Abstract
The invention provides a polylactic acid colloid formula and a preparation method thereof, comprising the steps as follows: polylactic acid master batches and solvents are mixed in a container till that the polylactic acid master batches are completely dissolved and present transparent dispersed liquid; subsequently, the water is removed by a molecular sieve, thus forming the polylactic acid colloid formula with 1-85% of the effective solid ingredients by weight proportion.
Description
Technical field
The invention relates to a kind of polylactic acid colloid formulation and preparation method thereof, and particularly drench film colloid formulation and preparation method thereof relevant for a kind of PLA paper.
Background technology
Along with environmental consciousness promotes gradually, for the requirement of the food-safety problem of being derived of disposable packaging for foodstuff paper wood and garbage disposal problem etc. also increasingly stringent, present trend is to use biological decomposable paper wood to replace materials such as plastic cement, Poly dragon, to reduce the burden of earth environment.
Because paper wood itself does not possess waterproof, anti-wet goods function; therefore can have an insulation layer as the paper wood of packaging for foodstuff usually with the food contact-making surface; for example use PE leaching membrane paper, paraffin paper, wax cup etc.; promptly be on body paper, to add waterproof grease proofing material layer (PE, wax etc.), to reach the purpose of waterproof and oilproof.
General common cold drink cup is that wax is coated with on the dixie cup, utilizes wax to meet cold phenomenon and wax good waterproof effect that can hardening, makes the cold drink cup can the deliquescing because ice cube melts, but therefore splendid attire beverage.Yet wax can be met heat and be melted, and causes the problem on the food security on the contrary, so wax cup, paraffin paper are not suitable for the heat food.
As drenching film jelly material, again attached to paper wood surface, can form the film of a heat-resisting and waterproof and oilproof after coinciding with paper with plastics (for example PE), therefore present many wrapping papers and dixie cup all utilize the PE leaching membrane paper to make.Yet PE is petroleum chemicals, though cheap, stand on the position of paying attention to environmental protection and food hygiene, the PE leaching membrane paper is applied on the very big disposable food packing material of consumption, still have environmental protection and safe misgivings.In addition, PE drenches film and only is attached to the paper wood surface, is applied on the non-once use packing timber, for example on the purposes such as medicine bag, fruit anti-water cap bag, because paper wood and PE drench film degree of adhering to the shortcoming that is come off by breakage is arranged inadequately and easily again.
Summary of the invention
Therefore the present invention is providing a kind of PLA paper to drench film colloid formulation and preparation method thereof, but utilizes paper wood and PLA to be the characteristics of biology decomposing material, replaces traditional leaching membrane paper, can be made into complete biolytic leaching membrane paper.
Another aspect of the present invention is to provide a kind of PLA paper to drench the film colloid formulation, can embed the paper wood fiber, improves tradition and drenches film formulation and only be attached to the paper wood surface, removed the shortcoming that comes off easily.
According to the present invention, a kind of polylactic acid colloid formulation and preparation method thereof is proposed, polylactic acid colloid formulation is to contain effectively to consolidate the liquid jelly of PLA that composition is 1～85% weight ratio, can embed the paper wood fiber, in order to make complete biolytic leaching membrane paper.
The preparation method of polylactic acid colloid comprises a PLA master batch and a solvent, in container, stir, until the PLA master batch dissolve fully present transparent dispersing liquid after, the alternative auxiliary agent that adds forms the polylactic acid colloid formulation that is applicable to different paper woods.
Drench the film colloid formulation according to above-mentioned PLA paper of the present invention as can be known, be a kind of transparent dispersing liquid, can embed the paper wood fiber and can't be removed and come off.The preparation method that PLA paper drenches the film jelly is one simply and the processing procedure that carries out easily, and the polylactic acid colloid of making can have different ranges of application according to the difference of the auxiliary agent of effective solid content ratio and interpolation.
Description of drawings
For allowing above-mentioned and other purposes, feature, advantage of the present invention and buy Shi Lineng and become apparent appended graphic being described in detail as follows:
Fig. 1 is the preparation flow figure of a kind of polylactic acid colloid of the embodiment of the invention.
[main element symbol description]
110: step 120: step

The specific embodiment
Please refer to Fig. 1, be preparation flow figure according to a kind of polylactic acid colloid of the embodiment of the invention.The preparation method of polylactic acid colloid comprises the following step:
With reference to shown in the step 110, a container at first is provided, this container can comprise closed container or open container, and closed container is a reactor for example, has in the reactor to stir or mixing arrangement; Open container is an agitator tank (bath) for example, agitator tank (bath) can be any material applicatory, for example glass, metal or plastic cement.
Then shown in step 120, the water of the PLA master batch of adding 1～85% weight ratio, the solvent of at least 15% weight ratio and effective dose forms a mixture in container.According to embodiments of the invention, it is 74.1～204.3 alcohol, ketone, ether or ester class that solvent can wrap range of molecular weight distributions.
Shown in step 130, stir the mixture that this PLA master batch and solvent form, dissolve fully until the PLA master batch and present a transparent dispersing liquid, being formed with effectively admittedly, composition is the liquid jelly of PLA of 1～85% weight ratio.According to embodiments of the invention, can select when step 130 is carried out, to apply a heat energy simultaneously, to quicken the dissolving of PLA master batch in this mixture.
According to one embodiment of the invention, more be contained in the liquid jelly of PLA and add a modification agent, modification agent can comprise polyalcohol, polynary ester class, is to be selected from the group that is made up of ethyl acetate, beeswax, sorbierite, natural rosin ester and above-mentioned any combination.
According to another embodiment of the present invention, more be contained in adding one interfacial agent in the liquid jelly of PLA, wherein HLB value (hydrophile-lipophilebalance) scope of interfacial agent is between 3～14.
At last, shown in step 140, filter the liquid jelly of PLA, and dewater with molecular sieve.According to embodiments of the invention, molecular sieve is 40 order numbers (mesh).
Though the present invention discloses as above with embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the accompanying Claim person of defining.
