[0006] 本发明的目的是提供一种水性手套的生产方法,不采用在聚氨酯树脂中添加有害的化学物质,而是采用水性PU树脂生产手套的方法,解决现有技术中生产出来的手套带有毒性、污染环境、工艺麻烦的技术问题。 [0006] The object of the present invention is to provide a method for producing an aqueous gloves, without using harmful chemical substance is added in the polyurethane resin, instead of using an aqueous PU resin production gloves, to solve the prior art gloves produced with technical problems toxic, polluting the environment, the process cumbersome.

[0007] 本发明的目的是通过以下技术方案实现的:[0008] 一种水性手套生产方法,包括:步骤SI,将浸有凝固剂的手套芯套在手模上的步骤;步骤S2,将套在手模上的手套浸入浆料中,使手套表面上形成一层涂层的步骤,其中,PU浆料为水性聚氨酯树脂,或由97%〜99. 9%的水性聚氨酯树脂与0. 1%〜3%的水性增稠剂配置而成的混合浆料;步骤S3,对形成PU涂层的手套进行烘干或风干的步骤。 [0007] The object of the present invention is achieved by the following technical solution: [0008] an aqueous glove production method, comprising the steps of: the SI, the glove impregnated with a step on the core sleeve coagulant Shoumo; step S2, Shoumo set in the glove was immersed in the slurry, the step of forming a coating on the surface of the glove, wherein, PU slurry is an aqueous urethane resin, or a 97% ~99 9% of an aqueous polyurethane resin and 0. 1% ~ 3% of a thickening agent configured by mixing an aqueous slurry; step S3, the PU coating on the glove form of the step of drying or dried.

[0009] 作为优选方案,在上述的步骤S2中,手套芯在温度为0〜50°C的I3U浆料中浸溃0. I〜30s时间。 [0009] As a preferred embodiment, the above-described step S2, the glove I3U core slurry temperature is 0~50 ° C in the immersed crushed 0. I~30s time. 更具体的,手套芯在温度为14.9-25. 5°C的I3U浆料中浸溃0. 5〜10.6s时间。 More specifically, the glove I3U core slurry temperature is 14.9-25. 5 ° C the impregnated crushed 0. 5~10.6s time.

[0010] 涂层的厚度,时间越长,厚度越厚,时间越短,厚度越薄,手套过厚,舒适度比较差,触感比较差,涂层过薄,手套不耐用;温度过高,会对PU浆料稳定性产生不利影响,过低,会影响I3U浆料的流动性;通过大量的实验发现,在在温度为9. 8-25. 50C的I3U浆料中浸溃0. I〜10. 6s时间,能够充分保证I3U浆料的稳定性和流动性同时,涂层厚度可以很好地控制在0. 2-1_之间,其手感和舒适度非常好,也保证了耐性用。 [0010] The longer the coating thickness, the time, as the thickness, the shorter the time, the thinner the thickness, too thick gloves, relatively poor comfort, feel relatively poor, the coating is too thin, durable gloves; temperature is too high, PU adversely affect the stability of the slurry, too, will affect the flow of the slurry I3U; found through a lot of experiments, the temperature of the slurry at I3U 9. 8-25 50C is impregnated collapse 0. I. ~10. 6s time, we can fully guarantee the stability and fluidity of the slurry I3U while the coating thickness can be well controlled between 0.5 2-1_, which is very good feel and comfort, but also to ensure the tolerance use.

[0011 ] 涂层边缘的整齐性,温度过高,流动性好,涂层边缘的整齐性高,但是PU浆料稳定性不好;温度过低,流动性不好,涂层边缘的整齐性差;时间长,有助于涂层边缘整齐,时间过短,边缘整齐性差;在工艺中,要综合平衡温度和时间的关系,确保PU浆料稳定性、流动性和涂层边缘的整齐性都取得很好地效果,研究表明在温度为14. 90C -36. I°C的I3U浆料中浸溃0. 5〜16. 7s时间是最合适的范围。 [0011] The uniformity of the coating edge, high temperature, good fluidity, high uniformity of the coating edge, but PU poor slurry stability; temperature is too low, poor fluidity, uniformity of the coating edge difference ; long time, the coating helps neat edge time is too short, neat edge poor; in the process, and comprehensive relationship between equilibrium temperature and time to ensure PU slurry stability, flowability and uniformity of the coating edges are to obtain good results, studies show that a temperature of the slurry at I3U 14. 90C -36. I ° C were immersed collapse 0. 5~16. 7s time is the most appropriate range.

[0012] 在综合涂层边缘的整齐性和涂层的厚度的考虑,优选在温度为14. 9-25. 5°C的I3U衆料中浸溃0. 5〜10. 6s时间。 [0012] In consideration of the thickness and uniformity of the coating edge of the coating layer is integrated, preferably at a temperature of public I3U 14. 9-25. 5 ° C in the feedstock impregnation 0. 5~10. 6s time.

[0013] 作为优选方案,上述混合浆料由99%〜99. 7%的水性聚氨酯树脂与0. 3%〜1%的水性增稠剂配置而成。 [0013] As a preferred embodiment, the mixed slurry of 99% ~99 7% of an aqueous polyurethane resin and configured by 0.3% ~ 1% aqueous thickening agent. 更具体的,所述PU浆料还包括进行发泡工艺,其中,发泡前与发泡后的发泡体积比例为1:3至I: I. 05。 More specifically, the PU slurry further comprises a foaming process, wherein the volume ratio of the foamed foaming and after foaming is between 1: 3 I: I. 05.

