Abstract
The present invention belongs to a light wall brick material consisting of light concrete and inorganic reinforcing fiber. The light concrete consists special type low-alkali concrete 65-90 percent, powder vesicant 0.1-0.5 percent, expanded mineral lightweight aggregate 10-20 percent, and ethylene polymer of water-solubility 1-10 percent, wherein the chemical composition of the special type low-alkali concrete is that SiO2 6-9 percent, Al2O3 11-21 percent, Fe2O3 1-2 percent, CaO 40-45 percent, SO3 13-25 percent, the loss on ignition is 7-11 percent. The production process of the board brick adopts the method of grouping erection dies. The board brick is characterized in light weight, high strength, moisture resistance, water resistance, durability, and appearance formation.
Description
The present invention relates to a kind of partition board, mainly is with extraordinary low alkali cement and powdery blowing agent, and the inorfil of producing with the battery mould pouring forming technology strengthens light porous partition board.
In traditional building many with brick as partition material, but be used in highrise building since brick from great, the structure foundation load-bearing is increased, therefore press for the partition material of lightweight, the light partition wall material of present domestic application has: lightgage steel joist extrusion coating paper surface gypsum board, gypsum perlite hollow lath, the cement perlite filled board, ultralight concrete sandwich plate, Taibai panel, it flourish plate, silicon magnesium aerating plate etc.But gypsum plank and silicon magnesium aerating plate moisture-proof, poor water resistance.Cement perlite filled board and ultralight concrete sandwich plate weight are not as people's will, and the price of Taibai panel and day flourish plate is too expensive again, and the use of light partition wall material is restricted.
The objective of the invention is to develop a kind of partition board.Make its not only intensity height, humidity, water-fast, fire prevention, excellent in durability, and cost is lower.
The present invention at first studies the prescription of partition board, adopt the extraordinary low alkali cement of aquation liquid phase (solid-liquid=1/10) pH value 1 hour＜10.5, reduced the corrosion of cement to fortifying fibre, improved the durability of partition board: add the powdery blowing agent in addition, in forming process, produce a large amount of CABs, reduce the weight of partition board, relatively also reduced cost; Adopt the explained hereafter of battery mould moulding by casting, reduced cost of production, improved production efficiency, the product strength height of producing, flat appearance, the decoration construction of being more convenient for.
Partition board of the present invention adopts battery-mold process production by lightweight concrete and inorganic reinforcing fiber.
The prescription of lightweight concrete of the present invention is:
Extraordinary low alkali cement 65～90%
Powdery blowing agent 0.1～0.5%
Expanded mineral light aggregate 10～20%
Water-soluble ethylene base polymer 1～10%

Partition board production technology of the present invention is: extraordinary low alkali cement, expanded mineral light aggregate, powdery blowing agent are weighed up by proportioning, put into mixer and stir that the back adds the water-soluble ethylene base polymer and water stirs, make the mixture of lightweight concrete, in formwork erection, inorganic reinforcing fiber is arranged, again the lightweight concrete mixture for preparing is injected the formwork erection that assembles, after treating initial set, put into temperature and be 35～50 ℃ environment maintenance form removal in 6 hours, goods rewetting was supported three days, just can be used as finished product.
Adopt extraordinary low alkali cement: the expanded mineral light aggregate: the powdery blowing agent: water-soluble ethylene base polymer=80: 20: 0.4: 5 preparation the present invention (1
#Sample), then with the partition board (2 of common low alkali cement and perlite preparation
#Sample), their physical and mechanical property is relatively as table 1:
Table 1
| Sample number into spectrum | Unevenness | Weight per unit area | Fracture resistence force | Full water fracture resistence force |
