Abstract
The present invention provides a water-soluble cellulose ether composition that is improved in fluidity and other flow properties to attain much better coating property, when it is applied as a sizing agent for wall paper and shows excellent work efficiency, economy and the like by adding a specific surfactant to the sizing composition.
Description
The present invention relates to water soluble cellulose ether composition and sizing material, by in water-soluble cellulose ether, adding flow promoting agent, the flowability when having promoted to form the aqueous solution, therefore, be highly susceptible to coating when being coated with sizing material etc. as wallpaper, operating efficiency, economy etc. are good.
As the wallpaper sizing material, always use the water soluble starch solution that is referred to as " paste of cooking a meal ".These sizing materials must use being scaled with solids fraction under 20% the degree, are dense starch paste solution, therefore, are diluted with water to several times～10 times degree usually and use.In addition, because commercially available,, add formalin or sanitas for can prolonged preservation as solution.
In recent years, consider environmental problem etc., the result is popularizing the method that the water-soluble cellulose ether powder or the granular product of instant type dissolve use in use.Use the advantage of instant type water-soluble cellulose ether, can enumerate: because solid is also preserved same as before when using, so needn't add sanitas etc.; Because it is full-bodied comparing with starch etc., so usage quantity can be dealt with problems to the degree of percentum etc. less.
But in the occasion of the wallpaper that only contains water soluble cellulose ether with sizing material, the viscosity of solution is big, and therefore following shortcoming is arranged: or the coating thickness of sizing material becomes unnecessary thick, or may be coated with inequality when being coated with without a break with hairbrush or roller.
The present invention is exactly for to improve above-mentioned shortcoming, the objective of the invention is to, by in water-soluble cellulose ether, adding flow promoting agent, promote the flowability when it forms aqueous solution, thereby good water soluble cellulose ether composition and sizing materials such as a kind of that be highly susceptible to being coated with when being coated with sizing material etc. as wallpaper, operating efficiency, economy are provided.
The inventor has carried out research with keen determination for achieving the above object, and found that, by contain flow promoting agent in water-soluble cellulose ether, just can promote the flowability of the water soluble cellulose ether composition aqueous solution, thereby finish the present invention.
Thereby, the invention provides
(1) water soluble cellulose ether composition is characterized in that, contains water-soluble cellulose ether and flow promoting agent.
(2) water soluble cellulose ether composition described in (1) is characterized in that, flow promoting agent is that polyethers based compound or derivatives thereof or organophosphorus are tensio-active agent.
(3) sizing material of forming by above-mentioned (1) or (2) described water soluble cellulose ether composition.
Below the present invention will be described in more detail, water-soluble cellulose ether of the present invention is not particularly limited, but generally use HYDROXY PROPYL METHYLCELLULOSE, hydroxy ethylmethylcellulose, viscosity is in 1% viscosity in aqueous solution, down use 10～22000mPas at 25 ℃, be preferably 100～10000mPas's.When viscosity is counted not enough 10mPas with 1% viscosity in aqueous solution, necessary viscosity deficiency, perhaps addition is very many, when viscosity is too high, operability is worsened.
The shape of water-soluble cellulose ether, and though powder, granular product all can, but consider the situation of transportation, be good with the few granular product of dust from flying.
In addition, composition of the present invention is dissolved in the water when using as sizing material, and water-soluble cellulose ether is 0.2～5% (weight %, down together) to the addition of water, is preferably 0.5～3%.During the addition less than 0.2% of water-soluble cellulose ether, worsen because of the viscosity deficiency makes bounding force, surpass at 5% o'clock, viscosity is too high to make the operation deterioration, and cost becomes very high in addition.
As flow promoting agent of the present invention, can enumerate polyethers based compound or derivatives thereof or organophosphorus is tensio-active agent.Specifically, as polyethers based compound or derivatives thereof, can enumerate the polymkeric substance of polymers of ethylene oxide, propylene oxide, be ジ ョ Le シ Application LX, ジ ョ Le シ Application PB, ジ ョ Le シ Application LB-D of tensio-active agents (particularly nonionogenic tenside) such as the multipolymer of oxyethane-propylene oxide of general name or their derivative, polypropylene glycol, polyoxyethylene glycol, glycerine, ダ イ ヤ Off ア イ Application society system etc. as Pu Luluonike.In addition, be tensio-active agent as organophosphorus, can enumerate tributyl phosphate, octyl group sodium phosphate.
The addition of flow promoting agent is not particularly limited, but for water-soluble cellulose ether 0.1～20%, particularly be good in 0.5～10% scope.Addition is less than at 0.1% o'clock, can not get the effect that flowability substantially improves, on the other hand, even surpass 20%, then not only mobile facilitation effect to the end, and cost uprises.
In addition, as the addition means of flow promoting agent in water-soluble cellulose ether, can be in the aqueous solution of water-soluble cellulose ether, directly to add flow promoting agent to stir again, mix, but consider the situation of transportation, in advance flow promoting agent is added in the water-soluble cellulose ether to good.That is, can enumerate flow promoting agent is contained the method that is dipped in the water-soluble cellulose ether, flow promoting agent is contained be immersed in the micropowder silica, again it is done the method for mixing in water-soluble cellulose ether.
Flow promoting agent is involved in bubble when making solution stirring, but it also has defoaming effect simultaneously, and therefore second effect of removing these bubbles, becoming uniform solution is also arranged.
Embodiment
Embodiment and comparative example below are shown, the present invention is specifically described, but the present invention is not subjected to the qualification of following embodiment.
[embodiment, comparative example]
Water-soluble cellulose ether and other reagent are pre-mixed,, make the aqueous solution by 2 weight % dissolving.Stirred 5 minutes, and till the viscosity that the initial stage occurs, placed then 1 hour, estimate again.
The measuring method of flow of solution is with the rod of each 20g of solution along the glass of 45 degree inclinations, hangs with certain speed, measures the length of the solution of being wandered by the front end of rod.It is good that the molten shape that solution length is long improves effect, and short do not have an effect.
