Abstract
The invention provides a mildew-proof sealant and a preparation method thereof. The mildew-proof sealant adopts a system totally different from a silicone adhesive structure, overcomes the defect of a poor mildew-proof effect of traditional mildew-proof silicone sealants, has brightness like a ceramic glaze after the product is cured, is applied to ground and wall pointing and internal corner trimming of high-grade home space, hotels and business places as well as trimming and beautifying of closestools, kitchen countertops, partitions of shower rooms, balconies, windowsills and the like, and can completely eliminate household hygiene dead angles, and the mildew-proof, the anti-fouling and anti-yellowing performance and the like are improved substantially. Besides the above-mentioned effects, the storage stability is high, and the use performance is basically unchanged after the sealant is stored for two years.
Description
Technical field
The present invention relates to seal gum field, be specifically related to a kind of mildewproof sealant and preparation method thereof.
Background technology
Silicone sealant is the macromolecular compound of polymethyl siloxane and silicone cross-linked formation siloxane bond (Si-O key) tridimensional network, its Si-O key bond energy is up to 425KJ/mol, be far longer than carbon-carbon bond (C-C key) bond energy (345KJ/mol) and carbon-oxygen bond (C-O key) bond energy (351KJ/mol), therefore good stability.There is very strong weathering resistance, add polysiloxane molecule volume large, cohesive energy density(CED) is low, it is made to have excellent stain resistant, resistant of high or low temperature, height hydrophobicity and good ventilation property etc., can within the scope of-60 ~ 200 DEG C life-time service, its mechanical property is as very little in changes such as tensile strength, tear strength, elongation, hardness, is therefore widely used in building, electronics, automobile and other industries.
Since the eighties in 20th century, along with prefabricated, the high stratification of domestic construction and a large amount of employings of glass, metal curtain wall flexible structure and large-scale frame cladding panel structure, larger demand is proposed to high-grade resilient silicone seal gum, and to the balance of its quality, over-all properties, all propose requirements at the higher level to the aspect such as adaptability and operation performance of base material and varying environment, greatly facilitate the fast development of domestic resilient silicone seal gum, the application as the important branch product-mildew-resistant silicone sealant of silicone adhesive also extend to rapidly house ornamentation field.
Along with socioeconomic development, people's quality of the life is improving constantly, also more and more harsher to the requirement of house decoration details.Mildew-resistant silicone sealant has played irreplaceable effect in house decoration as sealing material, but, there is following shortcoming in traditional mildewproof sealant on the market: mildew-resistant timeliness is short, generally within some months to year, loses antimildew function gradually.As seal gum is applied in dark or moist environment such as the interface of Kitchen tap tank and table top, toilet wash platform and body of wall interface, waterproof sealing between bathtub and body of wall, toilet and the interface area on ground, the interface area between living room floors and metope etc., easily produce after short period that mould causes colloid surface to turn black, jaundice, greening or the inconsistent color of other and colloid, affect attractive in appearance.For this reason, above problem is solved in the urgent need to a kind of mildewproof sealant of efficient stable in market, to keep the perfection of fitting up details, allows bacterium spot have no place to hide, and makes healthy clean space.
In addition, also there is the shortcoming of poor storage stability in current mildewproof sealant, the storage life is low, and within general about 1 year, namely performance declines to a great extent, and affects the use of product.
