Abstract
The invention discloses highlight ultra-bright PVC (Polyvinyl Chloride) luggage leather. The highlight ultra-bright PVC luggage leather is prepared by coating a highlight sizing agent in a hanging manner on PVC artificial leather, wherein the highlight sizing agent is formed by mixing components in parts by weight as follows: 70-80 parts of non-benzene diluent, 6-14 parts of HDI (Hexamethylene Diisocyanate) tripolymer, 75-85 parts of hydroxy acrylic resin, and 2-6 parts of color paste. The PVC artificial leather disclosed by the invention not only has excellent mechanical performances, but also has a highlight characteristic.
Description
Technical field
The invention belongs to artificial leather and make the field, be specifically related to a kind of high brightness PVC artificial leather.
Background technology
Artificial leather is widely used in the fields such as case and bag, sofa, along with the raising of people life, quality and incrustation is required more and more higher, and women has particularly become fashion to the pursuit of beautiful, bright-coloured fashionable dress satchel.The annual output total value of Large-scale enterprises is about 100,000,000,000 on the present domestic case and bag industry, and increases progressively with annual 10000000000 to 20,000,000,000 sales volume.And when the luggage leather of most of Gao Guang is processed on the surface on the market, adopt cheap processing slurry, generally all use the TDI addition product, this class Gao Guangge protect light colour retention, yellowing resistance, and durability improve grade all lower, and free TDI toxicity is larger, and one or two months turn to be yellow with regard to delustering.
Summary of the invention
The purpose of this invention is to provide a kind of PVC artificial leather that possesses high brightness function and physical and chemical performance and pliability excellence.
Purpose of the present invention can reach by following measures:
A kind of high brightness type PVC artificial leather, it adopts the high brightness slurry that the PVC artificial leather is hung to be coated with and processes and make, described high brightness slurry is mixed by the component of following weight parts: 70～80 parts of benzene-free thinners, 6～14 parts of HDI tripolymers, 75～85 parts of Hydroxylated acrylic resins, 2～6 parts of mill bases.
High brightness slurry of the present invention is preferably mixed by the component of following weight parts: 72～75 parts of benzene-free thinners, 9～11 parts of HDI tripolymers, 78～81 parts of Hydroxylated acrylic resins, 3～5 parts of mill bases.Most preferred, the high brightness slurry is mixed by the component of following weight parts: 73 parts of benzene-free thinners, 10 parts of HDI tripolymers, 80 parts of Hydroxylated acrylic resins, 3～5 parts of mill bases.
Adopt the high brightness slurry to the PVC artificial leather hang be coated with processing after, lower dry in 20 ℃～65 ℃ again.As drying or dry normal temperature or 60 ℃.
PVC artificial leather among the present invention can adopt existing various PVC artificial leathers, preferably, this PVC artificial leather utilizes the artificial leather slurry to adopt rolling process to be prepared from, described artificial leather slurry is made into by the component of following weight portion: 100 parts in polyvinyl chloride resin powder, 10～30 parts of epoxidized soybean oils, 2～20 parts of look cakes, 3～7 parts of stabilizing agent and blowing agents, 10～50 parts of fillers.
In the PVC artificial leather, stabilizing agent is potassium zinc stabilizer, barium zinc stabilizer or PVC compound stabilizer, and described blowing agent is Celogen Az or the mixture that contains Celogen Az, and described filler is powdered whiting.Described rolling process be each raw material with rigid slurry after 100～150 ℃ of lower high-speed stirred in 145～155 ℃ of lower banburyings, obtain rigid slurry; Base material is in 140～160 ℃ of lower upper PU slurries, then is incorporated into described rigid slurry to enter 4-roll calender to press down Yangjing in 160～190 ℃ whole, the processing of foaming under 160～180 ℃ at last.
High brightness PVC artificial leather of the present invention, the epidermis face is processed at the bottom of this PVC artificial leather, adopts to hang to be coated with technique, makes the high brightness slurry coat leather surface.
The present invention adopts the super excellent HDI tripolymer slurry of the lower various aspects of performance of toxicity to substitute traditional TDI addition product, under the mutual synergy of each component, make the surface treatment of its PVC artificial leather preferably, thereby make the case and bag of making beautiful durable, especially physical and chemical performance is excellent, and pliability is excellent.
The specific embodiment
Embodiment 1
Each raw material and the weight portion proportioning thereof of high brightness slurry are: benzene-free thinner 73, HDI tripolymer 10, Hydroxylated acrylic resin 80, mill base 3～5.
Each raw material of end skin and the weight portion proportioning thereof of high brightness PVC luggage leather are as follows: 100 parts in polyvinyl chloride resin powder, 25 parts of epoxidized soybean oils, 8 parts of look cakes, 3 parts of barium zinc stabilizers, 2 parts of Celogen Azs, 20 parts of 2000 order calcium carbonate superfine powders.
Each material passages through which vital energy circulates of end skin after will measure by end skin batching rushes in the feeder input homogenizer, and temperature is controlled at 100-150 ℃ fully after the stirring, enters banbury, and temperature is controlled at (160 ℃) banburying number minute; In addition, after base material (various cloth) open-width, upper PU slurry (150 ℃), the sufficient material of banburying is combined with the base material of upper PU slurry, enter two and roll mill (160 ℃) and open refining, enter again 4-roll calender (temperature 160-190 ℃) calendering smooth after, be cooled to normal temperature curling, enter again foamed printing machine (160-180 ℃) foaming and be pressed into various decorative patterns, make end skin for subsequent use.
After the high brightness slurry fully mixes, adopt to hang to be coated with technique, epidermis face of the above-mentioned end is hung be coated with processing, be equipped with different colours (mill base) according to customer requirement, normal temperature or 60 degree dry or dry in hanging stove, fully dry and comfortable rear rolling, the packing that gets product warehouse-in.
