The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the process flow sheet of rice husk thermal insulation porous building-brick;
Fig. 2 is the main TV structure schematic diagram of the preferred embodiment of rice husk thermal insulation porous building-brick.
Embodiment
As shown in Figure 1, a kind of preparation method of rice husk thermal insulation porous building-brick, its step is as follows: a, preparation raw material: be by weight ratio: cement 1000, modification rice husk 264, glass staple fibre 4.4, glue 30, hydrophobic auxiliary agent 4 and water 514; B, by the water diluted for use of the glue of above-mentioned metering and 1:1 mass ratio; C, by the water diluted for use of hydrophobic auxiliary agent and the 1:10 mass ratio of above-mentioned metering; D, remaining water, modification rice husk and glass staple fibre are added in mixing equipment and are uniformly mixed simultaneously, fully wetting modification rice husk; E, the cement of above-mentioned metering is added in mixing equipment and stirred, abundant mixing stirring; F, the glue of thin up in step b is added in mixing equipment and stirred, abundant mixing stirring; G, the hydrophobic auxiliary agent of thin up in step c is added in mixing equipment and to stir 10 minutes, abundant mixing stirring; H, the mixture be stirred divided successively to exert pressure for three times add die for molding, forming pressure >=3.5MPa or >=5MPa, the preferred 3.5MPa of this case or 5MPa; After i, depanning under 60 ℃ of water vapor atmosphere tunnel flowing water 8 hours.
Embodiment mono-:
The density of described modification rice husk is 115～125g/L, and this case preferred density is 120g/L.
Former rice husk/modification rice husk=0.79
The length of described glass staple fibre is 20～30mm.
Modification rice husk addition in walling unit is set: 2.2L/kg cement (cement of 1kg is joined the rice husk of 2.2L)
The setting of rice husk thermal insulation porous building-brick basic components:
Taking 1000g cement is example, and the calculation formula of the weight of water is as follows:
1000g(cement) * 0.17=170g
2.2L(the modification rice husk) * 0.17 * 1000g/L(water-mass density)-30g(glue quality)=344g
Weight=the 170g+344g=514g of water
Wherein 0.17 is constant, and while being convenient in balance formula that cement and modification rice husk change, amount of water calculates, under the environment that to be applicable to forming pressure be 5MPa.When environment that moulding pressure is 3.5MPa, constant becomes 0.18.This constant is finely tuned slightly due to the difference in season and the difference of envrionment temperature.
