Description

A kind of tapioca (flour) tackiness agent and preparation method thereof

Technical field

The present invention relates to a kind of tapioca (flour) tackiness agent and preparation method thereof, belong to technical field of fine chemical preparations.

Background technology

At present the oxidized starch adhesive that uses has not excellent properties such as burn into does not get damp again, price is low, be used as the substitute of water glass as the tackiness agent of corrugated cardboard, but because amylan exists that seasoning speed is slow, bond strength is low and problem such as package stability difference, numerous medium and small carton factories still uses water glass as tackiness agent at present, in order to address the above problem, research department has done a large amount of work to the improvement of amylan performance both at home and abroad, developed various amylans, mainly can be divided three classes: the macromolecular compound commixed type; Packing type and graft reaction type, though performances such as the oxidized starch glue seasoning speed after the modification and bond strength are improved significantly, it is more that production cost also improves, still difficulty is accepted by medium and small carton factory.Therefore, for satisfying the carton industry to the demand of the amylan of high strength, low price, the present invention is raw material with the tapioca (flour) of China's abundant, and the relation in conjunction with the distribution of starch molecule amount, hydroxyl etc. provides a kind of tapioca (flour) tackiness agent and preparation method thereof,

Summary of the invention

The tapioca (flour) tackiness agent of characteristics such as purpose of the present invention will provide a kind of bonding strength big exactly, and seasoning speed is fast, price is low, the technology making is simple, environment friendly and pollution-free.

The present invention is achieved through the following technical solutions: it is characterized in that this tapioca (flour) tackiness agent mainly by: tapioca (flour), oxygenant, catalyzer, paste agent, ten water Sodium Tetraboratees, siccative, Whitfield's ointment, defoamer, water etc. are formed.

A kind of tapioca (flour) tackiness agent by its weight part is: tapioca (flour) 100～150; Oxygenant 1～3; Catalyzer 0.2～0.6; Paste agent 3.0～6.0; Ten water Sodium Tetraboratees 1.0～3.0; Siccative 1.0～3.0; Whitfield's ointment 0.1～0.2; Defoamer 0.1～0.2; Water 450～550 is formed.

A kind of tapioca (flour) tackiness agent, its preparation method is:

The tapioca (flour) that measures is mixed, mixes well with water, elimination impurity, filtrate putting into has the interlayer reactor of electric mixer and thermometer, start agitator and be heated to 60 ℃, constant temperature 5min adds oxygenant and catalyzer, oxidative degradation 60min under constantly stirring, add paste agent, complexing agent (ten water Sodium Tetraboratees) then, make its abundant gelatinization, complexing 30min, add siccative, defoamer at last, stir, discharging behind the 30min gets final product.

Embodiment

1, accurately takes by weighing tapioca (flour) 100% by its weight fraction; Oxygenant 1.5; Catalyzer 0.5; Paste agent 5.0; Ten water Sodium Tetraboratees 2.0; Siccative 1.5; Whitfield's ointment 0.1; Defoamer 0.1; Water 500, standby.

2, preparation method:

The tapioca (flour) that measures is mixed, mixes well with water, elimination impurity, filtrate putting into has the interlayer reactor of electric mixer and thermometer, start agitator and be heated to 60 ℃, constant temperature 5min adds oxygenant and catalyzer, oxidative degradation 60min under constantly stirring, add paste agent, complexing agent (ten water Sodium Tetraboratees) then, make its abundant gelatinization, complexing 30min, add siccative, defoamer at last, stir, discharging behind the 30min gets final product.

Claims (3)

1. tapioca (flour) tackiness agent and preparation method thereof, this tapioca (flour) tackiness agent mainly by: tapioca (flour), oxygenant, catalyzer, paste agent, ten water Sodium Tetraboratees, siccative, Whitfield's ointment, defoamer, water etc. are formed.

2. according to right 1 described a kind of tapioca (flour) tackiness agent and preparation method thereof, by its weight part be: tapioca (flour) 100～150; Oxygenant 1～3; Catalyzer 0.2～0.6; Paste agent 3.0～6.0; Ten water Sodium Tetraboratees 1.0～3.0; Siccative 1.0～3.0; Whitfield's ointment 0.1～0.2; Defoamer 0.1～0.2; Water 450～550 is formed.

3. according to right 1,2 described a kind of tapioca (flour) tackiness agent, its preparation method is:

The tapioca (flour) that measures is mixed, mixes well with water, elimination impurity, filtrate putting into has the interlayer reactor of electric mixer and thermometer, start agitator and be heated to 60 ℃, constant temperature 5min adds oxygenant and catalyzer, oxidative degradation 60min under constantly stirring, add paste agent, complexing agent (ten water Sodium Tetraboratees) then, make its abundant gelatinization, complexing 30min, add siccative, defoamer at last, stir, discharging behind the 30min gets final product.
