Description
Technical field
The present invention relates to be used for the manufacture method of the solvent-type organosilicon waterproof liquid of porous substrate WATER REPELLENT.
Background technology
Existing waterproofing agent of organosilicon has aq. type, paste type, emulsion-type and powdery type.After these water-resisting agent disadvantage were to use a kind of waterproofing agent of organosilicon, it was very difficult to add another type water-resisting agent, and did not reach to cover and be coated with effect.And the depth of penetration of water-resisting agent in base material is little, can lose waterproof effect through after the weather aging of certain hour.Along with the raising of environmental requirement, can not contain in the solvent of finishing material healthy toxic and environment is had a material of pollution.For ease of construction, require to select different type of solvent, to reach the requirement of different time of drying in the construction according to the variation of solvent in temperature.
Summary of the invention
The objective of the invention is to problem, a kind of manufacture method of solvent-type organosilicon waterproof liquid is provided at the prior art existence.
The manufacture method of solvent-type organosilicon waterproof liquid of the present invention comprises: after one or more mixtures in active organosilicon alkane, active organosilicon oil, the active organosilicon resin are stirred, feed N
