Abstract

The invention discloses a straw light-weight energy-saving insulated building block and a method for producing the same. The method comprises the following steps: using broken straw segments processed by a surface modifier, high strength low-alkali cement, fly ash, superfine active mixed materials and the like as main raw materials; adding various additives such as a waterproof impermeable agent, a preservative, a high-efficiency water reducing agent, an excitant and the like and modified materials to the main raw materials, mixing all the materials evenly, and adding water to the mixture and blending the mixture evenly; molding, demolding and maintaining the mixture to mold the building block (a reinforcing rib of which the surface is provided with a plurality of transverse lug bosses), and coating cement waterproof fluid on the outside; and making protection layers on two sides of the building block with ordinary Portland cement, sand, slag, additives and water so as to obtain the straw light-weight energy-saving insulated building block. The straw light-weight energy-saving insulated building block has the characteristics of light weight, high strength, good thermal insulation property, low water absorption rate, high freeze-melt resistance, fire prevention, water prevention, seepage prevention, insect and mouse damage prevention and the like, and saves 50 percent of energy for a single wall body material in the northern cold areas. Besides, the straw light-weight energy-saving insulated building block can be widely popularized and applied to the field of construction, in particular to the village and small town dwelling constructions in the northern cold areas.

Description

Stalk light body energy-saving heat preserving building blocks and manufacture method thereof

Technical field:

The present invention utilizes agricultural wastes such as stalk to make northern country dwelling house light heat insulation construction material, discloses a kind of stalk light body energy-saving heat preserving building blocks, also discloses the manufacture method of this building block simultaneously, belongs to the energy-saving building materials production technical field.

Background technology:

At present, China has in nearly 40,000,000,000 square metres of urban and rural buildings, and 99% belongs to high energy consumption building, and annual also with the trend development of hundred million square metres of 15--20.Expect the year two thousand twenty, urban and urual areas of whole country's building area will increase 30,000,000,000 square metres newly, and building energy consumption will reach 10.9 hundred million tons of standard coals, and the energy consumption of unit building area is more than three times of developed country.Because coal heating, causing northern China part City Air Pollution Index is two to five times of highest standard of world health organisation recommendations.26,000,000,000 m are arranged in China's existing building at present ²In the rural area, according to statistics, following 10 are only the rural development dwelling house just will reach 6,000,000,000 m ², the dwelling house that wherein is located in severe cold, cold and Xia Redong cryogenic region will reach 5,000,000,000 m ²

China's building energy conservation system mainly contains at present: polystyrene block (EPS) approaches plastoring system, extruded polystyrene board (XPS) approaches plastoring system, ZL adhesive powder-polystyrene granule thermal insulation mortar plastoring system, polystyrene block concrete shear force wall cast in situs system, the gas concrete self-insulation system, the mineral wool board outer heat preservation system, the polyurethane external wall heat insulation system, steel wire net rack polyphenyl plate cast-in-place concrete system, Foamglas foam glass external thermal insulation system, polyurethane thermal insulation system, R.E (rare earth) composite wall insulative materials technology etc.But cost an arm and a leg, be difficult in village-town house, promote the use of.The northern China severe cold area utilizes single materials for wall to do to go along with sb. to guard him, bearing wall reaches 50% energy-saving effect does not also have.

Summary of the invention:

The present invention utilizes agricultural wastes such as stalk to make northern country dwelling house light heat insulation construction material, discloses a kind of stalk light body energy-saving heat preserving building blocks, also discloses the manufacture method of this building block simultaneously.

The concrete prescription of stalk light body energy-saving heat preserving building blocks of the present invention following (by ratio of weight and the number of copies):

High-strength low alkali cement 1, flyash 0.05～1, superfine active mixed material: 0～0.2, section crushing straw (the homemade low formaldehyde content modification PVFM latex surface modifier of surface spraying) 0.1～1, high molecular polymer 0～0.1, waterproof anti-permeability agent 0.005～0.05, anticorrisive agent 0.001～0.1, high efficiency water reducing agent 0.005～0.01, exciting agent 0～0.05, water 0.035～1.

Behind the block forming (external surface has the ribs of some lateral projection), the waterproof of cementing outward liquid, both sides are topping (also can) with Portland cement, sand, slag and Admixture.

Described high molecular polymer is selected a kind of of acrylic acid system emulsion, ethylene-vinyl acetate copolymer, benzene emulsion, polyethenol series latex, pollopas etc. for use or is mixed.

Technical solution of the present invention is as follows: at first, it is stand-by to take by weighing raw material according to the above ratio;

After mixing various Admixtures such as high-strength low alkali cement, flyash, superfine active mixed material, waterproof anti-permeability agent, anticorrisive agent, high efficiency water reducing agent, exciting agent and material modified mixing in proportion; mix with the section crushing straw of handling through surface modifier; add the water uniform mixing; through moulding, the demoulding, maintenance; behind the block forming (external surface has the ribs of some lateral projection); the waterproof of cementing outward liquid, topping (also can) is made with Portland cement, sand, slag and Admixture and water in both sides.Promptly get stalk light body energy-saving heat preserving building blocks of the present invention.

Good effect of the present invention is, this building block has lightweight, high-strength, good heat insulating, characteristics such as water absorption rate is low, freezing and thawing performance is high, fire prevention, waterproof, antiseepage, the insect protected plague of rats, has realized at the single materials for wall of north cold area energy-conservation 50%.And utilized agricultural wastes resources such as stalk, and protected environment, with low cost; compare with like product and to have tangible technical advantage and economic advantages; be particularly suitable for the northern country dwelling house, can in building field, be extensive use of, will produce huge economic benefit and social benefit.
