preparation example Construction

[0035] A preparation method for an energy-saving and environment-friendly sealing primer, comprising the following steps:

[0036] Firstly, 1-9 parts by weight of auxiliary agents are dissolved in 100-150 parts of deionized water to form a first mixed solution.

[0037] Secondly, 17-43 parts by weight of acrylic acid, 24-39 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, 100-240 parts by weight of zinc powder are added and stirred evenly with a stirrer.

[0040] As a preferred solution, the preparation method of the energy-saving and environment-friendly sealing primer also includes adding 100-240 parts by weight of zinc powder after cooling the copolymer resin, stirring evenly w...

Embodiment 1

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

[0044] First, 1 part by weight of benzoyl peroxide, dimethylaniline and dimethyl phthalate in a weight ratio of 0.1:0.1:2 is dissolved in 100 parts of deionized water to form the first mixture.

[0045] Secondly, 43 parts by weight of acrylic acid, 24 parts of vinyl acetate and 0.1 part of n-butyl acrylate were added to 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, 100 parts by weight of zinc powder and 3 parts of bentonite were added and stirred evenly with a mixer.

Embodiment 2

[0049] This embodiment provides an energy-saving and environment-friendly sealing primer, the difference between its preparation method and the preparation method of the energy-saving and environment-friendly 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 100 parts of deionized water 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 the copolymer resin is cooled, 150 parts by weight of zinc powder and 8 parts of natural clay are added and stirred evenly with a m...

Abstract

The invention provides an energy-saving and environment-friendly seal primer and a preparation method thereof and relates to the field of coatings. The primer is prepared from the following components: 24-39 parts of vinyl acetate, 17-43 parts of acrylic acid, 100-150 parts of industrial deionized water, 0.1-0.3 part of n-butyl acrylate, 3-8 parts of an adsorbent, 1-9 parts of an assistant and 100-240 parts of zinc powder. The seal primer is good in environment-friendliness. The preparation method of the energy-saving and environment-friendly seal primer comprises the following steps of: dissolving the assistant in the industrial deionized water to form a first mixed solution; adding acrylic acid, vinyl acetate and n-butyl acrylate into the first mixed solution to be uniformly mixed to form a second mixed solution; pouring the second mixed solution into a reaction kettle and heating the reaction kettle to prepare copolymerized resin; and successively adding a zinc powder adsorbent into the cooled copolymerized resin and uniformly stirring the mixture. The method is simple and convenient and high in operability, and has relatively great industrial promotional value.

Description

technical field [0001] The invention relates to the field of coatings, and in particular to an energy-saving and environment-friendly sealing primer and a preparation method thereof. Background technique [0002] Coatings play an important role in the national economy and are indispensable in modern society. However, there are 10 million tons of volatile organic compounds (VOC) emitted into the atmosphere from coatings in the world every year, which are the main source of air pollution. With the continuous improvement of people's awareness of environmental protection and the promulgation of relevant regulations to limit VOC emissions, it has become the consensus of the entire society that environmentally friendly green coating products, with their characteristics of non-polluting and safe, can replace traditional heavily polluting solvent-based coatings. [0003] In recent years, with the progress of modern economy and the rapid development of science and technology, people...
