Abstract
Alpha, omega-dihydroxypolysiloxane can be used as base material, silane internal plasticzer and its auxiliary additives, such as methylhydroxyl dimethylsilane, silicon dioxide, methyltrimethoxysilane and organotitanium and organotin compound, etc. are troduced, they are chemically reacted under the condition of that vacuum is 0.06-0.095 MPa so as to obtain the invented neutral silicone stone sealant.
Description
The present invention relates to a kind of neutral silicone sealant for stone material and manufacture method thereof, belong to the polymer building material field.
Silicone sealant has excellent weather, damp and hot, ultraviolet ray and ozone ageing performance thereof, is one of building sealant preferred material.Along with the widespread use of building curtain wall, silicone sealant has obtained swift and violent development.The dry-hang stone curtain wall rises rapidly, and stone material has become one of decoration of exterior wall main flow of top-grade building, so the application quantity of silicone sealant increases year by year.In order to improve the elongation of neutral silicone seal gum, reduce hardness, increase elasticity, improve extrudability, usually will add some softening agent in seal gum, as dioctyl phthalate (DOP), low viscosity methyl-silicone oil etc., these softening agent can not participate in cross-linking and curing reaction, after for some time, softening agent will be exuded to stone surface from colloid, pollute stone material, have a strong impact on the attractive in appearance and decorative quality of curtain wall.Chinese patent CN1110299A is entitled as " organic silicone structure sealant ", and it is made by raw materials such as organic silicone and silicate, can be used for the sealing structure of glass curtain wall aspect, but does not solve the pollution problem of silicone adhesive to stone material.
The objective of the invention is provides a kind of neutral silicone sealant for stone material and manufacture method thereof at the deficiencies in the prior art, being characterized in adopting α, alpha, omega-dihydroxy polysiloxane is base-material, introduce reactive silane softening agent and supplementary additive thereof, make the free of contamination neutral silicone sealant for stone material of stone material.
Purpose of the present invention is realized that by following technical measures wherein said raw material umber is parts by weight except that specified otherwise.
