ACRYLATE SEALANT FOR CONSTRUCTION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/040076
Kind Code:
A1
Abstract:
The present invention relates to the technical field of sealants, and in particular, to an acrylate sealant for construction and a preparation method therefor. The acrylate sealant for construction comprises preparation raw materials of: 85-95 parts of acrylic emulsion; 1-10 parts of modified hollow ceramic microsphere; 0-5 parts of coupling agent; 0.2-5 parts of coalescing agent; 0.1-5 parts of thixotropic agent; and 0.1-5 parts of other additives. The modified hollow ceramic microsphere is obtained by modifying a hollow ceramic microsphere using a modifier; and the modifier comprises maleic anhydride and stearic acid. According to the present invention, the hollow ceramic microsphere modified by a specific component is added to the acrylate sealant for construction, which effectively improves the compatibility of the hollow ceramic microsphere and the acrylate sealant, and further reduces the loss of mechanical properties such as elasticity caused by the addition of a filler. Moreover, the modified hollow ceramic microsphere cooperates with other components to further improve the anti-shrinkage performance of the acrylate sealant for construction.
