Waterproof agent (Water Repellent)

Acrylic resin

Thermoplastic resin and thermosetting resin

Thermoplastic resins have a high molecular weight and are difficult to crosslink during film formation. They have good color and light retention properties, excellent waterproofing, chemical corrosion resistance, and are easy to apply and rework.

Thermosetting resins mostly have low molecular weight and carry active functional groups on their side chains, which can undergo cross-linking through self reaction or reaction with other resins. Thermosetting resin has good color retention at high temperatures, does not change color or turn yellow, and also has good glossiness, hardness, fullness, etc.

Acrylic resin is an organic substance, and most of its functional groups are hydrophobic groups. The acrylic resin polymer synthesized by lotion polymerization is insoluble in water. The organic molecular chain of the acrylic resin polymer synthesized by lotion polymerization has a part of functional groups with ionic properties and can be compatible with water. The waterproof performance is affected to some extent, but its own waterproof performance will be affected to some extent.

The specific principle of using acrylic resin copolymer to process paper is that using a small amount of acrylic resin can reduce the surface tension of water to a very low value. When using acrylic resin to treat paper, first make it adsorbed on the fiber surface, after baking, lotion forms a film, hydrophobic groups are closely arranged on the paper surface, the paper has a very low surface energy, and water is difficult to wet. Achieved the waterproof effect of paper. Acrylic resin itself is also a high molecular weight waterproofing agent. As a functional monomer, it participates in the reaction and is used to make coatings. After being made into coatings, the coatings also have certain waterproofing properties. Depending on the formula, reactants, and synthesis methods, coatings with different effects can be made.

Paper treated with acrylic resin has considerable hydrophobicity and can be widely used in hydrophobic paper, such as photographic paper, map paper, photo books, special paper, etc. The treated paper has a low resin content, which does not affect the degradation of paper products, is green and safe, and does not cause harm to human body and nature. It can also be applied in the catering industry, gradually replacing plastic products.

Coatings processed with acrylic resin have excellent performance, strong gloss, good light resistance, oil and grease resistance, acid and alkali corrosion resistance, stable chemical properties, and can be stored for a long time. They are widely used in automotive construction, small household appliances, and even leather.

Inorganic nanoparticles as crosslinking points in the acrylic resin polymer matrix can limit the thermal movement of large molecular chains in the resin through both physical and chemical crosslinking, thereby increasing the glass transition temperature of composite materials. This beneficial modification has the potential to be applied in both water and high temperature resistance of paper waterproofing agents and modification of water-based coatings.
