Acrylic emulsion HT-9809 for back coating of thermal insulation cotton
Appearance and physical properties
Acrylic emulsion for back coating of thermal insulation cotton is usually milky white or nearly transparent viscous liquid, with a pH value between 8 and 9 (25°C), a viscosity range of 3000~8000mPa·s, and a solid content (150°C, 20min) of 49%~51%. These physical properties enable acrylic emulsion to be well combined with thermal insulation cotton materials to form a uniform coating.
Chemical properties
Excellent adhesion: Acrylic emulsion has good adhesion to the surfaces of various materials such as masonry, wood, and steel, which can ensure the firm bonding of thermal insulation cotton with substrates such as walls.
Water resistance: Acrylic emulsion has excellent water resistance, can resist water erosion, and ensure the stability and durability of thermal insulation cotton back coating in humid environments.
Weather resistance: Acrylic emulsion can resist the influence of bad weather, such as high temperature, low temperature, ultraviolet rays, etc., thereby extending the service life of the insulation cotton.
Alkali resistance: Acrylic emulsion has good stability in alkaline environment and is suitable for construction and use under various alkaline conditions.
Anti-fouling: Acrylic emulsion can resist the adhesion of stains and keep the back glue of the insulation cotton clean and beautiful.
Environmental performance
Acrylic emulsion is non-toxic and pollution-free, meeting the requirements of modern green environmental protection. During production and use, it will not cause harm to the human body and the environment.
Application characteristics
Convenient construction: Acrylic emulsion has excellent construction performance, is easy to apply and dry, and can improve construction efficiency.
Strong bonding: Acrylic emulsion as an adhesive can ensure the close bonding between the insulation cotton and the wall and other substrates, and improve the insulation effect.
Good durability: Acrylic emulsion has good durability and stability, which can ensure that the back glue of the insulation cotton maintains excellent performance during long-term use.
Application field
Acrylic emulsion for back glue of insulation cotton is widely used in construction, automobiles, home appliances and other fields. In the construction field, it is mainly used for pasting thermal insulation materials inside and outside the building wall to improve the thermal insulation performance of the building; in the automotive field, it can be used for sound insulation and heat insulation of automobile chassis, engine hood and other parts; in the home appliance field, it can be used for thermal insulation of refrigeration systems of home appliances such as refrigerators and air conditioners.
Precautions
Storage conditions: It should be stored in a dry, cool and ventilated place, avoiding direct sunlight and high temperature.
Construction environment: During construction, the ambient temperature and humidity should be appropriate, and construction should be avoided under extreme weather conditions.
Surface treatment: Before bonding, the bonding surface should be cleaned and treated to ensure that there are no impurities such as oil, dust, etc.
Glue application control: The amount of glue should be controlled to avoid too much or too little to ensure the bonding effect and save materials.
In summary, the acrylic emulsion for back coating of thermal insulation cotton has excellent adhesion, water resistance, weather resistance, alkali resistance and environmental protection performance, and is suitable for pasting thermal insulation materials in various fields. When using it, attention should be paid to storage conditions, construction environment, surface treatment and glue application control to ensure its optimal performance and effect.
