Abstract
The invention discloses a novel mortar concrete water-proof agent. The novel mortar concrete water-proof agent comprises, by weight, 5-15 parts of straw powder, 15-25 parts of coal ash, 2-5 parts of water reducing agent, 2-10 parts of alum, 5-10 parts of gelatin, 2-10 parts of potassium dichromate, 5-15 parts of silica fume and 1-2 parts of air entraining agent. Compared with the prior art, the actual use effect of the mortar concrete water-proof agent is quite good, the waterproof performance of mortar concrete can be remarkably improved, the durability of the mortar concrete is improved, and the service life of the mortar concrete is prolonged.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of new type mortar concrete waterproofer.
Background technology
Mortar concrete waterproofing agent is a kind of chemical admixture, is added in mortar concrete, and when concrete coagulation hardens, volumetric expansion thereupon, plays compensate for shrinkage and tension reinforcing steel bar produces prestress and abundant filling concrete gap.Mortar concrete waterproofing agent is applied to almost in civil construction project used, and be absolutely necessary a kind of additive.But the mortar concrete waterproofing agent sold on the market at present often in actual use, also exists the problem of poor effect.Therefore, a kind of mortar concrete waterproofing agent of highly effective is that society needed badly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new type mortar concrete waterproofer, to solve the problem of currently available products poor effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of new type mortar concrete waterproofer, it comprises the component of following parts by weight:
Wherein, the component of parts by weight is preferably as follows:
Wherein, described stalk powder preferably wheat stalk powder or maize straw powder; Wherein, the particle diameter of stalk powder is 20 ~ 30 μm.
Wherein, described water reducer lignin sulfonate water reducer, Ppolynuclear aromatic salt water reducer or water soluble resin Sulfonates water reducer.
Wherein, the preferred lignin sulfonate water reducer of described water reducer.
Wherein, described air entrapment agent is rosin tree lipid air entrapment agent or fatty alcohol sulfonate class air entrapment agent.
The preparation method of above-mentioned mortar concrete waterproofing agent, it comprises the steps:
(1) by soluble in water to stalk powder, alum, potassium bichromate and gelatin, filter after boiling 1 ~ 2h at 100 DEG C, get solid part;
(2) by the solid part of gained in step (1) and flyash mixing, after reacting 0.5 ~ 1h at 300 ~ 350 DEG C, add water reducer, at 200 ~ 300 DEG C, react 20min;
(3) by after the mixed system of gained in step (2) and SILICA FUME mixing, then air entrapment agent is added, after mixing and get final product.
Beneficial effect:
Compared with prior art, new type mortar concrete waterproofer practical effect of the present invention is splendid, can significantly improve the water resistance of mortar concrete, improve its wearing quality and work-ing life.
