【摘要】：UV涂料具有節(jié)省能源、不產(chǎn)生揮發(fā)性有機(jī)物、固化速度快、顏色鮮艷等優(yōu)點(diǎn),是環(huán)保材料領(lǐng)域的研究熱點(diǎn)。與傳統(tǒng)的紡織涂料印花工藝相比,紫外光固化技術(shù)適合于個性化紡織品的快速定制,在電子商務(wù)和個性化體驗(yàn)實(shí)體門店具有良好的市場前景。本文的研究目的在于制備分散穩(wěn)定的紡織UV涂料,并研究涂料在紡織上的應(yīng)用性能。首先研究了紡織UV涂料各組分對分散穩(wěn)定性、黏度和表面張力的影響。然后重點(diǎn)討論了UV涂料固化速度的影響因素。最后對紡織UV涂料的透明性、附著力、著色性能、摩擦牢度、斷裂強(qiáng)力等性能做了細(xì)致的表征。主要研究內(nèi)容和結(jié)論如下:為了提高UV固化涂料的分散穩(wěn)定性,探討7種單體和4種低聚物對UV固化涂料耐熱穩(wěn)定性和離心穩(wěn)定性的影響。用粒徑、吸光度和離心穩(wěn)定性來表征實(shí)驗(yàn)結(jié)果。結(jié)果表明:用單體EOEOEA、NPGDA和TMPTA,6201制備的UV固化涂料熱儲前后粒徑變化較小,熱儲吸光度穩(wěn)定性在95%以上,離心穩(wěn)定性在85%以上,可用來制備穩(wěn)定性高的UV固化涂料。UV固化涂料的各組分對其粘度、表面張力、固化速度都產(chǎn)生了不同的影響。單體對UV固化涂料的粘度、表面張力、固化速度影響都很大,隨著單體官能團(tuán)的增加,UV固化涂料的粘度、表面張力變大,固化速度加快。環(huán)氧類低聚物6104-80所制備的UV固化涂料粘度最小,隨著低聚物用量的增加,UV固化涂料的粘度變大。低聚物對UV固化涂料的表面張力影響較小。環(huán)氧類低聚物的固化速度比聚氨酯類低聚物的快,隨著聚氨酯類低聚物官能度的增加,固化速度加快。引發(fā)劑對UV固化涂料的粘度影響很小,對固化速度起決定性作用,固化速度的快慢為:369ITXBPDETX907TPO1173184EDB。隨著引發(fā)劑用量的增加,固化時間迅速減短,飽和用量為7%。研究了不同種類單體、低聚物、引發(fā)劑及低聚物用量和色漿質(zhì)量分?jǐn)?shù)對UV固化涂料透明性的影響。結(jié)果表明:TMTPA的透光率最低,IBOA的透光率最高。聚氨酯類低聚物比環(huán)氧類低聚物的透明性好,6201的透光率最高。9種引發(fā)劑中,ITX的透光率最低,907的透光率最高。隨著低聚物和色漿用量的增加,UV固化涂料的透光性明顯下降。探究了UV固化涂料組分對附著力、織物著色性能、摩擦牢度、斷裂強(qiáng)力的影響。三官能團(tuán)單體TMTPA、低聚物6201的附著力最好,隨著低聚物用量的增加,附著力減弱。雙官能團(tuán)單體TPGDA、NPGDA、HDDA和PDDA的K/S值最大,單官能團(tuán)單體EOEOEA和IBOA的K/S值次之,三官能團(tuán)單體TMPTA的K/S值最小。低聚物對K/S值的影響為6201聚氨酯丙烯酸酯6104-806318,隨著低聚物用量的增加,織物的K/S值先增大后變小,低聚物用量為30%時,K/S值最大。隨著色漿用量的增加,K/S值增大,當(dāng)色漿用量超過9%時,K/S值不再增加,反而有所下降。著色織物的濕摩擦牢度比干摩擦牢度好,隨著單體官能團(tuán)的增多,摩擦牢度變好。低聚物6104-80和6318的干濕摩擦牢度最好,達(dá)到5級。與原織物相比,UV固化涂料所著色的織物斷裂強(qiáng)力基本都增加,斷裂伸長均有所下降。
[Abstract]:Along with saving energy, does not produce volatile organic compounds, fast curing speed, bright color and other advantages, is a hotspot in the field of environmental protection materials. Compared with the traditional technology of textile printing, rapid customization of UV curing technology for personalized textiles, with good market prospects in e-commerce and personalized experience of physical stores. The purpose of this paper is to prepare stable dispersion of textile UV coatings, application performance and study of coating in the textile. Firstly, textile UV coating components on dispersion stability, effect of viscosity and surface tension. Then discusses the factors influencing the curing speed. Finally, transparency of textile UV coating adhesion, coloring performance. Rubbing fastness, tear strength and other properties to do a detailed characterization. The main research contents and conclusions are as follows: in order to improve the dispersion stability of UV curing coatings The qualitative effects of 7 monomers and oligomers of 4 kinds of UV curing coatings thermal stability and centrifugal stability. With the particle size, the absorbance and centrifugal stability was characterized. The results show: with the monomer EOEOEA, NPGDA and TMPTA before and after UV curing coatings