preparation example Construction

[0035] A preparation method of an energy-saving thermal insulation sealing primer, comprising the following steps:

[0036] Firstly, 2-8 parts by weight of auxiliary agents are dissolved in 120-240 parts of industrial alcohol to form a first mixed solution.

[0037] Secondly, 16-52 parts by weight of acrylic acid, 10-45 parts of vinyl acetate and 0.1-0.3 parts of n-butyl acrylate are added to the first mixed solution and mixed uniformly to form a second mixed solution.

[0038] Then, pour the second mixed solution into the reactor and heat to prepare the copolymer resin, and the heating temperature is 60-70°C.

[0039] Then, after cooling the copolymerized resin, 200-320 parts by weight of zinc powder, 3-8 parts of titanium dioxide and 1-3 parts of ZnO are added and stirred evenly with a stirrer.

[0040] As a preferred solution, the preparation method of the energy-saving and heat-preserving sealing primer also includes adding 200-320 parts by weight of zinc powder after coo...

Embodiment 1

[0043] This embodiment provides an energy-saving and heat-preserving sealing primer, which is prepared by the following preparation method of an energy-saving and heat-retaining sealing primer. The method includes the following steps:

[0044] First, 2 parts by weight of benzoyl peroxide, dimethylaniline and dimethyl phthalate in a weight ratio of 0.1:0.1:2 are dissolved in 120 parts of technical alcohol to form the first mixture.

[0045] Secondly, 16 parts by weight of acrylic acid, 24 parts of vinyl acetate and 0.1 part of n-butyl acrylate were added into the first mixed solution and mixed uniformly to form a second mixed solution.

[0046] Then, the second mixed solution was poured into the reactor and heated to obtain a copolymer resin, and the heating temperature was 60°C.

[0047] Then, after cooling the copolymer resin, 200 parts by weight of zinc powder, 3 parts of titanium dioxide and 1 part of ZnO were added and stirred evenly with a stirrer.

Embodiment 2

[0049] This embodiment provides an energy-saving and thermal insulation sealing primer, the difference between its preparation method and the preparation method of the energy-saving thermal insulation primer provided in Example 1 is that the method comprises the following steps:

[0050] First, 5 parts by weight of benzoyl peroxide, dimethylaniline and dimethyl phthalate in a weight ratio of 0.1:0.1:2.5 are dissolved in 130 parts of industrial alcohol to form the first mixture.

[0051] Secondly, 30 parts by weight of acrylic acid, 25 parts of vinyl acetate and 0.2 part of n-butyl acrylate were added to the first mixed solution and mixed evenly to form a second mixed solution.

[0052] Then, the second mixed solution was poured into the reactor and heated to obtain a copolymer resin, and the heating temperature was 65°C.

[0053] Then, after cooling the copolymer resin, 220 parts by weight of zinc powder, 8 parts of titanium dioxide and 3 parts of ZnO were added and stirred e...

Abstract

The invention provides an energy-conservation and thermal-insulation seal primer and a preparation method thereof and relates to the field of coatings. The primer is prepared by the following method of dissolving 2 to 8 parts of additive into 120 to 240 parts of industrial alcohol to form a first mixed solution according to parts by weight; adding 16 to 52 parts of acrylic acid, 10 to 45 parts of vinyl acetate and 0.1 to 0.3 part of n-butyl acrylate into the first mixed solution to be evenly mixed to form a second mixed solution; pouring the second mixed solution into a reaction kettle to be heated to obtain copolymer resin; cooling the copolymer resin and sequentially adding 200 to 320 parts of zinc powder, 3 to 8 parts of titanium dioxide and 1 to 3 parts of ZnO to be evenly stirred by a stirring machine. The method has the advantages of simpleness and convenience, strong operability and larger industrial popularization value. The prepared seal primer has better corrosion resistance, no organic volatile matter overflow, environmental friendliness and energy conservation and further has excellent thermal-insulation efficiency.

Description

technical field [0001] The invention relates to the field of coatings, and in particular to an energy-saving and thermal insulation sealing primer and a preparation method thereof. Background technique [0002] The vast majority of buildings in our country are non-energy-saving buildings with high energy consumption. During the use of buildings, heating, air conditioning, ventilation, hot water supply, etc. consume a lot of energy, which accounts for about 30% of the total energy consumption of human beings. 40%. The national average of my country's energy utilization rate is only about 30%, while the energy utilization rate of industrially developed countries has reached more than 70%, and the loss caused by poor heat preservation accounts for a large proportion of heat energy loss. [0003] With the development of society and the requirements of low-carbon environmental protection, in order to maintain the internal temperature of buildings, reduce the consumption of air-c...
