Abstract

The invention discloses light cement granules for a building energy-saving material and a light roof greening framework material and a production method thereof. The light cement granules are formed by wrapping organic or inorganic light materials on cement. The production method for the light cement granules is simple and convenient and does not need high-temperature sintering and complex equipment; and the produced granules have the same function as high-temperature sintered ceramic particles, but have much lower cost than the high-temperature sintered ceramic particles. The light cement granules have wide application, can be made into light modules serving as building materials, and also can be made into the framework material for a light roof greening plant growth base material.

Description

Light cement granules and production method thereof

Technical field:

The present invention and building energy conservation are relevant with the greening material, are a kind of light cement granules and production methods thereof of making energy-saving building materials, can being used for roof greening planting matrix scaffold material of can being used to.

Background technology:

Chinese patent 1 discloses a kind of lytag (patent No. 200710113600, contriver Gao Yuexu), it is characterized in that it selects the carbon content volume ratio for use is that 7% the flyash and the aqueous solution are the masterbatch of lytag, volume ratio is 7% flyash for the carbon content volume ratio: the aqueous solution=99.8%: 0.02%; The aqueous solution is made up of water glass, gelling resin and water, and volume ratio is a water glass: gelling portions of resin water=0.6%: 0.4%: 99%; With the carbon content volume is that 7% the flyash and the aqueous solution fully stir mixed, send into spherical machine system ball after mixing, sphere diameter is 10-20mm, send into again in the uncovered kiln, drawing with faggot, blowing spontaneous combustion with gas blower at kilneye, treat that kiln top coal ash ball burnt be popular in after, turn off the blast, treat kiln discharge after 40 minutes, lytag is promptly made.

Chinese patent 2 discloses a kind of method (patent No. 200710157879 of utilizing filter mud of sugar refinery to produce porous ceramic grain, contriver Zhang Yucang, He Lianfang, Meng Yan), it is characterized in that using by a certain percentage pottery to obtain haydite as raw material through art breading such as filter mud dehydration, batching, system embryo, high temperature sintering moulding with clay, sugar refinery dehydration filter mud, toughener.

The weak point of above-mentioned patent is, the haydite production method that is adopted all needs the high temperature sintering of power consumption power consumption can moulding, and not only production cost height, and technology multiple tracks does not have a locking equipment to be difficult to make.

Summary of the invention:

The objective of the invention is, solve and just can produce light cement granules and production method thereof without high temperature sintering, without complex apparatus, low production cost with the basic identical purposes of haydite.

Specifically:

The production stage of light cement granules is: 2-1 prepares the lightweight material particle, 2-2 sprays to the lightweight material particle and adds water, the 2-3 limit adds the waterside and stirs, 2-4 joins dry cement in the particle with spraying powder method then, the 2-5 limit sprays into the cement flour limit and stirs, making cement flour evenly adhere to particle surface wraps up perlite particle, 2-6 adds fluffy powder again, the limit adds the flyash limit and stirs, make it form not the round shaped grain of adhesion mutually, 2-7 finishes sclerosis back turning, forms the not light cement granules of phase adhesion, and 2-8 packs light cement granules.

This light cement granules structure from outer to inner is the 1-1 fluffy powder, the cement layer of 1-2 parcel, 1-3 lightweight material particle.

Said 1-1 fluffy powder can be flyash, stone flour, earth etc.;

Said 1-2 cement can be for having bought on the market;

Said 1-3 lightweight material particle can be lacunose various mineral and organism, and for example perlite, straw cane, cinder, plastic foam, branch also can be made broken lightweight material of washing one's hair shape particle and use.

Description of drawings:

Fig. 1 is the structural representation of light cement granules of the present invention.

Among the figure: 1-1 fluffy powder, the cement layer of 1-2 parcel, 1-3 lightweight material particle.

Fig. 2 is the method synoptic diagram of light cement granules embodiment 3 of the present invention.

Among the figure: 2-1 prepares particle, and 2-2 adds water, and 2-3 stirs, and 2-4 spraying cement, 2-5 wrap grain, and 2-6 adds fluffy powder, 2-7 sclerosis, 2-8 packing.

Embodiment:

Embodiment 1

Perlite particle is carried out sub-sieve, be divided into different size by diameter, taking shelter from rain respectively, it is standby to stack.

The perlite particle of same specification is put into the container of smooth inner wall, particle sprayed add water, the limit adds the waterside and stirs, then dry cement is joined in the particle with spraying powder method, the limit sprays into the cement flour limit and stirs, and makes cement flour evenly adhere to particle surface perlite particle is wrapped up, add dry powder coal ash (also can use drystone powder etc.) again, the limit adds the flyash limit stirs, and makes it form not the round shaped grain of adhesion mutually, round shaped grain is emitted to stack from container harden.At this moment turning after sclerosis is finished forms the not light cement granules of phase adhesion.

Embodiment 2

The straw cane is cut into straw stem particle with cane diameter equal length, and taking shelter from rain, it is standby to stack.

Straw stem particle is piled heap on concrete floor, straw stem particle sprayed add water, the limit adds the waterside and stirs, then dry cement powder is joined in the straw stem particle, the limit adds the cement flour limit stirs, and makes cement flour evenly adhere to straw stem particle surface particle is wrapped up the formation round shaped grain, adds dried earth powder (earth requires the immature soil of table soil below 10 centimetres) again, the limit adds dried earth powder limit stirs, till not adhering mutually to particle.Put the granulation mass that newly forms into the row sclerosis.At this moment turning after sclerosis is finished forms the not light cement granules of phase adhesion.

Embodiment 3

The peat composed of rotten mosses of broken powder is pressed into particle, peat composed of rotten mosses particle sprayed add water, the limit adds the waterside and stirs, dry cement powder is joined in the peat composed of rotten mosses particle rapidly then, the limit adds the cement flour limit stirs, and makes cement flour evenly adhere to the peat composed of rotten mosses particle surface particle is wrapped up the formation round shaped grain, adds dried earth powder (earth requires the immature soil of table soil below 10 centimetres) again, the limit adds dried earth powder limit stirs, till not adhering mutually to particle.Put the granulation mass that newly forms into the row sclerosis.At this moment turning after sclerosis is finished forms the not light cement granules of phase adhesion.

In sum, advantage of the present invention is:

1. do not need high temperature sintering and complex apparatus just can produce light cement granules;

2. more much lower than the haydite cost of high temperature sintering;

3. of many uses. Can make lightweight modules as construction material with the light cement granules that various light-duty mineral materials are made. The light cement granules made from the organic matter lightweight material can be used as the framework material of light roof greening. Lacunose various mineral and, for example perlite, straw cane, cinder, plastic foam, branch also can brokenly be washed one's hair the lightweight material granulation use of shape.

In a word, the present invention can be without the high temperature sintering method, and without complex apparatus, the method for producing light-duty particle is easy, low production cost, institute's invention light cement granules of many uses.
