【摘要】：目前天然纖維復合材料逐步引起了學術界和工業(yè)界的廣泛關注,這是由于其本身的一些潛在特質,尤其是在環(huán)保方面。真絲纖維作為天然纖維的一種,制備的復合材料除了具有環(huán)�？山到獾忍攸c,還具有輕質和高應力應變性。同時真絲纖維表面含有-NH2,-COOH,-NHCO-,-CH2OH等極性基團,這使真絲纖維和聚合物基體結合形成良好的力學界面。國外通常以廢棄真絲纖維制備的復合材料用于做生物材料、工程材料以及一些專屬的輕質結構件,很少用于裝飾材料。本文探討的真絲織物/PE膜復合材料由層壓法制備,主要用于裝飾,具有易清潔、耐油污、強力高及綠色環(huán)保等優(yōu)點。整個制備過程在真空條件下進行,擯棄了傳統(tǒng)層壓法易產生氣泡、分層嚴重的現(xiàn)象,相比模壓法制備簡單快速,大大提高了生產效率。本文主要分析了真絲織物與PE膜復合材料的制備工藝與其性能之間關系。首先以真絲織物復合前后色差變化△E值為測試指標,將熱壓溫度、熱壓壓力、熱壓時間及復合材料的厚度4個因素進行正交試驗分析,通過分析可知,各個工藝因素對色差變化影響的主次順序為：復合材料的厚度熱壓溫度熱壓時間熱壓壓力,其中只有復合材料厚度為顯著性因素,采用一元線性回歸分析得出了復合材料厚度和色差值之間線性關系,回歸方程為：Y=1.506+7.690X,并優(yōu)化出復合材料最優(yōu)厚度選為0.3mm。在厚度一定的情況下,采用響應面法分析對復合材料的各個力學性能進行分析得出：制備復合材料拉伸強力的最優(yōu)工藝為：熱壓溫度145.6℃、熱壓壓力3.9 MPa和熱壓時間4.4 min,各工藝因素對拉伸強力影響的順序為熱壓壓力熱壓時間熱壓溫度,‘熱壓溫度、熱壓壓力和熱壓時間之間幾乎沒有的交互作用；制備復合材料撕裂強力的最優(yōu)工藝為：熱壓溫度146.4℃、熱壓壓力3.4 MPa和熱壓時間4.7 min,各工藝因素對撕裂強力影響的順序為熱壓溫度熱壓時間熱壓壓力,熱壓溫度、熱壓壓力和熱壓時間之間有一定的交互作用,但作用不很明顯；制備復合材料頂破強力最優(yōu)工藝為：熱壓溫度147.5℃、熱壓壓力4.1MPa和熱壓時間5.7 min,各工藝因素對頂破強力影響的順序為熱壓壓力熱壓溫度熱壓時間,熱壓溫度、熱壓壓力和熱壓時間之間有明顯的交互作用。最后,根據(jù)各個因素的對復合材料力學性能的顯著性不同,對復合材料的力學性能進行綜合性分析,得出制備復合材料的最優(yōu)工藝條件：熱壓溫度為146.4℃,熱壓壓力為3.9MPa,熱壓時間為4.7 min。本文對真絲織物的綜合利用及裝飾用復合材料制作提供一定參考作用。
[Abstract]:At present, natural fiber composites have attracted more and more attention in academia and industry, which is due to its own potential characteristics, especially in the field of environmental protection.Silk fiber is a kind of natural fiber. The composite material not only has the characteristics of environmental protection and degradability, but also has the characteristics of light weight and high stress denaturation.At the same time, the surface of silk fiber contains polar groups such as -NH _ 2H _ 2-COOH _ (-COOH) -NH _ CO _ (-C) -CH _ 2O _ H, which makes the silk fiber and polymer matrix combine to form a good mechanical interface.Abroad, composite materials made of waste silk fibers are used as biomaterials, engineering materials and some special lightweight structures, but rarely used as decorative materials.The silk fabric / PE film composite prepared by lamination is mainly used for decoration. It has the advantages of easy cleaning, oil resistance, high strength and green environmental protection.The whole preparation process was carried out in vacuum condition, which abandoned the phenomenon that the traditional lamination method was easy to produce bubbles and the stratification was serious. Compared with the molding method, the preparation process was simpler and faster, and the production efficiency was greatly improved.In this paper, the relationship between the preparation process and properties of real silk fabric and PE film composites is analyzed.In this paper, the color difference of silk fabric before and after recombination is taken as the test index. The factors of hot pressing temperature, hot pressing pressure, hot pressing time and the thickness of composite material are analyzed by orthogonal test.The main and secondary order of the influence of each technological factor on the color difference is as follows: the thickness of the composite material is hot pressed, the temperature and the time of the hot pressing pressure, among which the thickness of the composite material is the significant factor.The linear relationship between the thickness of composite material and the value of color difference was obtained by linear regression analysis. The regression equation was: 1. 506 7.690X. and the optimum thickness of composite material was chosen as 0.3mm.Under the condition of constant thickness, the mechanical properties of the composites were analyzed by response surface method. The results showed that the optimum process for preparing the tensile strength of the composites was as follows: the hot pressing temperature was 145.6 鈩，
