AI Technical Summary

Problems solved by technology

However, when effectively reducing the tightness of the MS sealant, water molecules easily enter the colloid, resulting in a decrease in the viscosity of the MS sealant
In addition, MS sealants are prone to accelerated colloidal aging due to ultraviolet radiation and short service life. Therefore, adding additional UV absorbers can effectively block the damage of ultraviolet rays to the colloid. However, most of the current UV absorbers are small molecules. It is easy to volatilize, it is difficult to achieve the barrier effect, and the purpose of prolonging the service life cannot be achieved

Embodiment 1

[0033] A preparation method of MS sealant with insect repellent and anti-ultraviolet aging, the preparation method comprises the following steps:

[0034] 1) Mix 0.5g of styrene, 0.5g of methyl methacrylate, 1g of citronella essential oil, 0.5g of 2-[3-(2-benzotriazol-2-yl)-4-hydroxyphenyl]methacrylic acid Ethyl ester, 0.5g ammonium octachloride propyl silsesquioxane, 0.1g alkylphenol polyoxyethylene ether, 0.1g sodium dodecylbenzenesulfonate, 0.1g sodium bicarbonate and 1ml acrylic acid dissolved in 80ml distilled water Then, the mixture was emulsified at a speed of 300rpm / min for 15 minutes. Finally, the obtained emulsion was poured into a 500ml four-necked flask, and argon gas was introduced for 30min. After the temperature was raised to 60°C, 5ml of 1wt% The initiator ammonium persulfate solution was added until the dropwise addition was completed, and the polymer containing citronella essential oil was obtained after continuous stirring and reaction for 3 hours.

Abstract

The invention discloses an MS sealant with insect repellent and anti-ultraviolet ageing properties and a preparation method. In parts by weight, it includes at least the following components: 5-25 parts of silane oligomers, 5-20 parts of fluorine-terminated hydroxyl-terminated polyethers, 0.1-0.5 parts of catalyst, 1-5 parts of dehydrating agent, and 5-20 parts of plasticizer , 15‑30 servings of filler, and 0.1‑0.5 servings of multifunctional POSS-based microcapsules. The invention adopts silane oligomer and fluorine-terminated hydroxyl polyether to generate silane-modified polyether resin under the catalytic condition of organic tin catalyst, and then mixes silane-modified polyether resin with filler, viscosity promoter, gas-phase silica, enhancer A kind of MS sealant with insect repellent and anti-ultraviolet aging was prepared by the joint reaction of plasticizer and multifunctional POSS-based microcapsules. The synthesis method has the advantages of mild reaction conditions, readily available reaction raw materials, and easy operation of the reaction process; and compared with traditional MS sealants, it has excellent performance in repelling insects, anti-erosion, anti-ultraviolet aging, and anti-wetting.

Description

technical field [0001] The invention belongs to the field of adhesive materials, and relates to an MS sealant with insect repellent and anti-ultraviolet ageing properties and a preparation method. Background technique [0002] MS sealant is a high-performance adhesive based on silane-modified polyether resin. It has the advantages of excellent adhesion, weather resistance, environmental protection and paintability. It is widely used in construction engineering and decoration. Bonding, caulking, joints, sealing, waterproofing, reinforcement and other fields. [0003] At present, the research on MS sealant has been devoted to improving the viscosity, but there is little research on the functionality of life applications. For example, MS sealant is often used in the bonding of wood materials, and it is well known that wood is easily eroded by insects. If a kind of MS sealant with insect resistance can be developed, and the insect repellent drug is encapsulated in the adhesive ...
