Abstract
The invention relates to a starch adhesive for wall paper and a preparation method thereof. The starch adhesive for wall paper consists of the following raw materials in percentage by weight: 100 percent of starch, 2.2-2.4 percent of potassium permanganate, 1.8-2.0 percent of initiator, 10-15 percent of sodium hydroxide, 1.0-2.0 percent of borax, 5-10 percent of flowable agent, 570-600 percent of water and 5-8 percent of urea-formaldehyde glue. The starch adhesive for wall paper has the characteristics of strong bonding force, high flowability, nontoxicity, odorlessness, high drying speed and the like.
Description
Technical field
The present invention relates to a kind of wallpaper with starch adhesive and preparation method thereof, belong to the composite modified starch technical field.
Background technology
Starch adhesive more and more is used widely as universal natural adhesive, and this is mainly based on two reasons, and the one, starch resource is abundant, low price, and nontoxic free from extraneous odour, pollution-free; The 2nd, along with the minimizing day by day of petroleum resources, the Chemicals that award oil and be raw material have constituted threat, thereby make many enterprises seek surrogate one after another; And the simple Starch Adhesive that uses exists the viscosity instability as wallpaper glue in the wallpaper industry; Rate of drying is slow, problems such as bonding strength difference, and make the change of starch structure, physical properties and chemical property through physico-chemical process or biochemical method; Multiple denaturation cornstarch tackiness agent with specified property and purposes appears; This corn starch adhesive has bonding strength height, in light weight, characteristics such as non-corrosiveness, thus receive extensive concern.
Because it is unstable that corn starch adhesive ubiquity in practical application viscosity, rate of drying is slow, problems such as bonding strength difference, and the modified starch adhesive that the present invention and an amount of urea-formaldehyde glue blend make has good adhesiveproperties.
Summary of the invention
The purpose that the present invention is is exactly that the viscosity that exists to existing wallpaper starch adhesive is unstable, and rate of drying is slow, and problems such as bonding strength difference provide that a kind of to have a bonding force strong, good fluidity, and nonpoisonous and tasteless, the fast wallpaper of rate of drying is used starch adhesive.
The present invention realizes through following technical scheme, it is characterized in that this wallpaper is made up of following materials of weight proportions with starch adhesive: starch 100; Potassium permanganate 2.2～2.4; Amount of initiator 1.8～2.0; Sodium hydroxide 10～15; Borax 1.0～2.0; Flowing agent 5～10; Water 570～600; Urea-formaldehyde glue 5%～8% is formed
Its starch is W-Gum or potato starch; Its urea-formaldehyde glue following raw materials according is formed: urea 1.0～2.0; Formaldehyde 1.8～2.2; Hexamethylenetetramine 0.5～0.8.
Its preparation method is:
(1) preparation of amylan
By a certain percentage starch is added water and in reactor drum, stir the starch emulsion of preparing written treaty 40%; Add potassium permanganate solution, regulate pH value, starch emulsion is filtered, washs to neutral; The filter cake that obtains adds water and stirs a small amount of initiator of adding; Use the dissolution of sodium hydroxide gelatinization, behind the 20min, add borax again and mix subsequent use.
(2) urea-formaldehyde glue preparation
By a certain percentage formaldehyde is added and drip hexamethylenetetramine adjustment pH value in the reactor drum while stirring, add urea and be warming up to about 90 ℃, drip hexamethylenetetramine adjustment pH value while stirring, adding formaldehyde again, to be cooled to 45 ℃ of left and right sides subsequent use.
(3) preparation of starch adhesive
In the process that the limit edged stirs in the reactor drum of amylan about 45 ℃ of not discharging, add 5% urea-formaldehyde glue and stir and to reduce to discharging after the room temperature, the container of packing into after fully stirring about 45min.
Embodiment
(1) preparation of amylan
By a certain percentage 100 parts of starch are added water and in reactor drum, stir the starch emulsion of preparing written treaty 40%; Add 2.2 parts of potassium permanganate solutions, regulate pH value, starch emulsion is filtered, washs to neutral; The filter cake that obtains adds water and stirs 2 parts of initiators of adding; With 10 parts of dissolution of sodium hydroxide gelatinizations, behind the 20min, add 2 borax again and mix subsequent use.
(2) urea-formaldehyde glue preparation
By a certain percentage 1.8 parts of formaldehyde are added and drip 0.3 hexamethylenetetramine adjustment pH value in the reactor drum while stirring; Adding 1 part of urea is warming up to about 90 ℃; Drip 0.2 hexamethylenetetramine adjustment pH value while stirring, adding 0.2 part of formaldehyde again, to be cooled to 45 ℃ of left and right sides subsequent use.
(3) preparation of starch adhesive
In the process that the limit edged stirs in the reactor drum of amylan about 45 ℃ of not discharging, add 5% urea-formaldehyde glue and stir and to reduce to discharging after the room temperature, the container of packing into after fully stirring about 45min.
Claims (4)
