Abstract
The present invention relates to a waterproof agent and a preparation method thereof. The waterproof agent comprises the components of the following proportion by weight: 100 to 220 parts of alcohol, 45 to 60 parts of alkali, 1800 to 2000 parts of methyl trichlorosilane, 8000 to 12000 parts of ice and 10000 to 15000 parts of water. In the preparation method, the proportional water and the proportional ice are mixed firstly to obtain ice water; secondly, the alcohol which is proportionally added in the ice water is stirred; after the ice water and the alcohol are stirred uniformly, the methyl trichlorosilane is proportionally added; after being stirred uniformly, the ice water, the alcohol and the methyl trichlorosilane is kept for 3 to 4 hours at the temperature of 1 DEG C. below zero to 3 DEG C. below zero; the alkali which is added according to the proportion is stirred to obtain the waterproof agent, and then, the waterproof agent is heated to 80 DEG C to 95 DEG C, and the time of heating is 2 to 3 hours; finally, the density is adjusted between 1.02 and 1.04. The present invention has the advantages that the use performance of products is enhanced, namely that the waterproof time is shortened from 1 to 2 hours of the beginning to 5 to 10 minutes; the construction progress is accelerated; the preparation method is simple.
Description
The invention belongs to a kind of water-proof material and production technique thereof, particularly a kind of improved water-resisting agent and manufacture method thereof.
The input that China is used for the waterproof construction aspect is many year by year, at present, the ratio of waterproofing work cost reaches about 15% in project total cost, particularly the waterproof cost ratio of vault has reached the 25-30% of project total cost, although drop into so big, but waterproof effect is unsatisfactory, new construction then percolation ratio all about 10%.It is a lot of to make a general survey of present water-proof material market kind, as asphalt felt, SBS modification coiled material, BR water-resisting agent, BBI mortar water-proof material etc., these materials exist not ageing-resistant, behind poor water resistance, exposure cracking, the temperature influence and basic unit very easily throw off, produce shortcomings such as breach and hollowing, bigger in the complex region difficulty of construction, technical requirements is higher, wastes time and energy.For this reason, Jigong Inst. of Science-Education Development Technology, Changchun City has developed " a kind of waterproof material " (application number is 00110118.8), when being sprayed on brick, stone, sand-cement slurry, concrete product surface, can infiltrate its inner 10mm-20mm rapidly, form unchangeable waterproof layer, wear-resisting anti-wiping is because there is ventilation property, so can not chap, expand, distortion, weathering, also have anticorrosion, moistureproof, freeze proof acid and alkali-resistance, advantage such as high temperature resistant simultaneously.But on use properties, still there is certain deficiency, after in construction, making waterproof, needs 1-2 hour water-proofing time, just can carry out next step operation, thereby influence construction speed.
The purpose of this invention is to provide a kind of water-resisting agent and preparation method, enhance product performance, promptly shorten water-proofing time in the construction, accelerating construction progress, and the preparation method is simple.
The objective of the invention is to be achieved through the following technical solutions: its composition and part by weight are as follows:
Alcohol 100-220, alkali 45-60
METHYL TRICHLORO SILANE 1800-2000, ice 8000-12000,
Water 10000-15000
Preparation technology of the present invention is as follows: earlier pro rata water and ice are mixed, then alcohol is added in proportion in the frozen water and stirring, add METHYL TRICHLORO SILANE after stirring again in proportion, the back that stirs kept 3-4 hour under-1-3 ℃ condition, added pro rata alkali again and stirred, and heated then, temperature is 80-95 ℃, time is 2-3 hour, and adding water at last, to adjust density be 1.02-1.04 kilogram/cubic decimeter, product.
Advantage of the present invention is: improved the use properties of product, promptly the water-proofing time in the construction shortens, and shortens to 5-10 minute by original 1-2 hour, does not influence the carrying out of next step operation substantially, has accelerated construction speed, and the preparation method is simple simultaneously.
