Problems solved by technology

Chinese patents CN1434063A, CN136U86A disclose a kind of heat reflective paint respectively, they all have adopted polymer emulsion as film former, and hollow microsphere is heat-insulating material, adds pigment, filler, auxiliary agent etc. to form again, and CN1434063A discloses Heat reflective heat insulation coating is based on epoxy modified acrylic emulsion, which has good corrosion resistance and heat insulation function, but the outdoor weather resistance and stain resistance of this product are not ideal. The highest reflectivity is only 80%, most of the cases are between 50% and 80%
The reflective and heat-insulating coating disclosed by CN136U86A is based on acrylic nanoemulsion as a film-forming material, and an infrared reflector is added, which has a certain heat-light reflection and heat-insulation effect. The disadvantage of this coating is that too many fillers are added, and the heat-light reflection functional pigments are less , affecting its solar reflectance

Embodiment 1

[0032]First, 100 kg of fluorocarbon resin, 30 kg of acrylic resin, 40 kg of rutile titanium dioxide, 20 kg of silicon dioxide, 0.5 kg of dispersant BYK-116, 0.5 kg of leveling agent BYK-358N, and 0.4 kg of defoamer BYK-141 , Anti-sedimentation agent BYK-410 0.6 kg is uniformly mixed in a high-speed disperser, the speed is 1000-1400 rpm, and the time is 15 minutes; the mixed material is ground three times by a sand mill, and the time for each time is about 1 hour. When the fineness reaches below 25 microns, it can be used as a semi-finished product; then add the measured hollow microspheres to the semi-finished product, and then stir for 20 minutes at a speed of 600-800 rpm, and finally the finished thermosetting reflective heat insulation can be obtained coating. When used, the weight ratio is: thermosetting reflective heat-insulating coating: curing agent = 100:10; add biuret, stir well, and use after 30 minutes of curing.

Abstract

The invention discloses a thermosetting reflection thermal insulation coating. The thermosetting reflection thermal insulation coating is characterized by being prepared from the following components in part by weight: 100 to 150 parts of thermosetting fluorocarbon resin, 30 to 40 parts of thermosetting acrylic resin, 10 to 20 parts of cenosphere, 40 to 60 parts of titanium dioxide, 20 to 30 parts of silicon dioxide, 30 to 40 parts of aid, and 20 to 30 parts of curing agent; and the thermosetting reflection thermal insulation coating has the characteristics of high chemical resistance, high temperature resistance, weather resistance, and stain resistance, good self-cleaning property, long service life of a coating and the like. Moreover, the appearance of a building can be beautified and decorated by color mixing, and the effects of reflection and thermal insulation can be fully exerted.

Description

technical field [0001] The invention relates to a preparation method of a building reflective heat-insulating paint, in particular to a thermosetting reflective heat-insulating paint and a preparation method thereof, belonging to the technical field of chemical compositions. Background technique [0002] my country is a country with a shortage of per capita resources, and energy shortage is the main contradiction restricting my country's economic development. In July 1996, J6J26-95 "Energy Conservation Standards for Civil Buildings (Heating Residential Buildings)" was promulgated and implemented. The "Standard" is based on the energy consumption of residential buildings in the 1980s in my country, and requires new residential buildings to save 50% of heating energy consumption, of which 30% is achieved by improving the thermal insulation performance of building envelopes, and the other 20% is achieved by improving heating. The efficiency of the boiler and the outdoor heating...
