coating sizing agent

SBR latex has good stability and fluidity, suitable for high-speed sizing machines, and can produce high-speed sizing paper products such as corrugated base paper, liquid packaging paper, etc. Compared with lignin latex, styrene-butadiene latex can achieve higher adhesive strength without hardening, so it is favored by the sizing industry.

SBR latex is a commonly used synthetic adhesive, and its coating process can be applied to a variety of papers, mainly including:

1. Glossy paper:

Coating styrene-butadiene latex on the surface of the paper can improve the surface smoothness and flatness, and improve the printing performance. Such as dyed paper, coated paper, etc.

2. Adhesive paper:

coated with styrene-butadiene latex to obtain adhesiveness, such as adhesive paper, tape base cloth, etc. SBR latex has excellent initial tack and adhesive strength, so it is suitable for adhesive paper products produced at high speed.

 

3. Composite materials:

composite functional materials such as plastic film and aluminum foil on the paper substrate through styrene-butadiene latex to obtain new functions. Such as fresh-keeping paper, metal foil paper, etc. SBR latex has good adhesion and can be used as a composite binder for various functional materials and paper substrates.

4. Anti-sticking paper:

Coating a small amount of styrene-butadiene latex on the surface of the paper can play the role of anti-sticking and anti-slip, and prevent sticking during high-speed production and conversion. Suitable for cardboard, thick paper and other products.

5. Functional paper:

Coating styrene-butadiene latex with functional materials on the surface of the paper can endow the product with special properties. Such as greaseproof paper, flame retardant paper, etc. SBR latex has strong miscibility and compatibility with various functional materials.

6. Decorative paper:
oating colored styrene-butadiene latex on the surface of the paper to improve the decorative effect and added value of the product.

The styrene-butadiene latex coating process can realize the effective modification and functionalization of the paper surface, and produce a variety of high value-added products. Different types of coating endow products with different properties and functions. This opens up an important avenue for the high-end and differentiation of paper products. Papermaking enterprises should choose appropriate styrene-butadiene latex and coating process according to product positioning and requirements, continuously develop new products and technologies, expand their application range, and realize high added value and sustainable development of enterprises.
