Embodiment 1

[0025] 1. Preparation of PVDF varnish

[0026] Weigh each component (parts by weight) according to the following formula: 30 parts of polyvinylidene fluoride, 10 parts of polymethyl methacrylate, 7.5 parts of propylene glycol methyl ether acetate, 17.5 parts of isophorone, 25 parts of titanium dioxide, 10 parts xylene.

[0027] Prepare PVDF varnish as follows:

[0028] (1) Add isophorone into a container with an ice-water bath, stir at a speed of 1500-1700rpm, and at the same time add polyvinylidene fluoride at a uniform speed at a speed of about 50-60g / min; add polyvinylidene fluoride After the completion, stop stirring, let stand for 20 minutes, start again and stir at 2500-2700rpm for 40 minutes to obtain PVDF resin dispersion;

[0029] (2) Pre-disperse polymethyl methacrylate, titanium dioxide, xylene, and propylene glycol methyl ether acetate evenly with a high-speed disperser to obtain a paint paste;

[0030] (3) Mix the dispersed PVDF resin dispersion liquid and pain...

Embodiment 2

[0035] This example is basically the same as Example 1, the difference is that when preparing heat-insulating and energy-saving fluorocarbon coatings, the components (parts by weight) are weighed according to the following formula: 45 parts of PVDF varnish, 30 parts of pigments and fillers, 24 parts of isophorone, 1 part of dispersant silane coupling agent (KH570). Among them, the pigment and filler are mixed with nano-scale ATO (radiation type), hollow glass microspheres (reflection type), and closed-cell perlite (barrier type) according to the mass ratio of 2:12:16.

Embodiment 3

[0037] 1. Preparation of PVDF varnish

[0038]Weigh each component (parts by weight) according to the following formula: 35 parts of polyvinylidene fluoride, 10 parts of polymethyl methacrylate, 10 parts of propylene glycol methyl ether acetate, 15 parts of isophorone, 15 parts of titanium dioxide, 15 parts xylene.

[0039] Prepare PVDF varnish as follows:

[0040] (1) Add isophorone into a container with an ice-water bath, stir at a speed of 1500-1700rpm, and at the same time add polyvinylidene fluoride at a uniform speed at a speed of about 50-60g / min; add polyvinylidene fluoride After the completion, stop stirring, let stand for 20 minutes, start again and stir at 2500-2700rpm for 40 minutes to obtain PVDF resin dispersion;

[0041] (2) Pre-disperse polymethyl methacrylate, titanium dioxide, xylene, and propylene glycol methyl ether acetate evenly with a high-speed disperser to obtain a paint paste;

[0042] (3) Mix the dispersed PVDF resin dispersion liquid and paint ba...

Abstract

The invention provides a PVDF varnish, heat-insulation energy-saving fluorocarbon paint, and preparation methods thereof. The PVDF varnish comprises the components of, by weight, 30-40 parts of polyvinylidene fluoride (PVDF), 10-15 parts of polymethyl methacrylate, 7-15 parts of methoxy propyl acetate, 15-25 parts of isophorone, 15-25 parts of titanium dioxide, and 10-20 parts of xylene. The heat-insulation energy-saving fluorocarbon paint comprises the components of, by weight, 30-50 parts of PVDF, 25-40 parts of pigment and filler, 20-30 parts of isophorone, and 0.5-1 part of a dispersing agent. The invention provides the high-performance heat-insulation fluorocarbon paint with polyvinylidene fluoride (PVDF varnish) as a substrate and with a comprehensive heat insulation effect.

Description

technical field [0001] The invention relates to the field of building heat-insulating coatings, in particular to a heat-insulating and energy-saving fluorocarbon coating and a preparation method thereof. Background technique [0002] As people's demand for energy increases day by day, traditional non-renewable energy sources are less and less, and energy conservation and environmental protection have become more and more important. Therefore, developing low-carbon, environmentally friendly green energy and reducing energy consumption has become a An important topic in the field of scientific research. Compared with other forms of energy consumption, building energy consumption accounts for a large proportion of total energy consumption, especially in developed countries, where this proportion is close to 50%, and most of it is heating and air conditioning energy consumption. In my country, building energy conservation is more important, because compared with countries with ...
