Abstract
The invention discloses an energy-saving and environment-friendly straw brick with a mould-proof and mothproof function and solves the problem that the straw brick is easy to go moldy and damage by worms. The straw brick is characterizes in that: raw materials comprise 100 parts by weight of straws, 5-10 parts by weight of wormseeds, 10-50 parts by weight of citronella and 2-8 parts by weight of elecampane. The result of an experiment research shows that the straw brick prepared according to a formula of the raw materials can effectively reduce moldy and worm damage occurrence rates.
Description
Technical field
The present invention relates to the energy-conserving and environment-protective building material field, be specifically related to a kind of energy-conserving and environment-protective grass brick of anti-mould and anti-moth.
Background technology
Present many small and medium-sized cities and villages and small towns building brick great majority are clay bricks, though clay brick is gathered materials on the spot, cost is low, the technology characteristic of simple, but clay brick expends a large amount of land resourcess and the energy, and has also discharged great amount of carbon dioxide in the process of baking bricks.Since the eighties in 20th century, environment protection and energy-conservation requirement grow to even greater heights, and various countries begin to research and develop the energy-saving building material, also constantly have the energy-saving wall material to come out, but these new wall material investments are big, and the price height is not suitable for the small towns and uses.
So the application of careless brick begins to cause that all circles notice that careless brick as its name suggests, is exactly with careless brickmaking.Careless brick the earliest can be traced back to the nineties in 19th century, and people find that unintentionally packing machine can break into loose agricultural crop straw the big careless piece that can be used for the careless brick of building.In the grassland region Nebraska of northern US, careless brick house is then also being keeped out wind and rain for people so far.In recent years, building a house with careless brick becomes emerging construction industry, is rapid growth trend.Grass resource is abundant, draws materials easily, and cost is low, and is renewable resources, and appropriateness is utilized, in environmentally friendly.Careless brick heat-insulating property has also been done sufficient research both at home and abroad.Tongji University's Heating,Ventilating and Air Conditioning (HVAC) and combustion gas institute have carried out analog calculation to the annual heating energy consumption of Benxi, China Liaoning Province grass brick house, demonstrate good energy conservation characteristic.The innoxious technology transfer center of Chinese environmental tracking and testing shows: at one time, the common brick house of the Energy Efficiency Ratio of careless brick house is high by 68%.The making of present straw building block generally is to put grass into careless brick machine, suppresses into thin slice from level to level, again these thin slices is tied into careless brick.When not needing full brick, can use these thin slices.The density of grass brick is generally every cubic metre about in the of 100 kilograms, and bearing capacity can reach every square metre more than 1900 kilograms.
But the problem that perplexs careless brick just is to go mouldy, and infested.Keep worm's ovum in weeds, agricultural crop straw the inside and the worm pupa can eat in careless brick, and careless brick is in the warm weather that continued for 3 to 4 weeks, then may grow fungi or other microbial growths, and cause that careless brick intensity reduces, efflorescence, decortication, last delamination reduces physical strength, the heat insulation effect deterioration, maintenance intervals shortens.For this reason, adopt organic class pesticide-treated rice straw among the preparation technology who has, but toxicity of pesticide is big, residual quantity is big, can not be used for the building between residential houses.Above defective has caused the application of present careless brick mainly in the north.
Summary of the invention
Technical assignment of the present invention is at above the deficiencies in the prior art, and a kind of energy-conserving and environment-protective grass brick of anti-mould and anti-moth is provided.
The technical scheme that the present invention solves its technical problem is: a kind of energy-conserving and environment-protective grass brick of anti-mould and anti-moth is characterized in that raw material comprises: forage 100 weight parts, Mexican Tea Herb 5 ~ 10 weight parts, lemongrass 10 ~ 50 weight parts, Root of Racemose Inula 2 ~ 8 weight parts.
Above-mentioned raw materials can also comprise: peach gum 1 ~ 5 weight part.
Above-mentioned raw materials can also comprise: fire retardant.
Above-mentioned forage is weeds or stalk.
Wherein, described Mexican Tea Herb is Chenopodiaceae Chenopodium plant Mexican Tea Herb Chenopodium ambrosioides L. herb.Be born near the village and the roadside, also often there is the grower in the north.Be distributed in provinces and regions such as Jiangsu, Zhejiang, Jiangxi, Fujian, Taiwan, Hubei, Hunan, Guangxi, Guangdong, Sichuan and Guizhou.Experiment in vitro: Oil of chenopodium is to the first excitement of acting as of roundworm, and benumb the back, and it is tetanic to produce non-reversibility at last; Trichomonad there are inhibition and killing action; Also effective to uncinariasis.Oil of chenopodium 1:64,000 growth (not being subjected to influencing of serum and cultured continuously, to the skin nonirritant) that can suppress pathogenic dermatophytes at 1:1, has effect to branch bacterium (tuberculosis) concentration more than 000.
Described lemongrass is Gramineae Cymbopogon plant lemongrass Cymbopogon citratus (DC.) Stapf herb.The habitat is distributed in China south China, southwest, Fujian, Taiwan.To being permitted 10 kinds of common pathomycetes such as Lan Shi trichophyton and Mongolian mutation thereof, homocentricity trichophyton, trichophyton in various degree restraining effect is arranged all in vitro.In the external effect that the inhibition paramecium is arranged.In addition, the lignocellulose massfraction of the lemongrass at 10 monthly ages is 62.60%.Lignocellulose proportion is little, specific surface area is big, has excellent insulating, heat insulation, sound insulation, insulation and permeability, and thermal expansion is even.The lemongrass lignocellulose has good snappiness and dispersiveness, mixes the back and forms tridimensional network, has strengthened anchorage force and the resisting power of system, can improve stability, intensity, degree of compactness and the uniformity coefficient of system.
Described Root of Racemose Inula is the dry root of feverfew Root of Racemose Inula Inula helenium L. or Tibet inula root Inula racemosa Hook.f..Ecotope: give birth to moist place such as river bank, Tian Bian.Resource distribution: be distributed in northeast, North China and northwest; In Hebei, there is cultivation on ground such as Shanxi, Zhejiang, Henan, Hubei, Sichuan.Inula camphor and derivative thereof contained in the Root of Racemose Inula volatile oil have anthelmintic action, and external all have restraining effect to tubercule bacillus, dysentery bacterium, streptococcus aureus, Pseudomonas aeruginosa, common pathogenic dermatophytes.
More than three kind of plant, be China's south frequently seen plants, resource extensively is easy to get.Behind the forage manufacturing bricks by mixing, can effectively kill and suppress worm's ovum and fungi in the careless brick, effectively reach the purpose of anti-mould and anti-moth, and do not destroy the antifreeze and solar heat protection ability of careless brick.And smell fragrance, nontoxic in human body, can be used as interior architecture and use.
Described peach gum is made by the secretory product hydrolysis of peach, can play the tackiness agent effect, and because its pure plant component, environmental protection more.
Described fire retardant can be mineral-type fire retardants such as aluminium hydroxide, magnesium hydroxide, zinc borate, weisspiessglanz, also can be organic based flame retardants such as flame-retarded resin, phosphorous acid ester, halogenated phosphate.As long as can stop, delay or stop flame transmission effectively, thereby the material that reaches the fire-retardant effect of careless brick all can add.
