Abstract
The invention discloses a process for producing low-smoke-amount flame-retardant leather. The process comprises the following steps: preparing a base cloth; automatically feeding the cloth by virtue of an unreeling machine, and preheating the base cloth in a baking device; coating a polyurethane adhesive layer on the outer layer of the base cloth to form an adhesive layer; coating an auxiliary layer which is a smoke suppression flame retardant on the adhesive layer; coating a PVC foaming layer on the auxiliary layer; coating a surface treating agent layer on the PVC foaming layer to form a PVC surface layer after the surface treating agent is dried and cured; and coating an oily treating agent layer on the surface of the PVC surface layer to form an oily treating layer. Auxiliaries in the auxiliary layer are magnesium hydroxide, aluminum hydroxide, zinc borate and the like, which can be used for playing a certain role in retarding flame, improving smoke density when artificial leather is burnt, and reducing generation of toxic substances.
Description
Technical field
The present invention relates to a kind of production technology of low-smoke flame-retardant leather.
Background technology
Dermatine is also imitation leather or rubber, is the general name of the artificial materials such as PVC and PU.It is on woven fabric base or nonwoven fabric base, formed by the foaming such as PVC and PU of various different formulations or overlay film processing and fabricating, can require be processed into according to varying strength, abrasion resistance, cold-resistant degree and color, gloss, floral designs etc., have that designs and varieties are various, water resistance good, not care about one's appearance is neat, the high feature cheap relative to corium with price of utilization rate.
Now, dermatine has been manufactured in a large number and has been applied in and comprised in clothing, shoes, furniture and vehicle material.The manufacture of dermatine is generally use to mix the Nonwovens of forming as base cloth by general fiber, superfine fibre or general fiber and superfine fibre, and polyurethane resin constituent is inserted on this scrim surfaces, after impose attrition process or embossing processing or impose laminating processing with release liners coating polyurethane resin, and form surface there is the cladding of elasticity and corium lines.
Be provided with solvent layer in dermatine, cause oxidant layer, levelling oxidant layer, thickening oxidant layer or surfactant layer etc., so a large amount of toxic gases or compound can be produced during the combustion product of imitation leather material, the compound of such as chlorine, chlorine, containing nitrogen compound etc., these materials are all harmful to the health of people.
Summary of the invention
The object of the invention is to overcome above deficiency, a kind of production technology of low-smoke flame-retardant leather of smoke density when improving burning is provided.
Object of the present invention is achieved through the following technical solutions: a kind of production technology of low-smoke flame-retardant leather, comprises the following steps:
A, prepare base cloth; Cloth realizes automatic charging by unreeling machine, and this base cloth is put into apparatus for baking the pre-heat treatment;
B, at base cloth skin coating one deck polyurethane binder, form adhesive layer;
C, on adhesive layer, apply one deck auxiliary agent layer, auxiliary agent layer is smoke inhibition fire retardant;
D, on auxiliary agent layer, apply one deck PVC foam layer;
E, on PVC foam layer, apply layer of surface finishing agent, after described surface conditioning agent is solid, forms a PVC surface layer;
F, apply one deck oily treating agent on the surface of PVC surface layer, form oiliness processing layer.
Further improvement of the present invention is: in steps A, base cloth is directly prepared from by meeting embryo at the bottom of the cloth of furniture, handbag or clothing leather demand or wet type.
Further improvement of the present invention is: in steps A, base cloth comprises one of embryo or foaming bottom embryo at the bottom of bed of cloth, wet type.
Further improvement of the present invention is: contact worn processing process in wiping mode to the top layer face on base cloth.
Further improvement of the present invention is: surface conditioning agent take synthetic resin as raw material.
Further improvement of the present invention is: surface conditioning agent is wiping finishing agent or wipes burnt finishing agent.
Further improvement of the present invention is: smoke inhibition fire retardant is made up of magnesium hydroxide, aluminium hydroxide, Firebrake ZB, and the weight portion of magnesium hydroxide, aluminium hydroxide, Firebrake ZB is respectively: 40-45%, 35-40%, 15-20%.
The present invention compared with prior art has the following advantages:
Auxiliary agent in auxiliary agent layer is magnesium hydroxide, aluminium hydroxide, Firebrake ZB etc., and these auxiliary agents can not only play certain flame retardant effect, can also improving the smoke density of dermatine when burning, reducing the generation of noxious material.
