Abstract
A one-powder compsn. which prevents workers from making mistakes in compounding, can be transported at a low cost, does not freeze in cold seasons, and is useful for a coating material, etc., by homogeneously mixing a PVA powder with an inorg. powder and/or an org. powder in a specified ratio. The PVA powder can be dissolved in normal-temp. water without forming undissolved granules. Thus PVA can be disssolved in high concentration to form adhesive or painting.
Description
Technical field
The present invention relates to single powder type PVA composition that a kind of conduct is used to prepare the raw material of tackiness agent.In this specification sheets, " single powder type " is meant the form that makes various raw material powder uniform mixing (premixed) in advance.
Background technology
Past, under the occasion of this tackiness agent of preparation, the method that adopts is after PVA powder, inorganic powder, organic dust etc. are measured by a certain percentage, once or with every kind of component drop in the water in batches, stir, and heating as required, make the PVA powder dissolution thus in water, and other components are dispersed in the water.
, the high saponification deg PVA powder dissolution that in fact is insoluble in water must be heated herein under the occasion of water, so that the hydrogen bond between the hydroxyl of cut-out PVA.On the other hand, under the occasion of low saponification deg PVA powder in fact soluble in water, this PVA just can be dissolved in the water of normal temperature originally.But in reality, in the time of will hanging down in the saponification deg PVA powder input water, the PVA powder forms aggregate, and the PVA powder dissolution of the aggregate peripheral portion that contacts with water forms gel in water, has suppressed water soaking into to aggregate inside.This outside gel, the still undissolved PVA aggregate in inside of forming is known as so-called " dough ".In case become this dough state, then the PVA powder all dissolves and need take long to.Therefore, must make the PVA powder dissolution by raising water temperature, high-speed stirring.
Do not make low saponification deg PVA form the dissolving method of dough, be disclosed in special public clear 32-4342 communique and the special public clear 32-9887 communique.These methods are to make the saltout aqueous solution of the big inorganic salts such as sodium sulfate of power of PVA is impregnated in the PVA powder cryodrying then or makes it and boric acid blended method.But, these methods to PVA concentration be 4% or the washing of lower concentration stick with paste effectively, and invalid to the higher concentration about 10%.
Past, this with multiple materials such as PVA powder, inorganic powder, organic dust in accordance with regulations the operation of proportioning metering not only need the time, and under the unskilled occasion of operator, probably can not measure cooperation in accordance with regulations.And, to use under the occasion of liquid emulsion, handling for useless jar after the use also becomes problem.
And, under the occasion of high saponification deg PVA powder, need heating unit improper during the PVA powder dissolution to the occasion that has as raw material.On the other hand, to hang down saponification deg PVA powder dissolution at normal temperatures under the occasion of water, easily produce the dough state, employing can be avoided under the occasion of disclosed method in the public clear 32-4342 communique of above-mentioned spy of these shortcomings and the special public clear 32-9887 communique, must carry out complicated pretreatment, in addition, also exist the low shortcoming of dissolved PVA concentration.
In addition, the PVA composition is become under the liquid occasion, exist the problem that weight causes transportation cost to rise, freeze in algid stage greatly.
Summary of the invention
The object of the present invention is to provide a kind of tackiness agent mono-powder compositions, said composition can not cause that the cooperation mistake of PVA composition appears in operator, and transportation cost is cheap economical, and does not have the possibility that algid stage freezes.
Another object of the present invention is to provide a kind of tackiness agent mono-powder compositions, and said composition does not need heating unit when the PVA powder dissolution, can dissolve in the water of normal temperature and does not form the dough shape.
Another object of the present invention is to provide a kind of tackiness agent mono-powder compositions, and said composition can make the desired high density PVA of tackiness agent dissolve.
The 1st invention of the present invention be a kind of with inorganic powder and/or organic dust by a certain percentage uniform mixing go into the tackiness agent mono-powder compositions that forms in the PVA powder.
The 2nd invention of the present invention be a kind of with inorganic powder and/or organic dust and powder additive by a certain percentage uniform mixing go into the tackiness agent mono-powder compositions that forms in the PVA powder.
By making PVA powder and other powder uniform mixing, around the PVA powder, dispose powder such as inorganic powder or organic dust thus, when dropping into this mono-powder compositions in the water, the PVA particle in the water is difficult to direct contact each other.
The 3rd invention of the present invention is the invention described in the above-mentioned the 1st or the 2nd, and the saponification deg that is a kind of PVA powder is the tackiness agent mono-powder compositions of 75 moles of %～99 mole %.
Saponification deg surpasses under the occasion of 95 moles of %, must make the PVA powder dissolution in hot water.If saponification deg is 75 moles of %～95 mole %, this PVA powder is dissolvable in water in the water of normal temperature.Under this occasion, owing to have powder beyond the PVA powder, can make the PVA powder not form the dough state and be dissolved in the water of normal temperature.
The 4th invention of the present invention is above-mentioned 1～3 invention described in each, is the tackiness agent mono-powder compositions that a kind of median size of PVA powder is lower than 4mm.
In fact the median size of PVA powder is very big influence factor to saponification deg and the solubleness in water, if the median size of PVA powder is lower than 4mm, then can be dissolved in the warmed-up water.
