Latex products, special lipophilic modified nano-silica

Latex products, special lipophilic modified nano-silica pure latex mechanical strength is low, when mixed with nano-silica (VK-SP30) reinforcing fillers, nano-silica aggregates of silicone emulsion has a good reinforcing effect After adding latex nano-silica (VK-SP30) powder, forming a microcrystalline silica nucleation zone, increasing the physical crosslinking points, more crystallization occurs, latex strength can be increased by 40 times the more. Product Specifications: Item Index Appearance white like the end Model VK-SP30 average particle size, nm 5-40 surface area, m2 / g 200 ± 50 content% ≥99.8 PH value of 3.5-4.5 Loss on ignition (%) 950 ℃ x2h ≤ 1.0 nano-silica application characteristics of latex:? as a reinforcing agent, anti-aging agent, nanometer silicon dioxide (VK-SP30) applied latex products, latex products can increase strength and improve toughness, anti-aging, anti- friction fire, prolong life and other features. Due to the small size effect of nano-silica nanoparticles and a large specific surface area; the other hand, because it contains a lot of silicon surface light-yl, particles may form a network structure by the action of hydrogen bonding and van der Waals forces, while silica particles also will work with the silicone molecules interact strongly improved interface status. Nano-silica reinforcement of silicone emulsion by their particle size, specific surface area and structural effects, generally smaller the particle size, larger specific surface area, structural higher, reinforcing the better, of vulcanized rubber strength, the higher the hardness. Addition: silicon emulsion: 3.0-30%; polysulfide latex: 0.1-5%; polyurethane: 3.0-25%; acrylates: 0.5-3.5% nano-silica (VK-SP30) in the latex, the We must pay attention to the degree of dispersion in the polymer. Nano-silica dispersion in the system affect the performance of latex is very large, transparent plastic material system, the greater the transparency the better indicate the degree of dispersion of nano-silica. Packaging: 10 kg / bag Storage: nano-silica should be stored in a dry, airtight environment, without exposure to volatile substances. Xuancheng Jing Rui New Materials Co., Ltd.
