Description
Technical field
The present invention relates to building material field, and in particular to a kind of careless brick of expelling parasite environmental protection.
Background technology
Since 1980s, environmental protection and power conservation requirement are grown to even greater heights, and the Building Heat of careless brick is risen in the whole world.It is beautiful
The ground such as state, Canada, Germany, Britain, Australia come into vogue, large-scale popularization application.In recent years, being built a house with careless brick has turned into
Emerging construction industry, in rapid growth trend.From 1999, linked groups of China cooperated with international body, in northern China
Rural area comes into effect " energy-conservation careless brick build a house capacity building and demonstration project ".In the past few years, the ground of 5 province of northern China 9, which is built together, saves grass
616 sets and 3 primary schools of brick demonstration house owed by a citizen, it is deep to be liked by the vast farmerses masses.By detection, careless brick house is saved up to more than 50%.
People are referred to as " not only original but also efficient, both tradition presented generation again ".
From the point of view of the whole nation, many small and medium-sized cities and villages and small towns still largely use clay brick, although clay brick expends a large amount of soils
Resource and the energy.To find out its cause, one is that the investment of some new wall materials is big, price is high；Two be that clay brick is gathered materials on the spot, and cost is low,
Technology is simple.Want thoroughly to replace clay brick it is necessary to find aboundresources same with clay, materials are easy, and cost is low, again meets
The material of energy-saving and environmental protection requirement.Remaining cane after the universal rice cultivation of south China, paddy rice shelling, is commonly called as straw, not yet
It is fully used.Also there are a large amount of meadows in the north.Grass is renewable resource, appropriate utilization, in environmentally friendly.But, careless brick is deposited
Subject matter be to go mouldy infested, might have a large amount of worm's ovums and worm pupa in weeds, stalk, same day hot air heating and when, just
Meeting breed bacteria, the growth of microorganism so that careless brick efflorescence, decortication, mechanical strength reduction, heat insulation effect reduction are thus needed
Study the problem of composition and preparation technology of careless brick are to solve insect pest.
The content of the invention
For the defect of prior art, it is an object of the invention to provide a kind of careless brick of expelling parasite environmental protection, by adding a variety of drives
The cordyceps sinensis of worm, and preparation method is improved, being capable of efficiently Anti-moth-eating, and environment-protecting and non-poisonous.
The present invention solves technical problem and adopted the following technical scheme that：
The invention provides a kind of careless brick of expelling parasite environmental protection, include the raw material of following parts by weight：Careless slag 30-50 parts, crushed straw aggregate 10-
20 parts, 15-25 parts of granules of polystyrene, 3-12 parts of lavender, 2-6 parts of expelling parasite grass, 1-5 parts of lemongrass, 10-18 parts of water, polypropylene
15-30 parts of acid esters emulsion.
Preferably, the raw material of following parts by weight is included：Careless 40 parts of slag, 15 parts of crushed straw aggregate, 20 parts of granules of polystyrene, smoke
8 parts of clothing grass, 5 parts of expelling parasite grass, 3 parts of lemongrass, 12 parts of water, 20 parts of polyacrylate dispersion.
Preferably, the careless slag is one or both of straw slag, glycyrrhiza extract.
Preferably, the crushed straw aggregate be cotton stalk particle, wheat stalk particle, one kind in rice straw particle or
Two or more combinations.
A kind of preparation method of the above-mentioned careless brick of expelling parasite environmental protection, comprises the following steps：
1）By careless slag, crushed straw aggregate, lavender, expelling parasite grass, lemongrass according to proportioning co-grinding, 60-80 mesh sieves are crossed, are obtained
Grain；
2）By step 1）Obtained particle is mixed to form siccative with granules of polystyrene, and then adding water stirs, and forms wet mixing
Material is closed, polyacrylate dispersion is added, stirred 30-40 minutes at 30-40 DEG C；
3）By step 2）The careless bricks die of compound injection in, be pressed into idiosome under 60-80 DEG C, 2-3MPa pressure；
4）The idiosome is placed at open air drying and conserved 3-5 days, uniform fetch water once kept idiosome surface wet every 6 hours
Profit, then place the 25-28 days i.e. obtained careless bricks of expelling parasite environmental protection in greenhouse.
Preferably, step 1）The device used of crushing is Miniature universal pulverizer.
Preferably, step 2）The heating-up temperature is 70 DEG C.
Preferably, step 4）The progress after idiosome is made 16 hours of fetching water first fetched water.
Wherein, described lavender belongs to Labiatae lavender platymiscium, is annual or perennial herb or shrub, is
A kind of important spices economic plants, plant is evergreen all the year round and with aromatic odor, spends generally in purple, blueness, pink, white etc.
Color, lavender has the biological action such as significantly antibacterial, anti-oxidant, and it not only achieves anti-well in field of medicaments
Bacterium is acted on, and the concern of more and more researchers is also received in terms of food, agricultural antibacterial activity.It is main in Lavender
Composition linalool can suppression microbicide activity, available for preserving fruit and vegetable utilizing, to people and mammal nontoxic residue-free, to grain and ring
Border is pollution-free, will can also turn into a kind of food preservative of novel green；Lavender is because of its fragrant, to worm worm
Serve obvious repellent action.
The expelling parasite grass refers to Pelargonium roseum, is perennial herb or shrub shape, and stem is upright, base portion lignifying, top meat
Matter, it is close by vernicose pubescence, it is savory.Expelling parasite grass is in survival temperature encloses（1-40℃）, temperature is higher, its perfume (or spice) volatilized point
Son is more, and in worm worm amount reproduction phase summer, temperature is also maximum phase, and the fragrant molecular concentration that expelling parasite vanilla is now distributed is same
It is peak period.
The lemongrass is the general designation of about 55 kinds of fragment plants of grass family Cymbopogon, also known as lemon-grass, is common perfume (or spice)
One of grass, originates in southeast subtropical zone, pyrophilous rainy weather, in area all well-growns of frostless or few frost.Due to
Well developed root system, can be drought-enduring, resistance to lean, and growth fraction is more extensive.The most important characteristic of lemongrass is exactly expelling parasite, is best suitable for being used for spraying in summer
Spill or stacte, cat and dog can also be helped to break away from tangling for flea, be a kind of natural insect prevention liquid, can with insect prevention sting, or even
Indoor oil of Cymbopogon winterianus perfume, expelling parasite, drive fly effect are good, and unlike worm perfume injury health.
Compared with prior art, the present invention has following beneficial effect：
The careless brick of expelling parasite environmental protection of the present invention uses careless slag simple and easy to get, crushed straw aggregate, granules of polystyrene as the master of careless brick
Want composition, it is environment-protecting and non-poisonous and smell is friendly, and add the lavender with good expelling parasite antibacterial effect, expelling parasite grass, lemongrass,
It is effectively improved Anti-moth-eating, the effect of expelling parasite of careless brick.In preparation method, by the way of idiosome is made, addition it is poly-
Acrylic acid ester emulsion plays a part of wetting sizing so that the careless brick structure being made is stable, high mechanical strength, is adapted to extensive raw
Production.
