Abstract
The present invention discloses waterproof paint which can be directly used on water seepage concrete surfaces. The waterproof paint comprises a basic material containing epoxy resin and a solidifying agent containing amine compounds. The waterproof paint of the present invention can be directly used in water, so the construction method is simple, and the waterproof paint has the advantages of high adhesive force between paint and interfaces, high impermeability, little pollution to the environment, etc.
Description
Technical field
The present invention relates to a kind of waterproof paint, particularly a kind of can be on creepage concrete surface direct solidified coating.
Background technology
Present wet surface waterproof paint only is applicable to that generally water ratio is less than 8% building concrete basic unit.Construction environment is very moist under many situations, even infiltration but in actual applications.Be covered with under the situation that water molecules forms sealing coat in substrate surface, polymer substance can't be taken root in basic unit or be produced strong gravity with basic unit solid molecule, and firm sticking power can not be arranged, certainly will easy peeling, peel off, thus lose water-proof function.
" Shanghai chemical industry " 23 the 5th phases of volume had once been reported the polyurethane water-proof paint that can be applicable to wet state of saturation concrete base layer.The definition of wet state of saturation is that concrete base layer soaks the state when drying surface area water after 24 hours in water.But this coating can not directly apply to the concrete base layer of open fire or ponding, infiltration.Report two-pack polyether(poly)urethane waterproof paint was also once arranged, the solidifying agent that its second component is a hydroxyl, softening agent, weighting agent and extraordinary reactive component.This extraordinary reactive component can be converted into polyurethane cross-linking agent with water, and the introducing of hydroxyl in the second component has increased the affinity between coating and the basic unit, so this coating does not foam on wet surface, have stronger cementability, but the sticking power of filming reduces significantly then when the infiltration surface construction.Also there are same problem with fixed attention in other waterproof paint such as cyanogen.
Summary of the invention
The objective of the invention is to, a kind of waterproof paint that is directly used in creepage concrete surface is provided.
Technical scheme
The said waterproof paint of the present invention comprises: contain the base material component and the curing agent component that contains aminated compounds of Resins, epoxy, the mass ratio of base material component and curing agent component is 1-10: 1.
Said base material component comprises following component and content (content is in mass fraction) thereof
100～150 parts of Resins, epoxy
1～50 part of urethane
5～50 parts of cement flours
1～20 part in lime carbonate
Silica 1～15 part
0.2～3 part of silane coupling agent
Wherein: said Resins, epoxy at room temperature is in a liquid state, and silane coupling agent is a Racemic glycidol oxidation oxypropyl trimethyl TMOS, and cement flour is the ordinary Portland cement powder;
Said curing agent component is hexanediamine, diethylenetriamine, quadrol, three [(dimethylamino) methyl] phenol (DMP-30), benzyldimethylamine, Mannich modified amine (T-31) or polymeric amide, or their mixture.
Above-mentioned substance is the commercial goods except that urethane.
The base material component of the said waterproof paint of the present invention is preparation like this:
At first be 1000 PTMG and Toluene-2,4-diisocyanate with molecular weight, the 4-vulcabond is a raw material, become the end capped urethane of isocyano by prior art for preparing, according to the above ratio Resins, epoxy is added then and be equipped with in the reactor of the end capped urethane of isocyano, be heated to 80 ℃ of reactions 30 minutes, in reactor, add cement flour, silicon-dioxide, lime carbonate and silane coupling agent by proportioning at last, get the base material component after stirring.
The using method of the said waterproof paint of the present invention is such:
During use, base material component and curing agent component are mixed in proportion, directly handle on the interface applying with brushing method, get final product through self-vulcanizing in desire.
The said waterproof paint of the present invention have can in infiltration face or water, directly construct and constructional method simple, cohesiveness is strong between coating and the interface, advantage such as the good and environmental pollution of the water permeability resistance of coating is little.
Specific implementation method
The present invention is further illustrated below by embodiment, but it does not influence protection scope of the present invention
Embodiment

At first taking by weighing 120 gram molecular weights and be 1000 PTMG adds and agitator, thermometer and logical nitrogen valve are housed, are connected in 500 milliliters of four-hole reactors of reduced vacuum pump, be heated to 100 ℃, vacuumize dehydration, drip 44 gram Toluene-2,4-diisocyanates when being cooled to 50-55 ℃, the 4-vulcabond, keep reaction discharging in 3-4 hour under the inert atmosphere conditions, it is standby to get required urethane.
The Resins, epoxy of 5 times of weight is added in the reactor that above-mentioned urethane is housed, is heated to 80 ℃ of reactions about 30 minutes, get modified epoxy.Progressively add cement flour, silicon-dioxide, lime carbonate by proportioning in this modified epoxy, it is standby to get matrix component after stirring.
After benzyldimethylamine, Mannich modified amine, polymeric amide, the DMP-30 of said ratio fully mixed curing agent component.
Before the use, two components mix, and apply on the cement plate more than 7 days in being soaked in water with brushing method, and room temperature used up in following 4 hours.Film and solidified the back through 24 hours to test its every performance as follows:
| Film performance | Product property of the present invention | Reference examples |
| Shock strength | 1.74MPa | 1.65MPa |
| The wetted surface cohesive strength | 2.61MPa | ≥0.5MPa* |
