Embodiment Construction

[0029] A method for producing a neutral transparent silicone weather-resistant sealant for lighting roofs, characterized in that the silicone sealant is prepared from the following materials according to the weight ratio:

[0030] 20000 viscosity (25°C, mpa.s) room temperature vulcanized methyl silicone rubber 450-500 parts

[0031] 500000 viscosity (25℃, mpa.s) room temperature vulcanized methyl silicone rubber 200-230 parts

[0032] 70-80 parts of simethicone oil

[0033] Fumed silica 80-90 parts

[0034] Methyl tributylketoxime silane 35-38 parts

[0035] Vinyl tributylketoxime silane 5-6 parts

[0036] N-(B-aminoethyl)-Y-aminopropyltrimethyl(ethyl)oxysilane 1.5-2 parts

[0037] γ-Aminopropyltriethoxysilane 2-2.5 parts

[0038] γ-glycidyl etheroxypropyl trimethoxysilane 1.5-2 parts

[0039] Dibutyltin dilaurate 1-1.5 parts

[0040] The production steps are as follows:

[0041] (1) After the 1100L high-speed disperser is started, 20,000 viscosity room temperature vul...

Abstract

The invention provides a production method of neutral transparent silicone weather-resistant sealing adhesive dedicated to a daylighting roof. The neutral transparent silicone weather-resistant sealing adhesive dedicated to the daylighting roof is prepared by mixing room-temperature vulcanized methylsilicone rubber, dimethyl silicone oil, vapor-phase method silicon dioxide, methyl tributanone oxime silane, vinyl tributanone oxime silane, N-(B-amino ethyl)-Y-ammonia propyl trimethyl(ethyl)oxyl silane, gamma-amopropyl triethoxy silane, gamma-glycidyl ether oxopropyl trimethoxysilane and dibutyltin dilaurate according to weight proportion, wherein the room-temperature vulcanized methylsilicone rubber is a supporting raw material; the dimethyl silicone oil, white mineral oil and the vapor-phase method silicon dioxide are filling raw materials and the other are functional aids. The invention provides a production method of a neutral transparent silicone weather-resistant sealing adhesive byaiming at the problems that the silicone adhesive dedicated to the daylighting roof has low compatibility and anti-displacement ability not up to the standard, and high compatibility on a glass daylighting roof, a polycarbonate daylighting roof and a film structure daylighting roof is achieved, and the structure adhesion and weather-resistant sealing requirements can be met simultaneously.

Description

technical field [0001] The invention relates to a production method of a neutral transparent silicone weather-resistant sealant for a daylighting roof, in particular to a production method of a single-component deoxime-type neutral transparent silicone weather-resistant sealant for a daylight roof. Background technique [0002] With the development of technology and the improvement of building quality requirements, buildings centered on human comfort pay more attention to the relationship between buildings and nature, which not only makes buildings more beautiful, but also promotes building energy efficiency. The lighting roof makes full use of natural light and integrates the indoor and outdoor environments. It is favored by architects. The increasingly diverse materials provide architects with more choices. At present, the daylighting roofs that are widely used in the market mainly include glass daylighting roofs, polycarbonate daylighting roofs and membrane structure dayl...
