Abstract

The invention discloses a water-permeable water-holding brick. The water-permeable water-holding brick is prepared from the following ingredients in percentage by weight: 5-15% of cement, 70-95% of aggregate chips, 0.2-0.8% of a water-permeable water-holding gelling agent, 0.5-1.5% of a coloring and dispersing agent, and 10-25% of water. A preparation method of the water-permeable water-holding brick comprises the following steps: a. preparing an ordinary brick press; b. preparing the aggregate chips and the concrete in advance, stirring the aggregate chips and the concrete for 1 minute to be mixed uniformly, preparing the measured water-permeable water-holding gelling agent and water according to the ratio, injecting the mixture into a stirrer to be stirred for 3 minutes, and performing compression molding, demolding and stacking by the brick press; c. naturally curing the brick subjected to demolding for 7 days, so as to obtain the water-permeable water-holding brick. The water-permeable water-holding brick is not required to be kilned, so that the energy conservation and emission reduction effects are obvious, the manufacturing cost is low, and no secondary pollution is generated; the brick is naturally cured for 7 days after demolding and stacking by the brick press, and then leave the factory; the forms of the brick can be changed randomly, and all needed is to adopt different molds.

Description

A kind of water-permeable and water retention brick and preparation method thereof

Technical field

The present invention relates to a kind of water-permeable and water retention brick and preparation method thereof.

Background technology

The research application of water-permeable and water retention brick starts from the Japan of the seventies in last century before more than 100 year, the problems such as setting of ground are caused because of groundwater abstraction in order to solve this country, propose " the underground also Original Policy of rainwater ", start to develop and permeablely the compacting fragment of brick (being commonly called as magic brick) of water conservation can carry out mating formation of pavement and light carriageway surfacing again containing fine aggregate, the development of 40 years, the urban air-quality of Japan makes great progress.

Make a general survey of China, the ground on the square, commercial street, walkway, community activity ground, parking lot etc. in current China city is mainly laid by the material of the waterproof water conservations such as grouan, marble, ornamental brick, cement and pitch, and faced by the ground of waterproof water conservation, the harm of urban environment is very large.When raining, waterproof water conservation ground prevents rainwater and is directly stored in brick body and is permeated the ground by unnecessary water, and during the rainy day, completely ponding makes the trip of people become very inconvenient; Valuable water resources finally by sunlight and evaporates or flow away with drainage pipeline, has increased the weight of the burden water pollution of municipal drainage facility; A large amount of losses of rainwater cause ground water table to be difficult to go up, and make the ground flora in city be difficult to normal growth, increase the weight of municipal administration greening burden; A large amount of losses of rainwater increase the weight of the generation of the arid in city, lack of water and urban heat land effect further.

China's some water-permeable brick main raw materials in the market adopt pottery or common pervious concrete brick, ceramic water-permeable brick needs to adopt a large amount of kaolin resources, the exploitation of raw material causes the destruction to environment, ceramic mould water-permeable brick complex manufacturing, and ceramic base brick needs the energy of at substantial when forming and sintering, cost is high, and production efficiency is low, Environmental Inputs is large, and one-time investment scale is large, although concrete permeable brick cost is low, but existing concrete permeable brick is due to the particle on surface thick (general backbone grain distributing is 3mm-6mm), although the macrovoid of abutment surface is permeable, voidage is more than 20%, permeable effect can be reached, but effect permeable after first water conservation can not be reached, because the space of brick is large, reduce the cohesive force between macrobead, resistance to compression and folding strength lower and surperficially easily to be blocked by dust, therefore can not continue to keep long-acting water permeability, and the grouan of pavement laying at present, marble is then laid cost height and is not easily oozed dirt, if be stained with spot to be not easy cleaning, affect attractive in appearance, and although ornamental brick contamination resistance is good, but it is not anti-skidding, especially in rainy day or snow sky, danger is caused because of road surface slippery situation, existing water-permeable brick is not adopted by market in a large number due to technologic defect.

In fact, water-permeable and water retention brick has good economic benefit and ecological environment benefit, therefore market is needed a kind of water-permeable and water retention brick of superior performance badly.

Summary of the invention

For above-mentioned technical problem, the present invention discloses a kind of water-permeable and water retention brick, comprises following weight fraction than component: the water of the water-permeable and water retention jelling agent of the cement of 5-15%, the aggregate chips of 70-95%, 0.2-0.8%, the color dispersion agent of 0.5-1.5%, 10-25%.

Preferably, described weight fraction than component is: the cement of 10%, the aggregate chips of 88.5%, 0.5% water-permeable and water retention jelling agent, the color dispersion agent of 1%, the water of 20%.

Water-permeable and water retention brick of the present invention, its preparation method comprises the following steps:

A, prepare common brick press;

B, aggregate chips, cement is pre-configured, stir 1 minute, make it mix; Then the water-permeable and water retention jelling agent measured and water are prepared in proportion; Then inject in stirrer and stir 3 minutes, by brick press compression moulding, the demoulding, pile;

Fragment of brick natural curing after c, the demoulding 7 days, obtains described water-permeable and water retention brick.

The invention has the beneficial effects as follows: described water-permeable and water retention brick does not need klining, effects of energy saving and emission reduction is remarkable, and cost of manufacture is cheap and economic results in society remarkable, and technological design is reasonable, simple for production, does not produce secondary pollution; The quality of brick exceedes current national standard; The production duration is short, and after brick press demoulding pile, natural curing can be dispatched from the factory after 7 days, and brick can arbitrarily change, and only need adopt different mould.

 

Embodiment

The present invention is described in further detail below, can implement according to this with reference to specification sheets word to make those skilled in the art.
