Description

A kind of degradable PVC decorative artificial leather of Environment-friendlywear-resistant wear-resistant
Technical field
The invention belongs to artificial leather manufacturing fields, and in particular to a kind of degradable PVC decorative artificial leather of Environment-friendlywear-resistant wear-resistant.
Background technique
In terms of the theory of ecological artificial synthetic leather includes following four: first is that not brought to environment during the manufacturing It is dirty；Second is that harmless during being processed into leather goods；Third is that it is harmless in use process, do not generate pollution to environment； Fourth is that it is biodegradable, and catabolite will not cause new pollution to environment.Currently, we mention ecological synthetic leather, people It is emphasised that product is harmless in use, pollution is not generated to environment, this is only one of ecological synthetic leather Aspect, if it is considered that other three elements: greenization during the manufacturing, leather goods processing greenization, castoff regenerative or It is biodegradable, it may be said that there are no the ecological synthetic leathers in really consciousness for we.Currently, synthetic leather enterprise mostly use greatly it is molten Dosage form slurry, material not environment friendly, manufacturing process non-green.The exploitation of ecological artificial synthetic leather must use clean manufacturing Technology.Low-carbon, low energy consumption, zero-emission or it is few discharge, recycle be clearer production technology core content.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of degradable PVC decorative artificial leather of Environment-friendlywear-resistant wear-resistant is provided.
A kind of degradable PVC decorative artificial leather of Environment-friendlywear-resistant wear-resistant, is made: PVC resin powder 120-150 of the raw material of following component Part, 12-15 parts of vinyl chloride-vinyl acetate resin, 18-22 parts of diacetyl epoxy soybean olein, polycaprolactone-based polyurethane elastomer 8-12 Part, 0.9-1.2 parts of foaming agent, 15-18 parts of epoxidized soybean oil, 22-35 parts attapulgite modified, 1 ~ 2 part of lubricant, silicone master batch 1 ~ 2 part, 1 ~ 2 part of stabilizer, 1 ~ 2 part of pigment；
It is described attapulgite modified modified using following steps:
(1), attapulgite is crushed, crosses 60 meshes, the oxalic acid solution immersion treatment 1-2h for the use of mass fraction being then 5%, so Afterwards, it is washed using clear water to neutrality；
(2), the dodecane that the attapulgite for handling step (1) well is 2.5% using 10 times of attapulgite weight of mass fraction Base benzene sulfonic acid sodium salt immersion treatment 15-20min is handled using ultrasonic oscillation in soaking process；
(3), the attapulgite that step (2) is handled well is dried at 150-180 DEG C, is obtained attapulgite modified.
The preparation process of artificial leather the following steps are included:
(1) will through weighing PVC resin powder, vinyl chloride-vinyl acetate resin, polycaprolactone-based polyurethane elastomer, lubricant, silicone master batch, Stabilizer is put into high-speed kneading machine, and epoxidized soybean oil is then added, and stirs 15-20min, it is big to add diacetyl epoxy Soya-bean oil acid glyceride after being stirred for 5 ~ 10min, is added pigment, is stirred for 3min, attapulgite modified and foaming agent is added, And stir 3 ~ 5min；When mixing temperature is to 90 ~ 100 DEG C, reaches mixture and be held in the hand and do not moisten in the heart, it is soft uniformly, have bullet Property, can blowing, obtain just mixing；
(2) first mixing is put into mixer, 3.5 ~ 4min of mixing, to electric current, steady, dough mixing to dough is sent without fecula Enter and send material to plastics processing mill；
(3) refining modeling is packaged turnup on first plastics processing mill and is sent several times to whole plastics processing mill, and refining modeling to material volume sends out glutinous, translucent no light When, be cut into diameter be in 10 ~ 15cm material volume or be split into tablet, sent with conveyer belt to calender, obtain calendering slurry；
(4) calendering slurry is bonded the Bu Ji of preheated open-width processing, be entirely introduced into, between lower roll, preheated surface layer film Enter baking oven after fitting part and semi-finished product obtained above leather are bonded again to be plasticized, foam at 220 DEG C, after cooling and shaping, Obtain the degradable PVC decorative artificial leather of Environment-friendlywear-resistant wear-resistant.
The refining modeling process conditions are just 180 DEG C of roller temperature, 5 ~ 7mm of roll spacing of refining, eventually 185 DEG C of roller temperature of refining, 3 ~ 5mm of roll spacing.
The polycaprolactone-based polyurethane elastomer is the diphenylmethane diisocyanate that NCO/OH molar ratio is 1.05:1 0.01 ~ 0.08% score of gross weight is added in ester, hexamethylene diisocyanate and polycaprolactone diols under the conditions of ultrasonic 20kHz Stannous octoate, be stirred to react at 60 DEG C and solidify the obtained polymer elastomer of crosslinking for 24 hours.
The foaming agent is 4,4'- oxobenzenesulfonyl hydrazide.
The Bu Ji is 155 ~ 175g/m of grammes per square metre2, 0.55 ~ 0.65mm of thickness, 1.55 ~ 1.65m of breadth, warp direction stretching load >=300N, broadwise tensile load >=300N, through to elongation at break >=10%, broadwise elongation at break >=15%, through negative to tearing Lotus >=20N, broadwise tearing load >=20N, through to the woven single side raising twill with broadwise percent thermal shrinkage >=3%.
Beneficial effects of the present invention:
Internally plasticized vinyl chloride-vinyl acetate resin itself is introduced, increases the intensity of artificial leather, reduces the dosage of plasticizer, avoid small molecule Migration, while increasing the toughness of artificial leather, bright property.Artificial leather solubility property and the rubber cement mobile performance being made into are excellent, people Fabricate-leather has good toughness, and durable Rao Quxing and shows excellent adhesiveness to all paint films at fabulous anti-tear characteristic, It can increase attapulgite modified intermolecular force, reduce cost, plasticizing agent migration resisting can promote the intensity of artificial leather and resistance to Mill property.
Introducing and the good polycaprolactone based elastomeric of polyvinyl chloride compatibility, have shape memory function, artificial leather shape Shape retention property is good, resistance to wrinkle, folding.Polycaprolactone based polyurethanes, there is biological degradability, utilize the recycling of artificial leather.And It and is that artificial leather has excellent hot property, mechanical performance, shape memory function and biological property.At room temperature when recovery of shape Between few, and no cytotoxicity.
The present invention has the advantage that compared with prior art
The degradable PVC decorative artificial leather of a kind of Environment-friendlywear-resistant wear-resistant provided by the invention, changes the blending of PVC resin powder by the present invention Property, the artificial leather resistance to migration of preparation greatly reinforced, through the invention the coordinated effect between each ingredient, is made Artificial leather not only there is preferable mechanical performance, compared to common artificial leather, the present inventor's fabricate-leather tensile load improves 22% Left and right, tearing load improve 40% or so, also have preferable folding fastness ageing properties, the leather passed through 32000 times it is resistance to Fastness experiment is rolled over, ageing properties experimental result is not crack.Test discovery, mechanical property of the present invention are greatly improved, and increase Add fire-retardant degradable ability, enhances wearability, and moisture absorption breathes freely, cleans smooth comfortable, antibacterial and deodouring, resistance to migration It is good.
