Abstract
The invention discloses a water-borne polyurethane coating agent containing superfine down fiber-polylactic acid microspheres. The superfine down fiber-polylactic acid microspheres are prepared by the following steps of treating down fibers into superfine fibers with high surface activity and high thermal stability; mixing the superfine fibers with a polylactic acid solution, wherein the superfine fibers can adsorb the polylactic acid solution by using good adsorbability of the superfine fibers; subsequently, separating out the polylactic acid by using absolute ethyl alcohol serving as a poor solvent, thus obtaining composite microspheres. The composite microspheres have air and moisture permeability of the down fibers and biocompatibility of the polylactic acid; by using the composite microspheres, the defect that superfine down fibers easily absorb moisture is overcome, the moisture and air permeability of a traditional polyurethane coating can be effectively improved, a coating with flexibility, skin friendliness, and bacteria and mildew resistance is obtained, and use experience of fabric is remarkably improved; in addition, the coating can be biodegraded and recycled.

Technical field
The present invention relates to fabric coating finishing agent technical field, particularly relate to a kind of Aqueous Polyurethane Coating Agent containing ultra-fine down fiber-polylactic acid microsphere.
Background technology
Fabric coating finishing agent is called for short coating agent, is a kind of macromolecular compound thin film coating fabric face, in order to improve the style of fabric, feel and outward appearance etc., greatly improves the surcharge of textile.Aqueous Polyurethane Coating Agent is the environment-friendly coating agent that a class is important, it has elastic excellent, soft, the advantages such as wear-resisting solvent resistant, but its poisture-penetrability is poor, the dress having a strong impact on fabric is experienced, and production cost is high, along with the lifting of the market demand, research waterproof and breathable class environment-friendly polyurethane textile coating agent is particularly important." preparation of fibroin/Moisture-permeable Waterproof Polyurethane Coating and application thereof " literary composition utilizes fibroin to be modified polyurethane processing, effectively raise the moisture permeable effect of coating agent, but the hydrophobicity of fibroin is poor, along with the resistance to water of the raising coated film of fibroin mass fraction can be deteriorated, and the production cost of fibroin is higher, is unfavorable for large-scale production.
China is eider down big producing country, annual production leads and bounds ahead of other countries, eider down is the natural protein material of the amino acid peptide chain structure of a kind of many groups, crude protein content accounts for more than the 80% of whole eider down, the fluffy softness of its structure, warmth retention property is remarkable, possess good hygroscopicity and biocompatibility, but the research and utilization in terms of its utilization of resources is still in the rough machined level of raw material, in addition to a small amount of warming packing material of conduct is for clothing and bedding, some is used for sports goods, artware and the reinforcing material of composite, major part is all by as offal treatment, cause the substantial amounts of wasting of resources.Eider down is superior to fibroin in terms of moisture-penetrable ventilated property and resistance to water, if can effectively be introduced in polyurethane coating agent by eider down, it will obtain the coating agent possessing excellent comprehensive performance, improves the economic worth of fabric.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of Aqueous Polyurethane Coating Agent containing ultra-fine down fiber-polylactic acid microsphere.
The present invention is achieved by the following technical solutions:
A kind of Aqueous Polyurethane Coating Agent containing ultra-fine down fiber-polylactic acid microsphere, this coating agent is prepared by the raw material of following weight portion: solid content is the aqueous polyurethane emulsion 30-50 of 30-50%, ultra-fine down fiber-polylactic acid microsphere 1-5, dispersant 0.1, aqueous defoamer 0.1, deionized water 10-50.
The preparation method of described ultra-fine down fiber-polylactic acid microsphere is:
(1) by eider down through remove impurity, sterilize, clean, be dried after shear through high-speed shearing machine and to pulverize, cross 625-800 mesh sieve, subsequently sieving is put in fiberizer, using dehydrated alcohol as abrasive media defibrination, it is dried under the conditions of 60-80 DEG C after grinding 2-5h, makes ultra-fine down fiber；
(2) polylactic acid is dissolved in dichloromethane, it is configured to the solution that concentration is 5-10%, it is subsequently added the ultra-fine down fiber of step (1) gained, dehydrated alcohol is added after ultrasonic agitation dispersion 20-30min, high-speed stirred mixing 1-2h, solution left standstill layering subsequently, remove the supernatant, product is spray-dried after washing 2-3 time, obtains described ultra-fine down fiber-polylactic acid microsphere.
In described step (2), polylactic acid is 1:1 with the weight ratio of ultra-fine down fiber, and described PLA solution is 5-10:1 with the volume ratio of dehydrated alcohol.
Described a kind of preparation method containing the Aqueous Polyurethane Coating Agent of ultra-fine down fiber-polylactic acid microsphere is: by after each raw material stirring mix homogeneously and get final product.
Down fiber is processed into the superfine fibre with high surface and high thermal stability by the present invention, and it is mixed with PLA solution, its good adsorptivity can adsorb PLA solution, followed by poor solvent dehydrated alcohol, polylactic acid is separated out, thus obtain complex microsphere, this complex microsphere possesses breathable moisture permeability and the polylactic acid biocompatibility of down fiber, improve the defect of the easy moisture absorption of ultra-fine down fiber, it can effectively improve the moisture-penetrable ventilated property of conventional urethane coating, obtain pliable and tough pro-skin, the coating of antibacterial anti-mildew, significantly improve fabric experience, and this eluding biodegradable, can be recycled.
Detailed description of the invention
This embodiment coating agent is prepared by the raw material of following weight portion: solid content is the aqueous polyurethane emulsion 30 of 30%, ultra-fine down fiber polylactic acid microsphere 1, dispersant 0.1, aqueous defoamer 0.1, deionized water 10.
The preparation method of the most ultra-fine down fiber-polylactic acid microsphere is:
