Abstract
The present invention relates to a preparation method for an organic silicon waterproof agent for building, particularly to a preparation method for a silicon resin gelatinizer. The discarded silicone resin gelatinizer is used as the raw material; according to the difference of discarded substances and the input amount of the discard silicone resin, equal amount of 30% of NaOH aqueous solution is added, the mixture is heated to about 120 to 140 DEG C and is dissolved for 2 to 3 hours, and the organic silicon waterproof agent is prepared by cooling, filtering, testing and adjusting solid content. The present invention has the advantage of simple and convenient operation; simultaneously, the present invention solves the problems that the silicon resin is difficult to be removed because of the gelatination and the cementation of the silicon resin and human power and material resources are wasted, so labor intensity is greatly reduced; simultaneously, a useful product-the organic silicon waterproof agent for building is obtained.
Description
Technical field
The present invention relates to a kind of preparation method of organosilicon waterproof agent for building, particularly a kind of method for preparing the organosilicon waterproof agent for building with silicone resin gel thing.
Background technology
Waterproof agent for building is a kind of sodium silanolate aqueous solution, be diluted with water to 3～5% the aqueous solution during use according to a certain percentage, spray or brush in brick, watt, material surfaces such as building stones, cement products, buildings do waterproof, protection against the tide, anti-pollution, weathering resistance, the anti-effects such as cracking that cause because of cold cycling.Simultaneously can also do plastering and concrete waterproof toughener.With in Tai-Ace S 150 or the aluminum nitrate and after, can also be applied to aspects such as timber, fiberboard, woodwork plate, paper and processed goods thereof and make water-resisting agent and use.At present, the organosilicon waterproof agent for building is by CH
3SiCl
3Hydrolysis, being washed to neutrality, producing the white powder solid, is alkaline aqueous solution---the methyl silicon sodium alcoholate of making after the NaOH aqueous solution heat fused again with the weight percent.
Summary of the invention
The purpose of this invention is to provide a kind of method for preparing the organosilicon waterproof agent for building with silicone resin gel thing.
The technical solution adopted for the present invention to solve the technical problems is: the organosilicon waterproof agent for building is to adopt silicone resin gelatinoid and NaOH aqueous solution heat fused to form.Promptly adopting the silicone resin gelatinoid of scrapping is raw material, according to the difference of scrappage, and scraps the silicone resin input amount, and adding weight percent is the 30%NaOH aqueous solution, and about 120～140 ℃, 2～3h is dissolved in heating, cooling, filtration.
The present invention is simple for process, solved simultaneously the silicone resin gel that causes because of a variety of causes, glued in still easy-clear not, cause the loaded down with trivial details of manpower and materials waste, greatly reduce labour intensity, obtained useful product simultaneously---the organosilicon waterproof agent for building.
This organosilicon waterproof agent for building is a kind of silicone resin waste ' s reclamation that utilizes, and is the utilization again of resource, turns waste into wealth.Solved in the past in producing silicone resin, and the difficult problem that can't handle of the resin gel that causes of storage and other factors, this technology is except that the waste that utilizes silicone resin is produced the organosilicon waterproof agent for building, to be contained in the poisonous and harmful solvent recuperation utilizations such as benzene class in the silicone resin simultaneously, thereby reduce environmental pollution.
Embodiment
Prepare the method for organosilicon waterproof agent for building with silicone resin gel thing, have following technical process:
A. will scrap the block that silicone resin is ground into powdery or is not more than 2～3cm, put in the reactor;
B. weight percent is put in the still for the 30%NaOH aqueous solution;
C. in 1.5h, slowly be warming up to 120～140 ℃, under this temperature, be incubated 2～3h, decide,, become fraction and get final product until no block on situation in the still;
D. be cooled to below 40 ℃, remove by filter impurity.
Claims (1)
1, a kind ofly prepare the method for organosilicon waterproof agent for building, adopt silicone resin gelatinoid and NaOH aqueous solution heat fused to form, it is characterized in that having following technical process with silicone resin gel thing:
A. will scrap the block that silicone resin is ground into powdery or is not more than 2～3cm, put in the reactor;
B. weight percent is put in the still for the 30%NaOH aqueous solution;
C. in 1.5h, slowly be warming up to 120～140 ℃, under this temperature, be incubated 2～3h, decide,, become fraction and get final product until no block on situation in the still;
D. be cooled to below 40 ℃, remove by filter impurity.
