Description
Technical field
The present invention relates to a kind of wood plastic composite more particularly to a kind of manufactures preparing wood moulding heating floor using stalk
Method.
Background technology
China is a traditional large agricultural country, the annual all kinds of agricultural crop straws for generating about 800,000,000 tons, main application way
Diameter has straw-returning, stalk energy, processing feed, artificial board of straw etc., but also has more than half stalk resource to fail
It is utilized to rationally effective, is often incinerated, forms larger pollution to air.
With the fast development of ceramic industry, ceramic industry waste material is increasing, according to measuring and calculating, China only wall, floor tile production
The annual green compact waste product for just generating about 500,000 tons, these porcelain stone wastes are usually in a manner of the simple process accumulated and filled
It is main, cause soil, the huge waste of mineral resources and environmental pollution.
Therefore, it if being reprocessed into product being used after stalk and ceramic scrap concrete, can not only reduce
The discharge of waste, reduces environmental pollution, and economic recyclability may be implemented, and has higher environmental benefit and economy
Benefit.
Recent domestic scientific research begins to use stalk and thermoplastic to prepare composite material, as replacing for Wood products
Dai Pin is widely used in garden landscape, outdoor deck, outdoor furniture and transportation and packing industry etc..But as household ring
The also very rare of wood plastic composite is directly used in border in important heating floor, this is primarily due to the heat of heating floor
Source is generally embedded in underfloor hot-water line, heating cable etc..Due to the particularity of heating floor heating, floor is necessary
Has the good requirement of good excellent heat conductivity, thermal stability, deformation resistance, good mechanical performance, the resistance to rotten and feature of environmental protection.Mesh
The preceding Wood-plastic floor sold on the market is typically to add related auxiliaries using plant fiber and thermoplastic, and melt blending squeezes
Go out molding, that there are wood fibres is poor with thermoplastic interface compatibility, heat conduction efficiency is low, poor dimensional stability, easily sticks up
The problems such as bent, can only use as common household floor, cannot meet the demand of heating floor increasingly extended.
Invention content
The object of the present invention is to provide a kind of straw base wood moulding heating floor and its processing method, which is with crops
Stalk (cornstalk), the green scrap in Ceramic manufacturing enterprise, based on thermoplastic (PVC and polyether block amide blend)
Raw material is wanted, wood moulding heating floor is manufactured by processes such as crushing, pretreatment, high mixed, extrusion, health, overlay films；The floor has
Higher heat conduction efficiency, mechanical property, lower coefficient of thermal expansion, resistance to decadent nature and it is not easy buckling deformation, can be widely used in
Heating floor field has good market prospects.
The present invention solves technical problem and uses following scheme：
A kind of straw base wood moulding heating floor, feature are, are made of in mass ratio following component, PVC and polyether block
Amide blend 25-30%, nano bamboo charcoal powder 5-7%, porcelain stone powder 20-25%, lubricant 2-4%, coupling agent 5-7%；It is remaining
It is divided into cornstalk.
Preferably, each component mass ratio is cornstalk 35%, PVC and polyether block amide blend 30%, nanoscale
Bamboo charcoal powder 7%, porcelain stone powder 20%, lubricant 2%, coupling agent 6%.
Preferably, the PVC and polyether block amide blend in mass ratio 6:4 ratio mixes.
Preferably, the lubricant is the mixture of stearic acid and ethylene bis stearic acid amide, in mass ratio 3：7 ratio
Example mixes.
Preferably, the coupling agent is long-chain chlorinated paraffin.
