Abstract
The present invention provides a kind of building material with stalk as main material and its production process. The building material is produced with stalk powder, light burnt powder, glass fiber, halide powder solution, ferric alum, Gelaihan salt, sodium phosphate hydrate, calcium carbonate, oxalic acid, and magnesium hydroxide. It has high stalk utilization, low cost and simple production process, and may be used as light building material for wall, ceiling, column, window and door pocket, etc.
Description
Technical field
The present invention relates to a kind of material of construction that stalk makes and preparation method thereof that mainly utilizes.
Background technology
Over the past thousands of years, people take clay in a large number and fire solid brick or the hollow brick materials for wall as house and all kinds of buildingss.Bake bricks owing to cut the earth year after year, damaged a large amount of arable lands, seriously destroyed human non-renewable land resources of depending on for existence.The fuel of baking bricks simultaneously is mainly coal,, cost big except that usage quantity is high, the more important thing is and causes environmental pollution.In addition, most of peasant is not that to sell the paper mill be exactly to burn on the spot to the processing of stalk, causes great waste, makes atmosphere be subjected to severe contamination, has both influenced normally travelling of automobile, aircraft, also easy initiation fire.Some enterprises or individual seek to utilize and add some tackiness agents and matrix material etc. after the crushed stalk of farm crop and make light wall materials to replace the use of brick in recent years, both make utilization of waste material, saved soil and coal resources, reduced cost as Chinese patent 91109899,87103594,99115722,01108764, and can alleviate the weight of buildings own again.But these material ubiquity straw utilizations of making low (account for product weight 10%), toxicity is big, scent of, from great, deficiencies such as cost is high, toughness and intensity difference, and waterproof, fire prevention, anti-ly tear open, anti acid alkali performance can be lower
Summary of the invention
The technical problem to be solved in the present invention is the defective that exists in the prior art for overcoming, and a kind of material of construction that stalk makes and preparation method thereof that mainly utilizes is provided, it should have, and nontoxic, pollution-free, odorlessness, straw utilization rate height, every index meet that national standard, cost are low, fire prevention, waterproof, insect protected is stayed, preserving period is short characteristic.
Technical solutions according to the invention are: this material is formulated by following composition:
Straw powder 11-20kg
Light burnt powder 11-18kg
Glass fibre 2-4kg
Halogen powder in the halogen powder solution: water is 0.45-0.9: 1
Contain in the anti-halogen recombiner: siderotil 0.5-2%
Lattice come Han Shi salt 0.5-2%
Ten phosphate dihydrate sodium 1-2%
Contain in the anticorrosion recombiner: lime carbonate 1-2%
Oxalic acid 0.5-2%
Magnesium hydroxide 0.5-2%
Halogen powder solution in the mixing solutions that is mixed with by halogen powder solution, anti-halogen recombiner and anticorrosion recombiner: anti-halogen recombiner is 1000: 6-10; Halogen powder solution: anticorrosion recombiner is 1000: 6.5-9.5.
This preparation methods is should successively anti-halogen recombiner and anticorrosion recombiner be added respectively in the halogen powder solution according to quantity when the preparation mixing solutions.
Agricultural crop straw has taken bigger ratio among the present invention, and the utilization ratio of stalk is improved significantly, more can reduce the cost of product.Straw powder is equipped with pumice powder and, can be made into as material of construction and finishing materials such as light cellular partition board, top ceiling, wall skirt plate, three anti-plates, FRP Columns, external window sleeve, internal door pockets with mixing solutions and the closely knit moulding of fiberglass gridding cloth by halogen powder solution, anti-halogen recombiner, the preparation of anticorrosion recombiner.Under the situation with volume, the weight of making product with this material is 33kg/m
2, have only 1/6. of fragment of brick to detect through national building materials industry wall roofing quality of materials supervision and inspection center, area density is 44kg/m
2, the drying shrinkage value is 0.6mm/m, and fracture resistence force is 4809N, and it is qualified that the test of shock resistance, single-point hanging force is.Simultaneously, this material fire endurance is greater than 4 hours, the rapid heat cycle no change, and sound-damping qualities is greater than 51dB, soaks 48 hours sample no changes, the acid-and base-resisting better performances respectively in 5% HCL solution and 5-15%NaoH solution.This material also have fire prevention, waterproof, insect protected, non-foaming, do not ftracture, do not get damp, characteristic such as modification, "dead", nontoxic, odorlessness, pollution-free, high strength, high tenacity not.Because it is big that stalk reclaims usage quantity, every mu of stalk can be increasing peasant income 60-100 unit, and refuse is made full use of, and turns waste into wealth.
Embodiment
Be example all to make one square metre of Light trabs (33Kg) material requested
Embodiment 1:
1, preparation halogen powder solution: when envrionment temperature is 5-10 ℃, add 900kg halogen powder in 1000kg water, stirring is stand-by after it is fully dissolved.
2, preparation mixing solutions: add the anti-halogen recombiner of 8kg in aqueous salt brine, the anticorrosion recombiner that adds 8kg after the stirring and dissolving again is stand-by.
3, take by weighing 11kg straw powder (70-80 order) and 18kg light burnt powder and pour the mixing solutions that injects 1.9 times of weight behind the stirrer mixing into, stir into solvent or diluent.
4, according to quantity the layering of 4kg fiberglass gridding cloth is arranged net after solvent or diluent being injected the formwork erection machine, and by the bonding closely knit moulding sclerosis of solvent or diluent, one week of maintenance is finished product.
Embodiment 2:
1, preparation halogen powder solution: when envrionment temperature is 10-20 ℃, add 500kg halogen powder in 1000kg water, stirring is stand-by after it is fully dissolved.
