Abstract
The invention relates to an oily reverse/smooth hair nubuck resin for synthetic leather and its preparation method. The oily reverse/smooth hair nubuck resin is composed of modified polyurethane resin, toluene, isopropanol, and high-temperature fine nubuck powder. The oily reverse/smooth hair nubuck resin has good color development and leveling property, uniform pores after high-temperature foaming, obvious hair reversing/smoothing effect, wear and scratch resistance, strong fluff feeling, delicate touch sense of leather surface, and strong real leather effect.
Description
Technical field
The present invention relates to a kind of use for synthetic leather oiliness and fall along hair sheep bar resin and preparation method thereof, the use for synthetic leather oiliness that particularly is applied to synthetic leather rear section technique is fallen along hair sheep bar resin and preparation method thereof, belongs to innovative back segment material.
Background technology
At present, existing not ideal along color developing and the levelling property of hair sheep bar resin, particularly in the high temperature foaming process, length consuming time and abscess are inhomogeneous, and not obvious along the capillary effect fruit, the leather surface sense of touch is relatively poor.Therefore, need to provide a kind of improved along a hair sheep bar resin.
Summary of the invention
The purpose of this invention is to provide a kind of use for synthetic leather oiliness falls along hair sheep bar resin.
Use for synthetic leather oiliness of the present invention is fallen and is achieved through the following technical solutions along hair sheep bar resin:
Use for synthetic leather oiliness disclosed in this invention is fallen along hair sheep bar resin composed of the following components: modified polyurethane resin, toluene, Virahol and high-temperature fine sheep bar powder.
Take the gross weight of resin as benchmark, use for synthetic leather oiliness disclosed in this invention is fallen along the proportioning of each component of hair sheep bar resin as follows: modified polyurethane resin 45～50 weight parts, toluene 25～30 weight parts, Virahol 15～20 weight parts, high-temperature fine sheep bar powder 3～5 weight parts.
In one embodiment of the invention, the use for synthetic leather oiliness is fallen along the proportioning of each component of hair sheep bar resin as follows: modified polyurethane resin 45 weight parts, toluene 25 weight parts, Virahol 18 weight parts, high-temperature fine sheep bar powder 4 weight parts.
In another embodiment of the present invention, the use for synthetic leather oiliness is fallen along the proportioning of the component of hair sheep bar resin as follows: modified polyurethane resin 50 weight parts, toluene 30 weight parts, Virahol 15 weight parts, high-temperature fine sheep bar powder 5 weight parts.
In yet another embodiment of the present invention, the use for synthetic leather oiliness is fallen along the proportioning of each component of hair sheep bar resin as follows: modified polyurethane resin 48 weight parts, toluene 29 weight parts, Virahol 20 weight parts, high-temperature fine sheep bar powder 3 weight parts.
Another object of the present invention provides a kind of use for synthetic leather oiliness and falls along mao preparation method of sheep bar resin, comprises following steps:
1) high-temperature fine sheep bar powder, toluene, Virahol are stirred;
2) in step 1) add modified polyurethane in the mixture of gained, uniform stirring namely gets described use for synthetic leather oiliness and falls along a hair sheep bar resin.
Use for synthetic leather oiliness provided by the present invention is fallen and is clung among the preparation method of resin along the hair sheep, and the proportioning of each component is as follows: modified polyurethane resin 45～50 weight parts, toluene 25～30 weight parts, Virahol 15～20 weight parts, high-temperature fine sheep bar powder 3～5 weight parts.
In one embodiment of the invention, the use for synthetic leather oiliness is fallen and is all carried out at normal temperatures and pressures in steps along mao preparation method's of sheep bar resin a institute.
Because adopt above technical scheme, the present invention compared with prior art has following advantage:
1. use for synthetic leather oiliness of the present invention is little yellow liquid along a hair sheep bar resin, and good color developing and levelling property are arranged, and after the high temperature foaming, abscess is even, along the capillary effect fruit obviously, wear-resisting scratch resistance, velvet is strong, and the leather surface sense of touch is fine and smooth, and leather effect is strong.
2. oiliness is ep-type material along a hair sheep bar resin, meets the environmental protection standard of European Union;
3. form oiliness fall along each component of hair sheep bar resin mutually coordinate, acting in conjunction, make leather surface that unique velvet is arranged after the foaming, the sense of touch exquisiteness is comfortable, and is unique with the leather feel that this kind resin is made, and falls along the capillary effect fruit obviously, leather effect is strong, net effect is good;
4. this oiliness is fallen and use at existing synthetic leather production line along hair sheep bar resin, technique is simple, and after back segment was processed, 170 ℃～180 ℃ foaming got final product in three minutes.
