Abstract
The invention discloses a process for producing moisture-proof starch glue and aims at providing a carton pulping process which can enhance the strength of cartons and decrease deformation caused by the fact that the cartons are influenced by environmental factors. The process for producing the moisture-proof starch glue is characterized by sequentially comprising the following steps that (1) 500-600 parts by weight of water and 40-50 parts by weight of cassava starch are added into a tank body and are stirred for 4-6 minutes to be suspended, 8.0-9.0 parts by weight of caustic soda flakes are added, and stirring is performed for 30 minutes to obtain processed glue; (2) 800-1000 parts by weight of water is added into the tank body, then 6-8 parts by weight of borax is added, stirring is performed for 4-6 minutes, then 400-410 parts by weight of cassava starch is added, stirring is performed till a mixture is suspended, and raw glue is obtained; (3) the processed glue obtained in the step (1) and the raw glue obtained in the step (2) are mixed, 18 parts by weight of moisture-proof agent is added, and stirring is performed for 15 minutes to obtain the moisture-proof starch glue.
Description
Technical field
The present invention relates to a kind of production technique of glue, specifically, is a kind of production technique of moistureproof starch glue.
Background technology
Existing production enterprise of China, use amylan as binding agent, the defects such as the cardboard of making also exists cohesive strength difference, the accumulation of salt in the surface soil moisture absorption, yielding, the defects such as adhesive-preparing technology also exists complex procedures, formula suitable marquis's property is poor, and unstable, the easy layering and precipitating of product viscosity, storage period are short, what existing adhesive-preparing technology adopted is all common starch, made paste needs when producing high grammes per square metre paper the additive increasing other, the consumption of alkali is too high, cardboard will turn to be yellow, differences in viscosity, false sticky, easily crisp, the moisture absorption, easily broken, mobility is bad, initial bonding strength is not strong, viscosity is unstable, and gelatinization point is low, particularly make Nine Dragons and block 170G in vain, during the high grammes per square metre body paper of more than Nine Dragons 210G, cardboard both sides there will be the situation having 5-10 centimetre Poor cohesion, and the main raw material(s) of additive has parathyrine formaldehyde, ammonia, the compositions such as chlorine, not environmentally, using in workshop has dazzling pungent contact skin to itch.
Carton pulping process conventional on market feeds intake, interpolation W-Gum, sheet alkali, borax, water stir by a certain percentage and make slurry, but the carton of damp state limit pressure prepared by this slurry, product is easily received such environmental effects and is occurred moisture regain, reduces in intensity in long-distance transport process, there is packing of product potential safety hazard.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide one can strengthen carton intensity, moisture effect is good, reduces the distortion that it causes by such environmental effects.
For solving technique scheme, technical scheme provided by the invention is such:
A production technique for moistureproof starch glue, comprises the steps: successively
1) ripe glue makes
By adding 500-600 weight parts water in tank body, 40-50 weight part tapioca (flour), stirs 4-6 minute to suspension, adds 8.0-9.0 weight part sheet alkali, within 30 minutes, namely obtain ripe glue in stirring;
2) rubber makes
In tank body, add 800-1000 weight parts water, then add 6-8 weight part borax, stir 4-6 minute, then add 400-410 weight parts water tapioca (flour), be stirred to suspension and namely obtain rubber;
3) finished product glue makes
By step 1) the ripe glue that makes, step 2) the rubber mixing that makes, add 16-20 weight part non-blushing thinner, stir 15 minutes, to obtain final product.
Further, the production technique of above-mentioned moistureproof starch glue, step 1) described in sheet buck dilution after add.
Further, the production technique of above-mentioned moistureproof starch glue, step 2) described in borax hot water dissolve and to be evenly sprinkled into afterwards.
Further, the production technique of above-mentioned moistureproof starch glue, step 3) described in non-blushing thinner be epoxy resin.
Compared with prior art, W-Gum is changed to tapioca (flour) by conventional slurrying formula by technical scheme provided by the invention, and add non-blushing thinner in pulping agents, take the pulping way of two-step process to distinguish ripe glue and rubber, and stir after completing as procedure for producing glue.Stablize carton intensity, reduce the distortion that it causes by such environmental effects, carton intensity improves about 5%-8% on original formulation basis, uses flow cup and stopwatch to test the viscosity of its finished product glue, 23 ± 2 seconds; Gelatinization point, 58-60 DEG C,