[0014] 上述的步骤S2后还包括:步骤S211,以45-135°的方向向I3U涂层喷射盐的步骤,其中,所述的盐直径小于1mm。 [0014] After the above step S2 further comprising: a step S211, the direction of 45-135 ° to the coating injection step salt I3U, wherein said salt of a diameter less than 1mm. 所述步骤S211具体步骤为:在温度为0〜50°C,以不低于0. 005克/平方厘米/秒的速度向涂层面喷盐0. 5秒以上,所述的盐直径小于1mm。 Step S211 is the specific steps: at a temperature of 0~50 ° C, speed of not less than 0.005 g / cm / sec to the coating surface of the above salt spray 0.5 seconds, less than a diameter of said salts 1mm.

[0015] 本发明通过喷盐在手套表面形成了磨砂效果。 [0015] The present invention results in formation of a matte surface of the glove by a salt spray. 为了在手套上形成磨砂效果,需要在PU涂层上形成一层均匀的盐层,且通过控制盐量达到形成磨砂的要求。 In order to form a matte effect on the glove, a salt necessary to form a uniform coating layer on the PU, and reaches the requirements matte formed by controlling the salt. 因此喷盐过程中,需要在PU涂层将要凝固但还未凝固的时候向表面喷盐,但是其条件控制非常重要;比如通过温度确保PU涂层将要凝固但还未凝固的状态,通过喷盐时间和喷盐速度,来控制喷盐的多少,使PU表面形成一层均匀的盐层。 Thus during the salt spray, the PU coating will need to be solidified but not yet solidified when sprayed to the surface of the salt, but it is important to control conditions; PU coated, such as by ensuring the temperature to be solidified state, but not yet coagulated by salt spray salt spray time and speed, to control how much of the salt spray the PU surface to form a uniform layer of salt. 通过对喷盐温度、速度和时间的综合研究发现,在温度为0〜50°C下,以不低于0. 005克/平方厘米/秒的速度向涂层面喷盐0. 5秒以上,能够满足各种要求。 Salt spray to the coating surface by salt spray temperature, speed and time of the comprehensive study found that at a temperature of 0~50 ° C, of ​​not less than 0.005 g / cm2 / sec or more than 0.5 seconds to meet various requirements. PU表面经过喷盐处理后,待其洗尽干燥后,PU表面会呈现一种磨砂的效果,而这种磨砂的表面对于手套的作用是十分明显的,例如涂层表面磨砂后,会形成一种强烈的视觉舒适感,长时间接触可以有效地减轻视觉疲劳,而且涂层显的相当有质感。 PU surface after the salt spray treatment, until washed out and dried, the surface will show the effect of one kind PU frosted, which frosted surface and the role of the glove is very clear, for example, the matte surface coating, will form a species strong visual comfort, prolonged exposure can effectively reduce visual fatigue, and the coating is quite significant texture. 当然,在手套的使用过程中,涂层表面经磨砂处理后,手套的止滑性是普通涂层不可比拟的,特别是接触表面带有油类的物件,这一点对于手套的最大使用群体一厂矿企业来说显的尤为重要。 Of course, during use of the glove, the coating surface after grinding treatment, an ordinary glove slip coating incomparable, especially oils with a contact surface of the object, which is the maximum use of glove for a group factories and enterprises is most importance.

[0016] 另外需要注意的是,本发明优选以55-75°或105-125°的方向向I3U涂层喷射盐,在这个角度范围内,其不仅形成的磨砂效果非常好,而且在进行水洗的时候非常容易把盐洗掉。 [0016] Also note that the present invention is preferably 55-75 °, or in a direction to 105-125 ° I3U injection salt coating, within this angle range, which not only forms a matte effect is very good, and the water washing when very easy to wash off the salt.

[0017] 所述的盐选自离子化合物,其在喷盐条件下为直径小于Imm的固体小颗粒。 [0017] The ionic salt is selected from compound as a solid small particles of diameter less than Imm under salt spray conditions. [0018] 作为优选方案,上述的步骤S2后还包括:步骤S22,对PU涂层进一步进行凝固处理。 [0018] As a preferred embodiment, after the above steps S2 further comprising: a step S22, the coagulation of PU coating further processing.

[0019] 前述的凝固处理方法:将凝固剂喷向PU涂层或将浸好涂层的手套浸入凝固剂中的任一种方法。 [0019] The above-described solidification method: A method according to any of the coagulant in the coagulant sprayed PU coating or dip coating gloves dipped well.

[0020] 作为优选方案,在烘干前,对形成涂层的手套进行水洗的步骤。 [0020] As a preferred embodiment, prior to drying, the step of forming the coating of the glove is washed with water.

[0021] 由于采用了以上的技术方案,本发明可以达到以下有益效果:采用不添加化学溶剂的水性聚氨酯树脂(水性PU树脂),无毒性;不采用有毒的化学有机溶剂,因此可以不进行水洗的工艺,工艺简单,浸溃PU涂层的时间短,提高了生产效率。 [0021] With the above technical solution, the present invention can achieve the following advantageous effects: The aqueous polyurethane resin (an aqueous PU resin) without addition of chemical solvents, non-toxic; do not use toxic chemicals organic solvent, and therefore may not be washed with water process, the process is simple, short-impregnated PU coating time and improve production efficiency.