prepared by thermal storage 6201 particle size change is small, heat storage stability of absorbance at 95% or more, the centrifugal stability in more than 85%, can be used to the preparation of high stability UV curing coatings of.UV curing coatings on the viscosity, surface tension, had the different influence of curing rate. The viscosity of monomer of UV curing coating surface tension, curing speed have great influence, with the increase the functional monomers, UV curing coating viscosity, surface tension becomes larger, curing speed. Epoxy oligomer 6104-80 prepared by UV curing coating viscosity minimum, with the increase of oligomer content, UV curing coating viscosity The surface tension of UV oligomers. Curing coatings have little influence. The curing rate of epoxy oligomer than polyurethane oligomer, with the increase of polyurethane oligomer functionality, curing speed. Effect of initiator agent on the viscosity of UV curing coatings is very small, the curing speed plays a decisive role, curing speed is 369ITXBPDETX907TPO1173184EDB.: with the increase of the amount of the initiator, the curing time quickly short oligomers of different saturation dosage of monomer, 7%., initiator and oligomer content and paste concentration on UV curing coating transparent effect. The results show that the transmittance of TMTPA IBOA the lowest, highest light transmittance than polyurethane oligomer. Epoxy oligomer has good transparency, light transmission rate of 6201 the highest.9 initiator in ITX, the transmittance of the lowest 907 of the highest light transmittance. With the oligomer and paste with The increase in the amount of light transmittance of UV curing coatings decreased significantly. To explore the UV curing coating composition on adhesion, fabric coloring performance, rubbing fastness, breaking strength. The influence of three functional monomer TMTPA, adhesion 6201 oligomer best, with the increase of oligomer content, adhesion decreased. Double functional monomer TPGDA. NPGDA, HDDA, PDDA and K/S value of the largest single functional monomer EOEOEA and IBOA K/S is the second, three functional monomer TMPTA. The minimum K/S oligomer effect on the K/S value of 6201 polyurethane acrylate 6104-806318, with the increase of oligomer content, the K/S value of the fabric first increased and then decreased, the amount of oligomer 30%, the maximum K/S value. With the increase of paste dosage, K/S value increases, when the amount of paste is more than 9%, K/S value is not increased, but declined. The wet rubbing fastness of dry rubbing fastness of the dyed fabrics, with the increase of functional monomers The dry and wet rubbing fastness of the oligomers 6104-80 and 6318 is the best, reaching 5 level. Compared with the original fabrics, the breaking strength of the UV curing coatings is basically increased and the elongation at break has decreased.
