Abstract
The invention discloses environment-friendly synthetic sofa leather and a preparation method of the synthetic sofa leather. The synthetic sofa leather is prepared by dipping waterborne polyurethane size, wherein the waterborne polyurethane size is formulated by waterborne polyurethane resin, a defoamer, a thickener, a flatting agent, an organic silicon drying lubricant, a drier and a cross-linking agent. The environment-friendly synthetic sofa leather is produced by the environment-friendly material waterborne polyurethane resin. The product is low in cost, pure ecological and environment-friendly, and can meet the requirements of low-carbon life.
Description
Technical field
The invention belongs to the synthetic leather field, be specifically related to synthetic sofa artificial leather of a kind of environment-friendly type and preparation method thereof.
Background technology
Natural leather is owing to having good natural characteristic and be widely used in by people and produce commodity and industrial goods, but along with the growth of world population, human demand multiplication to leather, a limited number of natural leathers can not satisfy this demand of people already.For solving this contradiction, scientists namely begin one's study decades ago exploit person fabricate-leather, synthetic leather are to remedy the deficiency of natural leather.Facts have proved at present, every premium properties of synthetic leather is that natural leather can't replace, and analyzes from market both domestic and external, and synthetic leather has also replaced the natural leather of inadequate resource in a large number.Adopt artificial leather and synthetic leather to make the decoration of case and bag, clothes, footwear, vehicle and furniture, day by day obtain affirming of market, its range of application is wide, and quantity is big, more than the kind, is that traditional natural leather can't satisfy.But often there are the shortcomings such as with an organic solvent not environmental protection of contaminated environment of production process, wearing and tearing are very fast, folding resistance is poor in existing synthetic leather.
Summary of the invention
The objective of the invention is on the basis of existing technology, provide a kind of environment-friendly type to synthesize sofa artificial leather.
Another object of the present invention provides the preparation method of the synthetic sofa artificial leather of a kind of above-mentioned environment-friendly type.
Purpose of the present invention can reach by following measures:
A kind of environment-friendly type is synthesized sofa artificial leather, and this synthetic sofa artificial leather adopts steep water based polyurethane slurry to be prepared from, and described aqueous polyurethane slurry is made into by the component of following weight portion:
Wherein waterborne polyurethane resin further is the synthetic aqueous polyurethane of polyester-type dihydroxylic alcohols.Its mechanical property is than the height of polyether-type, its modulus and to draw high intensity all better.
Crosslinking agent is divided into three kinds of low temperature, middle temperature, high temperature, under different temperatures cross-linking reaction occurs respectively, has improved that water-base polyurethane material is water-fast, chemically-resistant solvent, the poor shortcoming of resistance to elevated temperatures.Crosslinking agent among the present invention is selected from warm crosslinking agent among DT-100 crosslinking agent, the EVA, XR-100 crosslinking agent, DT-100W high-temperature cross-linking agent.
Defoamer among the present invention is selected from polyether-modified polysiloxane defoamer.
Described thickener is selected from CA-908 aqueous polyurethane thickener, K-800 aqueous polyurethane thickener or CA-902 aqueous polyurethane thickener.
Described levelling agent is selected from long brightness BNK-LK600 levelling agent, D-3000 aqueous polyurethane levelling agent or RA1103 aqueous polyurethane levelling agent.。
The dried lubrication prescription of described organosilicon is selected from the dried lubrication prescription of MOLYKOTE 557 organosilicons or the dried lubrication prescription of DOW CORNING 557 organosilicons.
Between defoamer among the present invention, thickener, levelling agent, the dried lubrication prescription of organosilicon with and with the synergy that cooperatively interacts of waterborne polyurethane resin, can improve in the aqueous polyurethane process of producing product because of molecular weight and surface tension than the low various disadvantages that easily produce of solvent-borne type.
Drier among the present invention is dibutyl tin laurate.
The invention also discloses a kind of preparation method of above-mentioned synthetic sofa artificial leather: first base fabric is carried out the starching preliminary treatment, the fabricbase that obtains in preliminary treatment after the oven dry floods at least one deck aqueous polyurethane slurry and in the foaming furnace drying in oven, be coated with again intumescent coating, 110～130 ℃ of lower oven dry, paint at last or the post processing that adds lustre to, and get final product.
Wherein the starching preliminary treatment refers to that coating waterborne polyurethane resin at base fabric seals pulp, so that the adhesive force of increase and coating mainly is starching on scutcher, again 55～65 ℃ of lower oven dry rollings; Described intumescent coating is the waterborne polyurethane resin layer.
Beneficial effect of the present invention:
The synthetic sofa artificial leather of environment-friendly type of the present invention adopts environmentally friendly material waterborne polyurethane resin to produce, and the low-carbon (LC) needs of life has been satisfied in low, the pure ecology of its cost, environmental protection.
