Coatings and Adhesives
Styrene acrylic emulsion and acrylic emulsion are both important chemical products, which are widely used in coatings, adhesives and other fields. The following is a detailed introduction to them:
1. Styrene acrylic emulsion
Definition
Styrene acrylic emulsion is a synthetic resin emulsion obtained by emulsion polymerization of styrene and acrylic ester monomers.
Characteristics
Excellent water resistance: The coating film formed by styrene acrylic emulsion has good water resistance, can resist water erosion to a certain extent, and maintain the stability of the coating film.
Good weather resistance: It has a certain resistance to natural environmental factors such as sunlight, temperature changes, wind and rain, and is not prone to aging, discoloration, powdering and other phenomena.
Strong adhesion: It can firmly adhere to the surface of various substrates, such as wood, metal, plastic, paper, etc., providing good bonding properties for coatings and adhesives.
Good film-forming property: It can quickly form a film at room temperature to form a uniform and smooth coating film with high gloss and transparency.
Application field
Architectural coatings: used for interior and exterior wall coatings, providing good decorative and protective properties. Styrene acrylic emulsion coatings are washable, stain-resistant and durable, and can maintain the beauty and long-term use of buildings.
Adhesives: Used as adhesives in packaging, wood processing, paper processing and other industries, with high bonding strength and stability.
Textile printing and dyeing: Used for coating finishing of fabrics to give fabrics waterproof, oil-proof, antistatic and other functions.
Papermaking industry: As a paper surface sizing agent and coating adhesive, it improves the strength, smoothness and printability of paper.
2. Acrylic emulsion
Definition
Acrylic emulsion is a polymer emulsion made by emulsion polymerization of acrylic ester monomers or other vinyl monomers.
Features
Chemical corrosion resistance: It has good tolerance to chemicals such as acids, alkalis, and salts, and is suitable for applications in various chemical environments.
High transparency: The film has high transparency after film formation and does not affect the appearance and color of the coated object.
Good flexibility: The coating film has good flexibility and can adapt to the deformation of the substrate without cracking, which improves the durability of the coating.
Environmental protection: Generally, water is used as the dispersion medium, and it does not contain organic solvents, which reduces the pollution to the environment and the harm to the human body.
Application fields
Water-based coatings: Widely used in water-based coatings in the fields of construction, automobiles, wood, metal, etc., providing excellent decorative and protective properties.
Adhesives: Used for bonding various materials, such as paper, plastic, wood, metal, etc., with the characteristics of fast curing and high strength.
Textile auxiliaries: Used as finishing agents, adhesives and coating agents in the textile printing and dyeing industry to improve the feel, waterproofness and wear resistance of fabrics.
Leather finishing agents: Give leather good gloss, softness and friction resistance.
