Abstract

The present invention discloses a composite agent and a gum preparing process for starch gum for a production line for making a corrugated board. Each composite agent comprises bentonite, borax, sepiolite, inorganic bentonite, urea, sodium perborate and sodium oxalate which are ground, uniformly mixed and respectively packed into a component A (main agent) and a component B (accessorial agent). The gum preparing process of the composite agent provided by the process, which is adopted, comprises the steps of hydrolysis, gelatinization, crosslinking, complexation, etc., wherein the component B (accessorial agent) is respectively added and gelatinized, and the component A (main agent) is added and carries out crosslinking and complexation. Starch gum prepared by the technical scheme provided by the process has the advantages of strong cementing capacity, quick dryness, stable storage, low cost, etc. The gum preparing process is simplified, heating preparing paste does not need, energy sources are saved, and gum production amount is enhanced. The gum preparing process is used for the production automation line of a corrugated board, and a driving speed can be enhanced 10 to 50 m/min.

Description

The preparation starch adhesive for corrugated board production line is with recombiner and adhesive-preparing technology

The present invention relates to corrugated cardboard with the preparing technical field, particularly corrugated cardboard of amylan with amylan with recombiner and adhesive-preparing technology.

China existing corrugated board production enterprise still adopts water glass (being commonly called as water glass) as binding agent, and the cardboard of its making exists defectives such as cohesive strength is poor, the accumulation of salt in the surface soil moisture absorption, and is yielding.Though and some enterprises use amylan as binding agent, but that its adhesive-preparing technology adopts is main, the traditional technology of carrier substep glue, defectives such as this traditional adhesive-preparing technology exists that complex procedures, the suitable marquis's property of prescription are poor, product viscosity instability, easily layering and precipitating, storage period be short.

One of purpose of the present invention provides a kind of preparation corrugated paper board production line with the amylan recombiner, to solve the weak point that existing preparation amylan raw material exists.

The technical scheme that adopts is for achieving the above object: the preparation corrugated paper board production line is with the amylan recombiner, it is characterized in that every part of recombiner is made up of the wilkinite of 30-70%, the borax of 12.5-20%, the sepiolite of 0-15%, the inorganic bentonite of 0-60%, the urea of 4-10%, the Sodium peroxoborate of 3-5%, the sodium oxalate of 0.5-1%, wherein wilkinite, borax, sepiolite are through the A component (host) that grinds, mixing is packaged into recombiner; Inorganic bentonite, urea, Sodium peroxoborate, sodium oxalate are through grinding, and mixing is packaged into the B component (paying agent) of recombiner.

Two of purpose of the present invention provides a kind of adhesive-preparing technology for preparing corrugated paper board production line with amylan, to solve the weak point of existing master, carrier substep adhesive-preparing technology.

The technical scheme that adopts is for achieving the above object: a kind of adhesive-preparing technology for preparing the fluting board printed line with amylan is characterized in that its technology is made up of following steps:

(1) hydrolysis: get 100 parts of starch and add 80% of 505-535 part water, in reactor, carry out abundant hydrolysis and get starch solution;

(2) gelatinization: get 2.4-3.4 part caustic soda (content＞95%) and add 10% of 505-535 part water and be mixed with alkali lye, then the alkali lye for preparing and the B component (paying agent) of recombiner are added in the reactor in the lump, starch solution is carried out gelatinization;

(3) crosslinked, complexing: the water of 505-535 part remaining 10% and the A component (host) of recombiner are added in the reactor in the lump, make the starch solution of gelatinization carry out crosslinked, complexing and can make amylan;

When stating technology on the implementation, alkali, water consumption and the room temperature relation of being inversely proportional to.

Adopt corrugated paper board production line that technical scheme provided by the invention produces with amylan have that viscosifying power is strong, dry fast, shelf-stable, advantage such as with low cost, and oversimplified adhesive-preparing technology, need not heat paste producing, saved the energy, improve gum yield, be used for the corrugated board production automation line, can improve speed of a motor vehicle 10-50m/min.

Table 1 is the amylan formula table of the embodiment of the invention 2.

Embodiment 1: the preparation corrugated paper board production line is with the amylan recombiner, its every part recombiner is made up of 35% wilkinite, 14% borax, 6% sepiolite, 37% inorganic bentonite, 4% urea, 3.2% Sodium peroxoborate, 0.8% sodium oxalate, wherein wilkinite, borax, sepiolite are through grinding, and mixing is packaged into the A component (host) of recombiner; Inorganic bentonite, urea, Sodium peroxoborate, sodium oxalate are through grinding, and mixing is packaged into the B component (paying agent) of recombiner.

Embodiment 2: a kind of adhesive-preparing technology for preparing the fluting board printed line with amylan, form by following steps:

(1) hydrolysis: get 100 parts of kg starch and add 80% (404-428kg) of 505-535kg water, in reactor, carry out abundant hydrolysis and get starch solution;

(2) gelatinization: 10% (50.5-53.5kg) that gets 2.4-3.4kg caustic soda (content＞95%) and add the water of 505-535kg is mixed with alkali lye, B component (paying agent) with the alkali lye for preparing and recombiner adds in the reactor in the lump then, and starch solution is carried out gelatinization;

(3) crosslinked, complexing: the water and the recombiner A component (host) of 505-535kg residue 10% (50.5-53.5kg) are added in the reactor in the lump, make the starch solution of gelatinization carry out crosslinked, complexing and can make amylan;

When stating technology on the implementation, alkali, water consumption and the room temperature relation of being inversely proportional to (seeing Table 1).
