Description
Technical field
The invention belongs to material engineering fields, and in particular to a kind of water-fast light, biodegradable flowerpot material and its preparation
Method.
Background technique
Natural organic filler refers to powdery, fibrous filler object made of fruit or waste using plant (crops)
Matter (i.e. filler), such as wood powder, stalk, cavings, flaxen fiber, cotton fiber, sugarcane fibre.Such fill source is in nature
Renewable resource is the further utilization of the plant not strong to agricultural waste material or other economy, therefore has inexpensive environmental protection
The advantages of.
Starch is also natural organic substance, is primarily present in seed, root tuber and the stem tuber of plant, as potato starch,
Starch from sweet potato, cornstarch, wheaten starch, pea starch etc..The method of modifying of starch, which can be divided into, is chemically and physically modified two
Major class.Chemical modification includes oxidation modification, esterification modification, cross-linking modified, graft modification etc., wherein cross-linking modified is commonly to change
Learn one of method of modifying.Adhesive strength, the water resistance and corrosion resistance energy of amylan can be improved by cross-linking reaction.Industrial starch
Glue is usually using cornstarch as raw material.
Polyvinyl alcohol (PVA) is one of ethene polymers that is less water-soluble and being biodegradable.Studies have shown that
There is the microorganisms for the PVA that can degrade in the natural environment polluted by PVA, and have therefrom extracted PVA degrading enzyme.PVA is thin
Under the action of bacterium and enzyme, 46 days degradable 75%.PVA can be used as fabric-treating agent, emulsifier, Paper coatings, adhesive,
Glue etc. uses.
Flowerpot material available on the market mainly has ceramics, plastics, timber etc..Jardiniere pattern multiplicity, but weight compared with
Big to carry inconvenience, price is also higher；Plastic flowerpot is cheap, but gas permeability is bad, it is also difficult to degrade, cause dirt to environment
Dye.Wooden flower pot is although light, but raw material sources are limited and production process is cumbersome.It develops light, inexpensive and biodegradable
Material, which makes flowerpot, has biggish economic benefit and the value of environmental protection.
Currently, the material for being used to prepare light-weight environment-friendly flowerpot can be divided into two class material of Full degradation type and Partial digestion type, entirely
Degradation-type material is mainly using biodegradable resins such as polylactic acid, polyvinyl alcohol as matrix, with natural organic substances such as starch
The flowerpot of filler preparation, this kind of material preparation can be degradable, light, but since polylactic acid, polyvinyl alcohol dosage are more, causes
The higher cost of flowerpot.And Partial digestion profile material is mainly using the virgin material of polyolefins plastics or reclaimed materials as matrix, with natural
Organic substance is filler preparation, and the flowerpot of this kind of material preparation has the advantages that common plastics flowerpot, but since polyolefins is moulded
Material does not have biological degradability, therefore this kind of flowerpot only has a Partial digestion, and degradable degree be strongly depend on it is natural organic
The additive amount of substance.
Summary of the invention
In view of the above shortcomings of the prior art, the purpose of the present invention is to provide it is a kind of it is inexpensive, light, appearance is easily beautiful
The water-fast light, biodegradable flowerpot material and preparation method thereof changed.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of water-fast light, biodegradable flowerpot material, which is characterized in that including matrix and be coated in described matrix table
The waterproof resin in face, the matrix include following raw material by weight: 60 parts of rice husk meal, 40 parts of starch, tackifier 2.5
~7.5 parts；The natural organic filler is rice husk meal, wood powder or straw powder.The natural organic fillers such as rice husk meal have and can give birth to
Object degradability and light advantage are the main components for preparing lightweight degradative flower bowl material.Starch is used to prepare amylan, forms sediment
Arogel plays cementation to natural organic filler, to collectively form material body with natural organic filler.
Wherein, the tackifier are PVA (polyvinyl alcohol)；The waterproof resin can select price lower and waterproof
The good linear phenol-aldehyde resin of property, dosage are determined according to coated area, coating thickness.
The partial size of the natural organic filler is 20~80 mesh.Granularity is excessive, and matrix can be made insecure, frangible；Granularity
It is too small, then it also will increase the weight and consumption of raw materials of matrix, also will increase the time of degradation.
A kind of preparation method of above-mentioned water-fast light, biodegradable flowerpot material, comprising the following steps:
1) cross-linking modified to starch progress, amylan is made.
2) tackifier are uniformly mixed with amylan, are formed and mixes material.
3) natural organic filler is kneaded on the double roll mill with material is mixed, obtains mixing materials；The two-roll mill
Forward and backward roll temperature be respectively 75 DEG C, 70 DEG C.
4) mixing materials are put in flash overflow mold, it is hot-forming in vulcanizing press, obtain basis material.
5) linear phenol-aldehyde resin is made into the ethanol solution that mass fraction is 9%-11%, and is coated on basis material table
Face, then dry 30min is placed in 130 DEG C of baking oven to get water-fast light, biodegradable flowerpot material is arrived.
Wherein, hot pressing temperature hot-forming described in step 4) be 115 DEG C, hot pressing pressure 8MPa.
And it cross-linking modified described in step 1) can operate such that starch, crosslinking agent, paste agent and distilled water in 70 DEG C
Under be mixed and stirred for 20min, react it sufficiently, until formed paste shape；Wherein, the mass ratio of starch, crosslinking agent, paste agent
For 1000:3:10；And the usage amount of distilled water can make starch, crosslinking agent, paste agent form paste shape just.
Wherein, the crosslinking agent selects borax, and the paste agent selects sodium hydroxide.
Amylan is made as main binder by step 1), and adds tackifier in step 2), to increase starch
The caking property of glue；Amylan is set to be uniformly mixed simultaneously hot pressing forming material ontology with natural organic filler by step 3), step 4)；
It for the water resistance for increasing material, needs to make water repellent treatment to material by step 5), so that obtaining water-fast lightweight can biology
Degradation flowerpot material.
Compared with prior art, the invention has the following beneficial effects:
1, inexpensive, degradable.The present invention is natural using the fully biodegradables such as cheap starch and rice husk meal
Organic matter is primary raw material, and the flowerpot material cost of preparation, which is far below with biodegradable resins such as polylactic acid, polyvinyl alcohol, is
The material of matrix.
2, density of material and mechanical property requirements have been taken into account.It is not difficult to find out by the raw material that the present invention uses, the flowerpot of preparation
Material weight is lighter than ceramic material；The intensity of material can be improved by adding a small amount of PVA resin and doing tackifier；Material surface is coated with
Linear phenol-aldehyde resin also improves material surface hardness more while increasing materials water-resistant.
