Abstract
The invention discloses a starch bonding agent for carton production and a preparation method of the starch bonding agent. The starch bonding agent relates to a macromolecule resin bonding agent, and in particular relates to a resin bonding agent for carton bonding. The resin bonding agent for carton bonding is prepared from modified starch, caustic soda, water, borax and an additive, wherein the additive mainly comprises urea-formaldehyde resin (-(CH2-N-CO-N-CH2)-1), polyving akohol, medical membrane resin and a glue liquid stabilizer (a developed formula of high-elastic-modulus waterproof alkali gelatinization modified starch composite resin bonding agent is shown in abstract attached list 1). Through the scientific temperature control and the accurate control of the quantity of raw materials and the additive, the prepared bonding agent has obvious high-adhesion and water proof performances and the like; and compared with the common carton product, the carton produced by the bonding agent provided by the invention as the raw material has the characteristics of long service life, light quality, high stability and the like.
Description
(1) technical field
The invention belongs to the high molecular resin binder field, is to utilize W-Gum to be suitable for the polymer compound resin tackiness agent that corrugated board production is used through what sex change was processed.
(2) background technology
Tackiness agent (having another name called tackiness agent) is the important raw and processed materials of corrugated cardboard mount, and tensile strength, Young's modulus and water tolerance are to weigh the two big important indicators of glueing joint the cardboard quality, are concerning the work-ing life of corrugated cardboard.Cause corrugated cardboard tensile strength, major cause that Young's modulus is lower to be: 1. binder materials and additive can't be realized accurate process quantified controlling; 2. it is uncontrollable that gelatinization point, viscosity, concentration etc. influence the important glue in-process metrics of binder performance; 3. the tackiness agent production not science of preparing burden.
The tackiness agent staple that carton in the market adopts has W-Gum, water, sheet alkali, borax etc., because the not science and the precision of batching are not enough, causes the tackiness of tackiness agent can not satisfy the demand that carton is produced, and does not possess waterproof, moisture-proof function simultaneously.In the ordinary course of things, after making moist, every layer of paper separates automatically; Cause the water resistance of common Corrugated Box relatively poor thus, producing stacking after 40 days, ultimate compression strength obviously reduces; The pile layer does not reach design requirements, and the transportation under incompatibility wet weather, sea-freight and the refrigerated outlet environment.
China is manufacturing powerhouse, and production is also in occupation of critical role at home in the Chongqing City, and as the product of realizing protection, transportation, storage (refrigeration) and sale functions such as (comprising outlet), carton plays an important role.The product of numerous enterprises especially household electrical appliance, electronic product, food and medicine and precise electronic etc. is embodied in not only to the requirement of packed in cases that intensity is big, shock resistance is strong, shock-absorbing capacity is good, printing is attractive in appearance etc.; Require simultaneously that packed in cases product water resistance is strong, moistureproofness is high; Suit under moist, cold storage environment, to stack transportation, but also will meet country and foreign market demand carton product environment-friendly type, returnability and environmental protection such as pollution-free.The Chongqing City occupies consequence in national packed in cases industry, and the science and technology research and development level of carton state of the art and wrapped product is in national middle and upper reaches level, but because the restriction of self-technique, the carton product still can't satisfy above-mentioned requirements.The paper pack product of producing still is common Corrugated Box, and intensity, water tolerance mainly rely on the different material of employing to control and improve production cost height, and low, the poor water resistance of product adhesive performance.Market increases the increasing demand of the Corrugated Box tackiness agent that possesses high-strength tackiness enhanced water resistance.
(3) summary of the invention
The present invention has been mainly on the solution market key technical problems such as the ubiquitous tackiness of Corrugated Box tackiness agent is low, poor water resistance.Carry out scientific allocation from selection, the allotment of binder materials, make tackiness agent of the present invention possess technical superioritys such as high adhesion and enhanced water resistance, realize simultaneously improving working conditions, reduce cost, simplify purposes such as technology.
Task of the present invention realizes that through following embodiment concrete scheme is following:
One, the component of tackiness agent and content, raw material confirms
Change that the composition weight proportion is in the tackiness agent:
35 parts of treated starches, 360 parts in water, 7 parts in caustic soda, 3 parts of additives, said additive are Precondensed UreaFormaldehyde Resin ((CH2-N-CO-N-CH2)-), Z 150PH, medicine membrane resin and glue stablizer are specifically filled a prescription shown in table 1 in the accompanying drawing.The liquid stabilizer that is added is a glycol substance; The Pickering agent is to make through tackify material boric acid, borax and industrial sodium-chlor are mixed by 83: 5: 11 weight ratios.Through carrying out repeatedly formula test, optimum formula is: Z 150PH 4.4%, medicine membrane resin 0.025%, Pickering agent 2%, liquid stabilisers 0.9%, water surplus.
Two, the configuration technology of tackiness agent
Z 150PH of 1) prescription being weighed and medicine membrane resin are put into lixator and are dissolved;
2) reinforced water temperature is about 25 ℃, and in the raw material input dissolving trough inner water, the raw material surface presents half dissolved form rapidly, and particle is easy to mutual bonding formation block, the high more easy more hard bulk that becomes of the polymerization degree;
3) reinforced, keep temperature-stable, the abundant stirring 14-17 minute under the temperature conditions arranged; With beginning to heat up after the block dispersion that generates, dissolving is upgraded to about 90 ℃ in the groove, is up to 150 ℃ again; Handled 5 minutes; But prevent 160 ℃ of high temperature, heating means are directly in solution, to trim vapour, and the steam gauge pressure is 1.2kg/cm
2
4) stir on the following dissolving of 93 ℃ of temperature limits and all dissolve, regulate because the increment of steam condensate, add water to and begin to formulate concentration, be cooled to below 55 ℃, splash into stablizer while stirring until solid.
The tackiness agent that so makes both can use immediately, can deposit again, preferably used immediately.
(4) description of drawings
Table 1 is the water-fast alkali gelatinization of a high elastic coefficient modified starch compound resin tackiness agent development prescription
1 treated starch, 2 caustic soda, 3 water, 4 Precondensed UreaFormaldehyde Resins, 5 Z 150PH, 6 medicine membrane resins, 7 Pickering agent, 8 liquid stabilisers
(5) embodiment
Further specify enforcement of the present invention and main points with following instance.
Carrier:
1) water filling (summer 330kg, winter 350kg), Z 150PH (4.4%) that prescription is weighed and medicine membrane resin (0.025%) are put into lixator and are added starch 37kg again, stir 5 minutes;
