Abstract
The invention belongs to the technical field of building materials, and particularly relates to a bubble shrinking agent for foamed cement. The bubble shrinking agent for the foamed cement is prepared from cellulose ether and an anionic surfactant, and the mass ratio of cellulose ether to the anionic surfactant is 1:(1-3). When the bubble shrinking agent is used, the mass ratio of the bubble shrinking agent to the foamed cement is (0.05-1):100. By means of the bubble shrinking agent for the foamed cement, setting of the foamed cement can be fast, the foaming size can be even, the water absorption rate can be lowered, and the later strength loss is small. By means of the bubble shrinking agent, the foamed cement is short in demolding time, and mold collapse is not likely to happen. According to the bubble shrinking agent for the foamed cement, the water absorption rate of the foamed cement can be lowered, and the later strength loss of the foamed cement is small.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of contracting infusion for foam cement specifically.
Background technology
Cement board belongs to non-fire material, nontoxic, environmental protection, low-carbon (LC) are a kind of type materials that country advocates energetically, and its fire resistance reaches A1 level.This product ultimate compression strength high (with plastic foam ratio), thermal conductivity are low, firm with concrete bonding, and the coefficient of expansion is consistent, and working life is consistent with buildings; It is mainly used in roofing thermal-insulating board, inside and outside wall thermal insulation plate, and bonding mortar directly uses sand-cement slurry bonding, makes external wall insulation and is coated with charge level, directly can do protective layer with waterproof anti-crack mortar and glass fiber reticular cloth.During sticking brick, steel wire grid can be hung and can beat plastic anchor bolt, smear anticracking grout sticking brick outward.
Cement board main raw is cement, adds the stirring such as hydrogen peroxide, hard calcium, flyash and cement blowing agent fusion foaming and forms.But when cement board is produced, easily occur that foaming bubble is large, foam uneven problem, make that foaming is coarse, later strength declines, water-intake rate is high.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
For the deficiencies in the prior art, the invention provides and a kind of contracting infusion for foam cement is provided, the size of bubble and the uneven problem that foams can be reduced, make foaming fine and smooth and intensity, reduction water-intake rate can be promoted.
Technical scheme provided by the invention is:
For a contracting infusion for foam cement, it is made up of ether of cellulose and aniorfic surfactant.
As preferably, described ether of cellulose and the mass ratio of aniorfic surfactant are 1:1-3.
As preferably, described ether of cellulose is methylcellulose gum or Vltra tears.
As preferably, described aniorfic surfactant is sodium lauryl sulfate, stearic acid or Sodium dodecylbenzene sulfonate.
Present invention also offers the using method of the described contracting infusion for foam cement, in use, the mass ratio of itself and foam cement is 0.05-1:100 to described contracting infusion.
Compared with prior art, the present invention has following beneficial effect:
(1) the contracting infusion for foam cement of the present invention can make foam cement solidify soon, the size that foams evenly, and can reduce water-intake rate, later strength loss is few.
(2) contracting infusion of the present invention can make foam cement demould time short, and not easily collapse mould.
(3) the contracting infusion for foam cement of the present invention can reduce foam cement water-intake rate, less to its later stage loss of strength.
