Description
Technical field
The invention belongs to sheet fabrication field of adhesive technology, and in particular to a kind of powder without aldehyde sheet material glue and its prepare and
Application method.
Background technology
Traditional sheet material glue " three urea formaldehyde glue " and newly research and develop without aldehyde glue, be all liquid glue substantially, solid content is general
It is all relatively low, typically only 30~40%, water content has reached 60~70%.Because moisture is high, and is liquid condition, typically
Packed using Plastic Drum or metal drum, packaging and cost of transportation are all high, and packaging process is complicated, in-convenience in use.Also,
Liquid sheet material glue is restricted using region, it is necessary to is founded the factory, is sold nearby nearby, significantly limit sheet material glue field
Development.
In order to reduce packaging and cost of transportation, there is research to attempt that moisture is separated or dried, sheet material glue is turned into solid, but
Sheet material glue formaldehyde prepared by this operating method is serious, it is impossible to use.
The content of the invention
The technical problem to be solved in the present invention is：Conventional panels glue is liquid, inconvenience packaging and transport, production cost height etc.
Problem.
The present invention solve technical problem technical scheme be：A kind of powder is provided without aldehyde sheet material glue and its preparation and user
Method.
The present invention provides a kind of powder without aldehyde sheet material glue, and its composition includes：By weight percentage, white dextrin 50~
60%th, bean cake powder 5~10%, butadiene-styrene latex powder 5~7%, methenamine 6~8%, borax 5~7%, blood meal 10~15%, fibre
Dimension element 1~3%, lime 8~10%.
It is preferred that, above-mentioned powder is without in aldehyde sheet material glue, and its composition includes：By weight percentage, white dextrin 50%, dregs of beans
Powder 10%, butadiene-styrene latex powder 6%, methenamine 6%, borax 6%, blood meal 10%, cellulose 2%, lime 10%.
Present invention also offers a kind of preparation method of the above-mentioned powder without aldehyde sheet material glue, comprise the following steps：Raw material is pressed
Percentage by weight is weighed, and is well mixed.
Present invention also offers a kind of application method of the above-mentioned powder without aldehyde sheet material glue, powder is added when in use without aldehyde plate
The clear water of 2.5~3 times of material glue weight, is mixed thoroughly.
Beneficial effects of the present invention are：The invention provides a kind of powder without aldehyde sheet material glue and its preparation and application,
The sheet material glue is using white dextrin as primary raw material, while it is aided with bean cake powder, butadiene-styrene latex powder and blood meal, and in methenamine, boron
In the presence of sand and lime, hydrophobic substance is generated, therefore sheet material glue bond ability of the present invention and water-resistant capacity are all relatively strong, enhancing
The moisture retention of adhesives, also functions to very big effect to the ageing during plate adhesion.It is prepared by sheet material glue of the present invention
Method is simple, easy to use, and packaging and the more existing sheet material glue of cost of transportation reduce by more than 15 times, with important economic benefit.
Embodiment
The invention provides a kind of powder without aldehyde sheet material glue, its composition includes：By weight percentage, white dextrin 50~
60%th, bean cake powder 5~10%, butadiene-styrene latex powder 5~7%, methenamine 6~8%, borax 5~7%, blood meal 10~15%, fibre
Dimension element 1~3%, lime 8~10%.
It is preferred that, above-mentioned powder is without in aldehyde sheet material glue, and its composition includes：By weight percentage, white dextrin 50%, dregs of beans
Powder 10%, butadiene-styrene latex powder 6%, methenamine 6%, borax 6%, blood meal 10%, cellulose 2%, lime 10%.
Present invention also offers a kind of preparation method of the above-mentioned powder without aldehyde sheet material glue, comprise the following steps：Raw material is pressed
Percentage by weight is weighed, and is well mixed.
Present invention also offers a kind of application method of the above-mentioned powder without aldehyde sheet material glue, powder is added when in use without aldehyde plate
The clear water of 2.5~3 times of material glue weight, is mixed thoroughly.
White dextrin also known as corn dextrin；No. CAS is 9004~53~9, and molecular formula is C18H32O16, it is a kind of cementability
With all preferable binding material of wetability, but itself poor water resistance.White dextrin is rich in protein, and the present invention has been especially added with black Lip river
Tropine and borax, in the basic conditions, dextrin can strengthen sheet material glue with methenamine and borax reaction generation hydrophobic substance
Water resistance.In the present invention, lime is used to provide alkaline environment for the reaction of dextrin and methenamine and borax.The present invention
In, white dextrin is as core adhesives, and its addition is particularly important, and white dextrin addition is too low, adhesive property and ageing property
Requirement can be reached, therefore, white dextrin is advisable with 50~60%.
Further, in order to strengthen the caking property and water resistance of sheet material glue, the present invention also added 5~10% bean cake powder
With 10~15% blood meal, they are macro-molecular protein with white dextrin, can be reacted with methenamine and borax, raw
Into the strong hydrophobic substance of caking property, the caking property and water resistance of sheet material glue further enhancing.Bean cake powder and blood meal adding proportion
It is unsuitable too high, in case cost is too high or sheet material glue is had variegated.
In addition, the present invention also added butadiene-styrene latex powder, itself has stronger adhesive property and high-temperature resistant water performance,
Addition 5~7% butadiene-styrene latex powder be can significantly the adhesive property of sheet material glue and formation glued membrane water resistance.
The present invention also added 1~3% cellulose, and cellulose is combined with remaining binding material, can strengthen bonding material
The moisture retention of material, plays a significantly greater role to the ageing during plate adhesion.
Explanation is further explained to the embodiment of the present invention below by embodiment, but does not indicate that and sends out this
Bright protection domain is limited in described in embodiment in scope.