A kind of processing method of straw base wood moulding heating floor is claimed simultaneously in the present invention, and feature is, including such as
Lower step：
1) it is put into milling in flour mill after being respectively crushed cornstalk to handle, 200 mesh particles are obtained after screening process；
2) cornstalk particle is put into bamboo vinegar (PH<2.2) it in, is fully impregnated 24 hours under the conditions of temperature is 50 DEG C；
3) it after taking out cornstalk particle, after being rinsed well using clear water, is taken out after spontaneously drying；In 110 DEG C of baking oven
Under temperature condition, be dried within 24 hours, the average moisture content of wood-fibred is made to be reduced to less than 2%；
4) it is put into flour mill after being crushed porcelain stone or porcelain stone waste material and carries out milling processing, 250- is obtained after screening process
300 mesh porcelain stone powder；
5) cornstalk particle and porcelain stone powder are put into high speed first mix dispersion machine heating and mix to 90 DEG C, then by PVC and
Polyether block amide blend, nano bamboo charcoal powder put into after high speed mixing dispersion machine is warming up to 125-130 DEG C and mix 20 together
Minute, be subsequently cooled to 45 DEG C again will lubricant and coupling agent input mixed at high speed dispersion machine in mix 30 minutes for use；
6) pellet mixed is put into conical-double -helical rod extruder hopper, 180 DEG C -190 DEG C of temperature, revolution 25r/
Wood-plastic clad plate is made in min-30r/min, extrusion；
7) after taking out wood-plastic clad plate, it is placed on health under room temperature 48 hours；
8) wood-plastic clad plate is finally obtained into wood moulding wood moulding heating floor finished product by laminating machine overlay film.
Compared with the prior art, the present invention has the beneficial effect that：
The present invention utilizes the green scrap in agricultural crop straw (cornstalk) and Ceramic manufacturing enterprise, substitutes a large amount of wooden
Material, and by formulation optimization, the heating floor being prepared has higher thermal coefficient, lower coefficient of thermal expansion, and
It is not easy buckling deformation, heating floor field can be widely used in, there are good market prospects.
The natural macromolecular material that cornstalk fibers are made of cellulose, hemicellulose, lignin and extract etc.,
Interfacial characteristics are sufficiently complex.Meanwhile form the cellulose of cornstalk fibers material, hemicellulose, lignin etc. main components
In containing the functional groups such as a large amount of polar hydroxyl groups, phenolic hydroxyl group, there is very strong chemical polarity.Therefore, to the table of cornstalk fibers
Face carries out chemical modification, changes the state on cornstalk fiber surface, to achieve the purpose that improve surface compatability.The present invention uses
Bamboo vinegar is a kind of to the non-harmful bamboo charcoal processing byproduct of environment, this is synthesis compound (hydrochloric acid, acetic acid, oxalic acid, phosphoric acid
Deng) not available for.Bamboo vinegar carrys out modified corn stalk fiber, this has more advantage compared with single acid compounds,
Bamboo vinegar is a kind of more complicated mixture of component, and classes of compounds is mainly organic acid, alcohols, ketone, phenols, ester
Class, aldehydes etc., some of ingredients itself have preferable antibacterial action, are a kind of natural antiseptics.Bamboo vinegar is modified beautiful
Other than the esterification of normal acid compounds occurs the reactions such as alcoholization and graft copolymerization can also occur for rice stalk fiber,
Cornstalk fibers are made to produce hydrophobic nonpolar chemical functional group, it is more secured with frosting interfacial bonding property.Therefore, pass through
Wood plastic composite prepared by the modified cornstalk fibers of bamboo vinegar has better mechanical property and antiseptic property.
Straw base wood moulding heating floor plastic substrate of the present invention can be improved using PVC and polyether block amide blend
Thermal stability, ageing resistance, shock resistance and the interface compatibility with cornstalk of PVC matrix.
Straw base wood moulding heating floor plastic substrate of the present invention be added nano bamboo charcoal powder can fill cornstalk fibers with
Interfacial gap between plastic substrate improves mechanical property, thermal conductivity and the thermal stability of straw base wood moulding heating floor.It is added
Porcelain stone powder can further increase the thermal conductivity and thermal stability of straw base wood moulding heating floor.
