Description

一种热塑性聚氨酯人造革 A kind of thermoplastic polyurethane artificial leather

技术领域 technical field

本发明涉及一种人造革的配方及其制造方法,尤其是指一种全环保型热塑性聚氨酯(TPU,Thermoplastic Polyurethane)人造革及其压延制造法。The invention relates to a formula of artificial leather and a manufacturing method thereof, in particular to an all-environmental-friendly thermoplastic polyurethane (TPU, Thermoplastic Polyurethane) artificial leather and a calendering manufacturing method thereof.

背景技术 Background technique

传统的人造革的生产,主要以PU合成皮及PVC合成皮为主体,用于制造PU合成皮的主要原料为含高溶剂的PU树脂及稀释溶剂,用于制造PVC合成皮的主要原料为PVC粉及液体可塑剂,增塑剂采用邻苯二甲酸酯类,制造方法为涂布法、贴合法、吹膜法或T-模流延法等。传统的人造革的配方和制造方法有以下缺点:The production of traditional artificial leather mainly uses PU synthetic leather and PVC synthetic leather as the main body. The main raw materials used to manufacture PU synthetic leather are PU resin and dilution solvent containing high solvent. The main raw material used to manufacture PVC synthetic leather is PVC powder. And liquid plasticizer, the plasticizer adopts phthalates, and the manufacturing method is coating method, pasting method, blown film method or T-die casting method, etc. The formula and manufacturing method of traditional artificial leather have the following disadvantages:

(1)当以PU合成皮作为主体,采用涂布法制造人造革时,由于涂布工艺中需要对经凝聚、水洗后的半成品进行干燥处理,PU树脂配方中所用的溶剂在干燥过程中将衍生成为废水、废气,污染环境;并且,PU合成皮的耐水解性较差,如欲改善其耐水解性能时,其剥离强度及表面耐磨耗强度等性能相对变差,尤其当底布采用尼龙织布时,剥离强度在0.5Kg/3cm以下,使用于高摩擦撞击用途场合时,其表面耐磨耗及剥离强度品质难于符合市场要求,实用性不大。(1) When PU synthetic leather is used as the main body and the coating method is used to manufacture artificial leather, since the semi-finished product after condensation and water washing needs to be dried in the coating process, the solvent used in the PU resin formula will be derived during the drying process. Become waste water, waste gas, and pollute the environment; moreover, the hydrolysis resistance of PU synthetic leather is poor. If you want to improve its hydrolysis resistance, its peel strength and surface abrasion resistance will be relatively poor, especially when the base fabric is made of nylon. When weaving, the peel strength is less than 0.5Kg/3cm. When used in high friction and impact applications, the surface wear resistance and peel strength quality are difficult to meet market requirements, and the practicability is not great.

(2)当以PVC合成皮作为主体,采用贴合法制造人造革时,在混炼压延过程中,由于长时间在高温开放系统中进行操作,易产生粉尘和可塑剂挥发废气,对环境污染很大;并且,PVC制品垃圾焚化时会产生有毒气体戴奥辛(dioxin)、氯气及重金属微粒;PVC合成皮的低温耐屈折及耐冲击性能差,若欲改善其耐低温性能则表面极易出现可塑剂或添加助剂吐出的异常现象,(2) When PVC synthetic leather is used as the main body and lamination method is used to manufacture artificial leather, in the process of kneading and calendering, due to long-term operation in a high-temperature open system, dust and plasticizer volatilization waste gas are easily generated, which is very polluting to the environment In addition, when PVC products are incinerated, toxic gases such as dioxin, chlorine, and heavy metal particles will be produced; PVC synthetic leather has poor low-temperature bending resistance and impact resistance. The abnormal phenomenon of adding additives to spit out,

(3)邻苯二甲酸酯类为有毒试剂,作为增塑剂,使得制成的人造革中含有毒配方,应用于日常生活中,危害人们的身体健康。(3) Phthalate esters are toxic reagents. As plasticizers, the manufactured artificial leather contains toxic formulas, which are used in daily life and endanger people's health.

因此,为了解决上述的种种问题,本发明提供了一种以热塑性聚氨酯作为主料的环保无毒、可降解的人造革配方,以及用于制造该种人造革的方法。Therefore, in order to solve the above-mentioned various problems, the present invention provides an environmentally friendly, non-toxic and degradable artificial leather formulation using thermoplastic polyurethane as a main ingredient, and a method for manufacturing the artificial leather.

与现有技术相比较,本发明一种热塑性聚氨酯人造革采用了热塑性聚氨酯弹性体树脂作为主料,取代了传统的人造革主料PU合成皮或PVC合成皮,掺合丙烯酸树脂、增塑剂、分散剂、填充材料等制成,其中,增塑剂由无毒的多元醇衍生物替代了有毒的邻苯二甲酸酯类,使得制成的人造革具有环保无毒、可降解的特性。Compared with the prior art, a thermoplastic polyurethane artificial leather of the present invention adopts thermoplastic polyurethane elastomer resin as the main material, replaces the traditional artificial leather main material PU synthetic leather or PVC synthetic leather, blends acrylic resin, plasticizer, dispersion It is made of non-toxic polyol derivatives instead of toxic phthalates, so that the artificial leather is environmentally friendly, non-toxic and degradable.

另外,本发明采用压延法制备热塑性聚氨酯人造革,可应用常规的压延生产线,不需要用吹膜或T-模流延生产线,这样,可令原本用于聚氨乙烯(PVC)人造革生产的压延设备不会因PVC基于环保因素而市场收缩所导致投资损失,且压延机不须作任何机械更改,此生产方法可令TPU人造革的生产成本大大降低,令市场更接受TPU作为环保料使用。在制备工艺中,主料聚氨酯树脂与各种添加剂辅料在高速搅拌机同时加入,不需预先加热,也不需预先造粒,通过控制添加剂比例及混炼搅拌时的温度,应用丙烯酸树脂、分散剂高分子脂肪酸酯以及硬脂酸降低生产过程中原料分子间的磨擦,并降低熔融体的熔融温度,从而提高热稳定性,且防止熔融体粘在金属轮面上,降低机器负荷,减低电力消耗。In addition, the present invention adopts calendering method to prepare thermoplastic polyurethane artificial leather, can apply conventional calendering production line, does not need to use blown film or T-die casting production line, like this, can make the calendering equipment originally used in the production of polyurethane (PVC) artificial leather There will be no investment loss due to the market shrinkage of PVC due to environmental protection factors, and the calender does not need any mechanical changes.
