Embodiment 1

[0039]Put 48g of castor oil and 52g of 3A molecular sieve activation powder JLH-03B (45% exchange degree) produced by Luoyang Jianlong Chemical Co., Ltd. , to prevent agglomeration, etc., transfer the product mixed by the kneader to a multi-stage roll mill, and knead at 70 ° C for 30 minutes. The product is evenly mixed, does not hang on the wall, and has high fluidity and viscosity suitable for operation. Adsorption performance at room temperature: The water adsorption capacity is 5.4% in 12 hours, 7.8% in 24 hours, and reaches 12.5% ​​after more than 72 hours. As the adsorption time increases, the adsorption capacity does not increase. This sample has a moderate adsorption rate and will not fail due to strong water absorption due to short-term exposure to air, so it has stronger adaptability to the environment and is easy to operate in different environments.

Embodiment 2

[0041] Repeat Example 1, the difference is that 52g of castor oil and 48g of molecular sieve activation powder JLH-03B are added to the vacuum kneader, kneaded at 60°C for 1h, and then the product is transferred to a multi-stage roll machine, at 60°C Mixed for 20min. Normal temperature test adsorption performance 12h water adsorption amount is 5.6%, 24h water adsorption reaches 7.6%, after more than 72h water adsorption basically reaches saturation 12.1%.

Embodiment 3

[0043] Repeat Example 1, except that 30g of castor oil, 20g of dioctyl phthalate (DOP) and 50g of molecular sieve activation powder JLH-03B are added to the vacuum kneader, kneaded at 20°C for 1h, and then the product is transferred Put it into a multi-stage roller mill and knead for 10 minutes at 20°C. The adsorption performance of normal temperature test shows that the water adsorption capacity is 6.7% in 12 hours, reaches 9.7% in 24 hours, and basically reaches saturation of 12.3% after more than 72 hours.

Abstract

The present invention provides paste molecular sieve activation powder, a preparation method and an application thereof. The paste molecular sieve activation powder is a kneading material prepared by mixing 48-52% by mass of synthetic molecular sieve activation powder, 30-52% by mass of castor oil, and 0-20% by mass of a viscosity adjusting agent, wherein the synthetic molecular sieve activation powder is subjected to high temperature calcination dehydration. The paste molecular sieve activation powder of the present invention is applicable for raw material dehydration in fields of polyurethane coatings, paints and the like, wherein product performances are maintained, phenomena of blistering, attachment to the wall, and poor mobility can be prevented, and bad dispersion of the coating during a use process causes the phenomena.

Description

technical field [0001] The invention relates to a technology in the field of molecular sieve preparation, in particular to a paste-like molecular sieve activation powder and its preparation method and application. Background technique [0002] Reactive two-component coatings are currently a more common type of coating, usually divided into curing agent components and main agent components. There are many varieties of this type of coating, and the application range is also very wide. It has good mechanical properties and high solid content, and is currently a promising type of coating. The most common reactive two-component coating is two-component polyurethane coating, which is generally composed of isocyanate prepolymer and hydroxyl resin. Coatings, special coatings, polyurethane waterproof coatings, etc. [0003] Many reactive 2K coatings can react with traces of moisture in the system or the environment, eventually leading to the formation of air pockets, pinholes in th...
