Pure acrylic emulsion is an important raw material for chemical production, which is widely used in coatings, adhesives, fabric treatment and other fields. This article will detail the properties and uses of pure acrylic emulsion.

1. the properties of pure acrylic emulsion

pure acrylic emulsion is a polymer emulsion prepared by emulsion polymerization of acrylate monomers. It has many excellent properties, including:

1. good water resistance: pure acrylic emulsion in the polymer molecular chain is hydrophobic, making the emulsion has good water resistance.

2. excellent weather resistance: pure acrylic emulsion polymer molecular structure stability, can resist ultraviolet, oxygen and other natural factors of erosion, has good weather resistance.

3. Good adhesion: the polymer molecular chain in pure acrylic emulsion has polar groups, which can produce good adhesion with many material surfaces.

4. High solid content: The solid content of pure acrylic emulsion is high, and high-concentration products can be prepared, which is conducive to reducing transportation and use costs.

2. the use of pure acrylic emulsion

pure acrylic emulsion as an important chemical raw material, widely used in the following fields:

1. coating field: pure acrylic emulsion can be used as the main film-forming coating material, used in construction, furniture, automobile and other surface coating. It has excellent water resistance, weather resistance and decoration, and can extend the service life of the coated object.

2. adhesive field: pure acrylic emulsion can be used as the main component of adhesive, used for the adhesion of wood, paper, leather and other materials. It has excellent adhesion and water resistance, and can improve the strength and durability of the adhesive.

3. fabric treatment field: pure acrylic emulsion can be used for fabric coating and finishing, improve the fabric waterproof, breathable and elastic properties.

3. pure acrylic emulsion production process

pure acrylic emulsion production process mainly includes monomer emulsification, polymerization, post-treatment and other steps. The specific production process is as follows:

1. Monomer emulsification: The acrylate monomer, emulsifier and water are mixed, and a stable monomer emulsion is formed by high-speed stirring.

2. Initiating polymerization: An initiator is added to the monomer emulsion to initiate the polymerization of the acrylate monomer to generate a polymer emulsion.

3. post-treatment: by adjusting the pH value, adding preservatives and other post-treatment agents to improve the stability and storage of pure acrylic emulsion.

4. the development trend of pure acrylic emulsion

With the continuous development of science and technology, the performance and application fields of pure acrylic emulsion are also expanding. In the future, the development trend of pure acrylic emulsion is mainly reflected in the following aspects:

1. environmental protection development: with the improvement of people's awareness of environmental protection, the production and use of pure acrylic emulsion in the future will pay more attention to environmental protection and reduce environmental pollution.

2. high performance development: by improving the production process and optimizing the formula, improve the performance index of pure acrylic emulsion, meet the application needs of more fields.

3. multi-functional development: by compounding other functional materials, giving pure acrylic emulsion more functions and expanding its application fields.

In conclusion, as an important raw material for chemical production, pure acrylic emulsion has broad application prospects and great development potential. In the future, with the continuous progress of science and technology and the continuous expansion of application fields, pure acrylic emulsion will play an important role in more fields and make greater contributions to the development of human society.
