Description
Technical Field
The invention relates to the technical field of sealants, in particular to an acrylic ester sealant for buildings and a preparation method thereof.
Background
The water-based acrylate sealant has the characteristics of environmental protection, good weather resistance, good elasticity, low price and the like, and meanwhile, the structure of the acrylate has high polarity and high saturability, so that the acrylate sealant has excellent mineral oil resistance and high-temperature oxidation resistance. Based on the advantages, the acrylate material becomes one of four major sealants of building structures, and compared with the traditional silicone and polysulfide sealants, the acrylate material is more in line with the relevant policy of vigorously popularizing green building materials in China.
At present, the modification of the acrylate sealant for buildings mostly focuses on the aspects of adhesiveness, durability, curing speed, stain resistance and the like, and no special introduction and research is made on the shrinkage resistance of the acrylate sealant for buildings in the papers and patents.
The acting force between the monomers of the acrylate sealing material before curing is Van der Waals force, the curing process of the acrylate sealing material is accompanied with the processes of dehydration and crosslinking, the acting force between the monomers after curing is changed into covalent bond force, the monomers are connected in a covalent bond form to form a stable three-dimensional network structure, the distance between molecules is changed from 0.3-0.4 nm to about 0.15nm, the distance between the monomers in the resin is reduced, and thus the volume is shrunk during polymerization macroscopically.
The high shrinkage problem of acrylate sealants is severe and causes undesirable consequences including: (1) when the sealant is applied to the outer wall of an assembly type building, a weak layer of the sealant is formed at the edge part of the wall board, so that a stressed weak point is formed, and cracking is easily formed during displacement, so that the water leakage problem is caused; (2) when the acrylate sealant is applied to the built-in light partition board, the sealant shrinks to cause the depression of the joint of the wall surface, and the unevenness of the wall surface can be increased when the wall surface coating is coated, so that the attractiveness of a building can be influenced. Therefore, the problem of high shrinkage of the acrylate sealant is a necessary way for popularizing the large-scale application of the acrylate sealant.
