Oil based polyurethane zeolite molecular sieve powder (also commonly referred to as oil-based two-component polyurethane defoaming powder molecular sieve or polyurethane molecular sieve powder) has significant application effects in improving colloidal physical properties. The following is a specific explanation of its application:

1. Application background

Oil based polyurethane zeolite molecular sieve powder is prepared by high-temperature calcination based on polymer adsorbent raw powder, adding stabilizers or suspending agents. This preparation process makes zeolite powder highly active and can be directly applied as an adsorbent with selective adsorption in production.

2. Application effect

1) Adsorbed impurities:

In polyurethane products such as coatings, adhesives, and sealants, oil-based polyurethane zeolite molecular sieve powder can adsorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself, thereby improving the stability and physical properties of the product.

2) Adjust curing time:

In two-component polyurethane adhesives, molecular sieve activated powder can adjust the curing time, leaving sufficient margin for construction operations, thereby ensuring construction quality and physical properties of the product.

3) Improve uniformity and strength:

The uniform dispersion of oily polyurethane zeolite molecular sieve powder in polyurethane materials helps to improve the uniformity and strength of the material, making the product more durable and thus enhancing its physical properties.

4) Selective adsorption:

In specific polymers or coatings, oil-based polyurethane zeolite molecular sieve powder can also serve as a selective adsorbent to adsorb harmful gases such as CO2 and H2S generated during the production process, thereby ensuring the safety and health of the production environment and indirectly improving the physical properties of the product.

3. Application Fields

1) Polyurethane coating:

Molecular sieve activated powder can be used as a water removal agent to remove moisture from coatings, prevent the formation of bubbles and delamination during storage and use, and ensure the physical properties and appearance quality of coatings.

2) Polyurethane adhesive:

In the preparation process of polyurethane adhesive, adding molecular sieve activation powder can eliminate bubbles in the adhesive, improve bonding strength and durability, and meet various bonding requirements.

3) Polyurethane elastomer:

In the production of polyurethane elastomers, molecular sieve activated powder can be used to adjust the viscosity and flowability of materials, ensuring that the elastomers have good physical and processing properties.

4) Other fields:

Oil based polyurethane zeolite molecular sieve powder can also be used in epoxy zinc rich coatings to inhibit the reaction between moisture and zinc, and enhance the anti-corrosion performance of the coating. In addition, it can also be used in the production of insulating glass strips to remove moisture from coatings and sealing materials during the window manufacturing process, ensuring the sealing and durability of the product.

In summary, oil-based polyurethane zeolite molecular sieve powder has broad application prospects and significant advantages in improving colloidal physical properties. By removing impurities, adjusting curing time, improving uniformity and strength, and selectively adsorbing, it can effectively enhance the physical properties and quality of polyurethane products.
