Description
Technical field
The invention belongs to nail production field, especially relate to a kind of gluing process preparing nail.
Background technology
In nail preparation process, nail is toughness and the intensity combination product of collection product, product globality in use and resistance to fracture is kept if want, will ensure that product has enough toughness while possessing higher-strength, but existing nail commercially all can not meet these two conditions simultaneously, determine mainly its adhesive glue in process of production of the toughness of nail and intensity, the glue that routine is used is seccotine, as PC seccotine, seccotine rises and solidifies, make the effect that it is hardening, the intensity of product can be ensured; Next be belong to adhesive one class neutral gum as A406 instant drying adhesive, it is by good adhesive effect.
Introduce a kind of adhesive polyurethane adhesive in the present invention, it mainly plays adhesive effect, can regulate the suppleness of product together with instant drying adhesive.
Summary of the invention
The object of this invention is to provide the gluing process of the preparation nail that a kind of technique simply, easily operates, ratio regulates well.
Technical scheme of the present invention is: a kind of gluing process preparing nail, and the glue of preparation nail comprises polyurethane adhesive, instant drying adhesive and seccotine successively, and often kind of glue percentage is by weight:
Polyurethane adhesive 27-33%
Instant drying adhesive 22-28%
Seccotine 42-48%
Preferably, often kind of glue percentage is by weight:
Polyurethane adhesive 30%
Instant drying adhesive 25%
Seccotine 45%
The step of above-mentioned glue point glue is utilized to be:
(1) preparation machine.By polyurethane adhesive, instant drying adhesive, seccotine puts into first glue bucket, second point glue bucket and thirdly glue bucket successively respectively;
(2) set point glue ratio.By regulating the adjusting device on point gum machine, i.e. the distance of adjusting screw(rod) and felt, and then the ratio of often kind of some glue is set;
(3) glue is put.After nail enters the first adjusting device, evenly after the upper polyurethane adhesive of point, next by the first drying unit, drying is carried out to the glue on nail surface; Then by the second adjusting device, the evenly upper instant drying adhesive of point, next by the second drying unit, carries out drying to the glue that nail surface has been put further; Finally by the 3rd adjusting device, the evenly upper seccotine of point, then by the 3rd drying unit, now, three layers of cementing bundle of point of nail, nail enters next process and processes.
Described adjusting device comprises mold, bed die and screw rod, the both sides that described mold lower surface is relative are respectively equipped with upper groove, felt is provided with in upper groove, upper screw rod through the upper surface of mold, and enters in upper groove and contacts with felt, and the upper surface of described bed die is provided with low groove, low groove and upper groove are parallel up and down, lower screw rod through the lower surface of bed die, and enters in low groove and contacts with felt
Being set to of screw rod: often rotate screw rod one circle, is equivalent to the some glue amount of minimizing 1%.
Illustrate: polyurethane adhesive is the glue containing urethano and NCO in strand, due to the isocyanates containing strong polarity and carbamate groups, there is very high reactivity, can cold curing, thus to metal, rubber, glass, etc. multiple material have excellent glueability.The backbone flexibility of polyurethane is fine, and its maximum feature is withstand shock vibrations and flexural fatigue, and peel strength is very high, and particularly resistance to low temperature is extremely excellent, is all widely used in every field.
The Main Ingredients and Appearance of instant drying adhesive is a-cyanoacrylate glue, mainly forms base-material+curing agent+filler+plasticizer+flexibilizer+diluent.It is a kind of one pack system, low viscosity, transparent, normal temperature rapid curing adhesive.Bonding wide, having good cementability to most material, is one of important room temperature setting adhesives kind.Weak point is that reaction speed is too fast, and resistance to water is poor, and fragility is large, and heatproof low (<70 DEG C), storage life is short, and durability is bad, therefore will add corresponding auxiliary agent when joining glue, is used for provisional bonding.Material of main part is specific cyanoacrylate, then adds some auxiliary substances as stabilizing agent, thickener, plasticizer, polymerization inhibitor etc.Should exclusion of water steam as far as possible when joining glue, it is little or air-locked that packing container also applies gas permeability.
The Main Ingredients and Appearance of seccotine is cyanoacrylate (C5H5NO2), and cyanoacrylate is a kind of acrylic resin, almost can Instant Adhesive (forming its most firmly chemical bond).The reaction trigger that it uniquely needs is the hydroxyl ion existed in water.Hydroxyl ion is easy to obtain, because almost any surface that you may want to bond object all can moisture containing at least trace, seccotine is the novel all-transparent solution glue of one-component, cold curing, easy to operate, have excellent water-fast, oil resistant, the characteristic of acid and alkali-resistance.
The advantage that the present invention has and good effect are: the gluing ratio of often kind of glue should reach standard-required (concrete ratio: 30%--25%--45%), glue process on three roads, no matter product is the higher standard that all can reach enterprise's defined from aspects such as degree of adhesion, color, line plate intensity and flatness.
