Description
Technical field
The present invention relates to a kind of nail glue, especially a kind of nail glue for improving nail hardness belongs to binder technology neck
Domain.
Background technique
Nail is that a kind of woodwork that regularly arranged single nail adhesive or other means bonding is got up is used
Nail.Nail is placed into special nailing gun, using electricity or compressed air as power, by percussion inject plank, plastics or
In other composite materials.The advantages that nailing gun makes to follow closely uniform force, consistent since its is high-efficient, easy to use and answered extensively
With, and the nail as its " bullet ", also just there is a large amount of demand.
Nail influences nail product quality key raw material during producing is exactly nail glue, and nail glue is a kind of molten
Dosage form adhesive, by the quick-drying volatilization film forming gluing of solvent.Nail glue is the most fundamental to be required to be to have enough adhesive strengths,
Nail can be made to connect together, while also to have hardness appropriate, be able to maintain flexibility appropriate.Existing nail glue
Lack enough stiffnesses, and is affected by seasonal temperature variation.
A kind of metal nail adhesive and preparation method thereof, raw material group are described in patent document CN201410019607.4
The carboxyl vinyl chloride-vinyl acetate resin 8~16% for being about 34000 as average molecular weight, the carboxyl chlorine vinegar tree that average molecular weight is about 27000
Rouge 0~8%, nitrile rubber 3.5~5.5%, epoxy resin 1.5~6.5%, methyl hexahydrophthalic anhydride 2~4%, aluminium acetylacetonate
0.01~1%, methyl acetate 0~40%, acetone 30~77% is made by pretreatment, mixing, heating, stirring.The nail glue
With good adhesive property, but there are the insufficient defect of hardness, the only glue is used cooperatively with other glue, could both guarantee
With good adhesive property, and enough intensity is provided, form a kind of firm Rational structure in the flexible outside in an inside, protected
Hinder the stable production of manufacturing enterprise, keeps preferable yield rate.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of metal nail glue and preparation method thereof, can be improved metal
The hardness of nail glue, when being used cooperatively with other metal nail glue have good compatibility and complementarity, improve nail at
Product rate.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of metal nail glue, raw material and its weight percent be solid material 14~22%, liquid solvent 78~86%,
The solid material includes nitrocellulose, plasticizer and anti-aging agent, and the liquid solvent includes alcohols solvent.
Technical solution of the present invention further improvement lies in that: liquid solvent further includes esters solvent and ketones solvent.
Technical solution of the present invention further improvement lies in that: in solid the weight percent of each ingredient be nitrocellulose 80
~99%, plasticizer 0.5~19% and anti-aging agent 0.5~3%.
Technical solution of the present invention further improvement lies in that: in liquid solvent the weight percent of each ingredient be alcohols solvent
75~99%, esters solvent≤20% and ketones solvent≤5%.
Technical solution of the present invention further improvement lies in that: metal nail adhesiveness be 4500~5500 centipoises.
The invention also discloses a kind of preparation methods of metal nail glue, comprising the following steps:
A. blender is added in the liquid solvent measured, opens stirring；
B. nitrocellulose, plasticizer and anti-aging agent are sequentially added in whipping process；
C. after mixing time T, finished product viscosity and solid content are detected.
Technical solution of the present invention further improvement lies in that: mixing speed be 60~90 revs/min.
Technical solution of the present invention further improvement lies in that: mixing time T be 2 hours.
By adopting the above-described technical solution, the technological progress achieved by the present invention is:
A kind of metal nail glue provided by the invention and preparation method thereof, can be improved the hardness of metal nail glue, with it
There is good compatibility and complementarity when its metal nail glue is used cooperatively, improve nail yield rate.
Raw material of the invention includes solid material and liquid solvent, and solid material includes nitrocellulose, plasticizer and prevents
Old agent, when the weight percent of solid material is 14~22%, liquid solvent weight percent is 78~86%, resulting row
Adhesiveness is followed closely up to 4500~5500 centipoises, hardness is moderate, is able to maintain preferable nail yield rate.
The main material that the present invention uses is nitrocellulose, and nitrocellulose has very high hardness, and softening point is very high.
When nitrocellulose accounts for 80~99% in solid material, solvent only needs suitably volatilization (partially to wave
Hair, sufficiently volatilizees without waiting for solvent), it will be able to embody good stiffness.It is used cooperatively with the insufficient nail glue of hardness,
Adhesive strength can be not only improved, and hardness can be improved.
The present invention joined plasticizer in the feed, since nitrocellulose has very high hardness, in order to avoid nail
Glue stiffness is excessively high and leads to be easy breakage, and present invention adds 0.5~19% plasticizer.The adjustable solid material of plasticizer
The hardness of material improves yield rate to reach suitable hardness requirement during guarantee is used cooperatively with other nail glue.
Liquid solvent of the invention includes alcohols solvent, and alcohols solvent has stronger volatility, and metal nail glue leans on alcohol
The quick-drying of class solvent, which is volatilized, to form a film, to play the role of gluing.The solid material of metal nail glue of the present invention is nitrocellulose
Element primarily serves the effect for improving hardness, needs with the biggish nail glue of adhesion strength with the use of can be only achieved preferable effect
Fruit, still, the poor compatibility of the solid material in solid material and the biggish nail glue of adhesion strength in the present invention, in alcohols
Increase esters, ketones solvent in solvent, metal nail glue and the biggish nail glue glue-line of adhesion strength of the invention can be improved
Compatibility, improve adhesive force, two kinds of glue can form one, form common adhesive layer, without departing from or layering.
Specific embodiment
Here is certain specific embodiments of the invention, to be described in further detail.
A kind of metal nail glue, raw material and its weight percent be solid material 14~22%, liquid solvent 78~86%,
The solid material includes nitrocellulose, plasticizer and anti-aging agent, and the liquid solvent includes alcohols solvent.
The weight percent of each ingredient is nitrocellulose 80~99%, plasticizer 0.5~19% and prevents in solid material
Old agent 0.5~3%.
The weight percent of each ingredient is alcohols solvent 75~100%, esters solvent≤20% and ketone in liquid solvent
Solvent≤5%.
Metal nail adhesiveness is 4500~5500 centipoises.

(becoming B glue) is that the function of A glue is supplemented, and can increase hardness.Specifically when in use, nail production needs gluing three times
(1), A glue, usage amount 20-40% are used for the first time；
(2), A glue, usage amount 20-40% are used second；
(3), B glue, usage amount 20-40% are used for the third time；
(4), optimal use method, first time dosage are greater than second of dosage, and third time dosage universal law is three points
One of, worker can adjust usage amount according to the variation in season.
The problem of metal nail glue of the invention is able to solve stiffness is the defect for compensating A colloidality energy, is used in combination with A glue.
A glue, B glue are used cooperatively, i.e. the guarantee good adhesive property of A glue, and provide enough intensity, and it is flexible outer to form an inside
A kind of firm Rational structure in portion.In addition, A, B glue are used in combination, the variation of temperature can be eliminated, the variation in season makes nail
The influence of performance ensures the stable production of manufacturing enterprise, keeps preferable yield rate (yield rate > 95%).
