Description
Technical field
The present invention relates to roof greening technologies, and in particular to a kind of for the thermoplastic blanket of roof greening and its preparation side
Method.
Background technology
Roof greening is different from the general greening on ground, there is certain particularity.And water-storage-drainage layer, filter layer and matrix
Important component of the layer as structure of Roof Greening hierarchical system, needs to consider following aspect simultaneously：
(1) water-storage-drainage layer generally comprises drainage plate, pottery gravel (load uses when allowing) and drainpipe (the roof drainage gradient
Used when larger) etc. different drainage forms, for improving the aeration status of matrix, discharge excessive moisture rapidly, it is effectively slow
Instantaneous pressure is solved, and a small amount of moisture can be stored.
(2) effect of filter layer is that matrix is prevented to enter drainage blanket.Filter layer will ensure the function of having draining, except this it
Outside, drainpipe sediment siltation is also prevented.It is general using can permeable and filtrable polyester fiber non-woven fabric etc.
Material.
(3) hypothallus refers to meet plant growing condition, has certain permeance property, water-holding capacity and spatial stability
Light material layer.Need to have three primary conditions for the planting matrix of roof greening：There is certain retain water and nutrients ability, thoroughly
Gas is good；There is certain chemical buffer ability, keep ratio of good water, gas, nutrient etc.；Light-weight, ideal matrix is held
Weight should be in 0.1~0.8T/m3, generally use and be uniformly mixed by turf, Nutrition Soil, garden mould etc. according to different proportion.
At present, domestic is difficult to have the functional need that a kind of roof greening material can meet roof greening filter layer and hypothallus
It asks, therefore has during practical roof greening construction according further to different roof construction layers using different construction materials, it is different
Construction technology technology, construction is complex cumbersome, time-consuming.And some can meet filtering in existing roof greening material
The functional requirement of layer, some can meet the functional requirements of hypothallus.But a kind of rare roof greening host material can meet
The functional requirements of filter layer, and the functional requirements of hypothallus can be met.
Invention content
It can meet simultaneously it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of
It is filtering layer and matrix layer function, low-cost for thermoplastic blanket of roof greening and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：A kind of thermoplastic blanket for roof greening, should
Thermoplastic blanket includes the substance of following weight percent：
Polypropylene short fiber 25~45%；
Cotton 30~50%；
Aramid fiber 25~45%.
Using the component of the ratio so that final material lightweight, and with good water holding capacity, in addition, cotton and fibre
The raw material such as material processing synthesis is tieed up in itself containing a large amount of organic matter, we mix sustained release also in thermoplastic blanket process
Fertilizer can play facilitation to the growth in plant later stage.Moreover, these three substances are environmentally protective, there is high resiliency, high durable
Property, sound insulation, it is heat-insulated the characteristics of, be very suitable for used in roof greening.
The dry weight of the thermoplastic blanket is 0.1~0.3T/m3, after tested, according to the THICKNESS CALCULATION of thermoplastic blanket 1cm, put down
Aqueous 5.39 kilograms of every square metre of saturable can play the function of water draining and accumulating, and promotion is played to sponge urban construction and development and is made
With.
The thickness of the thermoplastic blanket is 0.5~3cm.
A kind of preparation method for the thermoplastic blanket for being used for roof greening as described above, including following steps：
(1) by discarded linen-cotton material clothing is classified, shredding obtains raw material cotton, polypropylene chopped fiber peacekeeping aramid fiber；
(2) cotton of gained, polypropylene chopped fiber peacekeeping aramid fiber are proportionally mixed and is stirred, combs, at high temperature
Baking obtains molten thermoplastic fibre；
(3) molten thermoplastic fibre is compacted, then cooled down up to the thermoplastic blanket.
The raw material sources of thermoplastic blanket of the present invention have been accomplished waste utilization, have been not only acted as energy saving in waste and old clothing
The effect of environmental protection, moreover it is possible to the production cost of enterprise is greatly reduced, moreover, causing final thermoplastic blanket product not using the raw material
Containing harmful substances such as arsenic, ammonia, formaldehyde, have no irritating odor.
Stoving temperature described in step (2) is 250-280 DEG C, and baking time is 1~5min.At this temperature, molten
The mobility of thermoplastic fibre is stronger, is more advantageous to three kinds of raw materials and is uniformly mixed.
Compared with prior art, beneficial effects of the present invention are embodied in following several respects：
(1) raw material sources of thermoplastic blanket recycle by processing in discarded chemical fibre, clothing etc., play energy-saving ring
The effect of guarantor；
(2) contain matrix in thermoplastic blanket, the raw material such as cotton and fibrous material processing synthesis is in itself containing a large amount of organic
Matter, we also mix slow-release fertilizer in thermoplastic blanket process, can play facilitation to the growth in plant later stage；
(3) thermoplastic blanket can play a role in filtering as roof greening materials'use, medium to plant medium layer, miscellaneous
Object plays the role of filtering；
(4) thermoplastic blanket of the invention has good retain water and nutrients ability, and good permeability has certain chemical buffer energy
Power keeps ratio of good water, gas, nutrient etc.；According to the THICKNESS CALCULATION of thermoplastic blanket 1cm, average every square metre of saturable
Aqueous 5.39 kilograms, the function of water draining and accumulating can be played, facilitation is played to sponge urban construction and development；
(5) thermoplastic blanket light weight of the invention, dry weight are 0.1~0.3T/m3, 0.5~0.65T/m of weight in wet base3, it is lighter than city
The hypothallus sold.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment is carried out lower based on the technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
