0001] The invention relates to a thermal insulation coating used for interior and exterior walls of buildings, in particular to a water-based thermal insulation coating and a preparation method thereof, belonging to the technical field of chemical coatings. Background technique [0002] With the international community's increasing requirements for energy saving and emission reduction, wall insulation has become an important part of building energy conservation. At present, my country's thermal insulation materials are changing from industrial thermal insulation to architectural thermal insulation. Thermal coating is one of the development directions of building thermal insulation materials. Building thermal insulation coatings are often divided into three categories: barrier thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. The barrier heat insulation coating is a silicate composite coating based ...
