Abstract

The present invention relates to a method for manufacturing building walls, which uses rice hulls as main raw material. The method mainly comprises that pulverized rice hull flour with 40 to 60 meshes is soaked by a coagulation accelerator with the concentration of 0.5 to 2%, extruded and formed after being thoroughly mixed with film-forming additives with certain proportion, plasticizing agents, waterproof agents, flame retardant, dispersing agents and foaming agents; the wall has the performance of water prevention, fire prevention and heat preservation through the techniques of solidification, natural maintenance, etc., has the advantages of light self weight, convenient construction and low manufacture cost and is a novel environmental protection building material with waste utilizing, energy saving, land saving and wall reform trend conformity.

Description

A kind of manufacture method of construction wall

The present invention relates to a kind of is the manufacture method of the construction wall of major ingredient with the husk.

Even to this day, " Qin brick and Han tile " is still the main material of construction of buildings, its manufacturing be with destroy environment, energy loss is a cost.In recent years various novel environment friendly building materials are come out one after another, and strengthen batten, " GRC " cement, flyash enhancing batten etc. as paper straw board, Paper-faced gyp.The said products energy-conservation, save land, aspects such as sharp useless, environmental protection, promotion wall reform perform meritorious deeds never to be obliterated, but have some defectives on some performances.Strengthen batten unsatisfactory on intensity and the water resistance as Paper-faced gyp: the secondary treatment of then on waterproof, fire resistance, still needing of paper straw board, and cost is higher, brings certain difficulty to penetration and promotion; " GRC " cement, flyash batten height of then conducting oneself with dignity is made troubles to installation, and flyash contains certain harmful radioactive element, also remains on the thermal and insulating performance further to be improved.

The purpose of this invention is to provide a kind of waterproof, fire prevention, intensity height, from heavy and light, cost low be the manufacture method of the novel environment friendly construction wall of major ingredient with the husk.

Technical scheme of the present invention is as follows:

Chaff powder is broken to 40～60 orders, the concentration that is blended into 15～25% (weight ratios) is 0.5～2% setting accelerator, stirred 5～8 minutes, shelved 15～20 hours, add film coalescence aid water glass, fire retardant, water-resisting agent oxalic acid, softening agent, dispersion agent and whipping agent more therein, fully stir after 7～10 minutes, with the glass fiber reticular cloth extrusion molding of surface through the propylene glycol processing, solidified between 55～58 ℃ of isothermal curings 16～24 hours, last natural curing was the finished product body of wall in 12～15 days again.

Chaff powder: setting accelerator: film coalescence aid: fire retardant: water-resisting agent: softening agent: dispersion agent: whipping agent=52～65: 0.5～2: 10～17: 0.3～0.815～35: 0.2～0.8: 0.2～0.5: 0.2～1.2.

Setting accelerator can be Sodium Fluoride, vitriolate of tartar or ammonium sulfate, fire retardant can be coarse whiting or fine particle calcium carbonate, softening agent can be methylcellulose gum or Xylo-Mucine, and dispersion agent can be Sodium hexametaphosphate 99 or tertiary sodium phosphate, and whipping agent can be sulfonation ether or sodium abietate.

Extrusion machine pressure is 12～15MPa, compression ratio 1: 2.5.

The present invention has following advantage: 1, sharp useless environmental protection, energy-conservation, save land.2, product has waterproof, fire prevention and thermal and insulating performance.3, from heavy and light (38kg～42kg/ square metre).Because major ingredient is a husk, and the content height, the deadweight that has alleviated body of wall so greatly only is 1/4～1/6 of a solid clay brick, can reduce the building foundation section relatively thus, the sectional area of the degree of depth and beam column and the ratio of reinforcement, thereby the comprehensive cost of reduction buildings.4, product can be made the porous batten of plurality of specifications such as 2500 * 600 * 90mm, easy construction, separates flexibly.The wet trade more than 50% be can reduce simultaneously, work efficiency and construction speed improved.5, compare with solid clay brick, identical floor area of building can improve the usable floor area about 5%.6, cost is low.Husk almost is a waste, does not need binding agent again, and every construction cost per square meter only is 45～52 yuan, and the solid clay brick wall reaches 54.7 yuan (above-mentioned prices all refer to install whitewash).

Accompanying drawing is a craft block-diagram of the present invention.

Below provide embodiments of the invention:

1, chaff powder is broken into 40～60 purpose chaff powders, in closed pipeline worm conveyor input soaking and stirring container, be blended into 15～25% concentration and be 0.5% fluoridize and receive solution, starting stirrer stirred 5～8 minutes, shelve after 15～20 hours and deliver in another stirred vessel with worm conveyor, in chaff powder: fluoridize and receive: sodium silicate: methylcellulose gum: coarse whiting: oxalic acid: Sodium hexametaphosphate 99: sulfonation ether=52: 0.5: 10: 0.3: 35: 0.8: behind 0.2: 1.2 the ratio thorough mixing, feed extrusion jolt moulded machine continuously with worm conveyor, the glass fiber reticular cloth that handle through propylene glycol on the follow-up surface in extrusion process, extrusion pressure is 12～15MPa, compression ratio is 1: 2.5, deliver to by apron conveyor through the batten of extrusion molding and to solidify 16～24 hours between curing, constant temperature is 55～58 ℃ between curing, and natural curing was the finished product body of wall in 12～15 days then.
