Description
Technical field
The present invention relates to a kind of nonwoven wallpaper, especially relate to a kind of long fibre nonwoven wallpaper base stock and preparation method thereof and nonwoven wallpaper prepared therefrom.
Background technology
Nonwoven wallpaper is a kind of novel decorative material for wall surface.It has rich color, the myoplasm sense is strong, pattern is gorgeous, environmental protection, easy construction, price suitable, and characteristics such as the noble elegance of decorative effect are that other multiple indoor ornament materials is incomparable.But wallpaper in the past all is basic material with the wood pulp fibre, this wallpaper low price, shortcoming be poor performance, not water-fast, be not easy to clean, be not easy to construction, because wood pulp fibre can absorb airborne moisture content in a large number, the surface can have damp, time to grow often can existing stain.When changing wallpaper, owing to himself intensity difference, cause and peel off not exclusively, sticking wall phenomenon appears.Aspect fire prevention,, can not prevent fires in addition, so this wallpaper is difficult for promoting because wood pulp fibre belongs to inflammable thing.
The main raw material(s) of wallpaper is exactly a wallpaper base stock, and wallpaper base stock is a kind of basic material.The finished product wallpaper is exactly that the coating by variety of way, printing, embossing etc. process pattern on its surface, and its main performance is determined by body paper.Whole wood pulp body paper in the past causes the pattern displacement unintelligible adding the phenomenon that contraction appears in man-hour easily.Because of it is done, wet strength is poor, the difficulty of construction is also big simultaneously.
For this reason, the applicant has applied for that application number is: 200810060243.9 applyings date: the patent of invention on March 31st, 2008, nonwoven wallpaper base stock is disclosed, it comprises fibre stuff and adhesive, fibre stuff comprises wood pulp fibre and functional fibre, wood pulp fibre and functional fibre are 0～95%: 5～100% by part by weight between the two, and adhesive accounts for 1～10% of body paper gross weight.
In actual production, if the applicant finds the length of functional fibre is extended, owing to have long fiber destroying long fibre nonwoven wallpaper base stock surface made of paper, then long fibre nonwoven wallpaper base stock is after coating, the surface of wallpaper can show the striped of nature, good looking appearance does not need to handle in addition.
Summary of the invention
The objective of the invention is in order to solve traditional wallpaper profile not attractive in appearance, defective in needing to handle in addition an object of the present invention is to provide the anti-water of a kind of energy, mildew-resistant, anti-wiping, easily peels off, the long fibre nonwoven wallpaper base stock of good looking appearance behind the good processability, coating.An other purpose of the present invention provides the preparation method of above-mentioned long fibre nonwoven wallpaper base stock, and it adopts copies the preparation of paper method.The 3rd purpose of the present invention provides the nonwoven wallpaper that is prepared by above-mentioned wallpaper base stock, and it has the striped of nature, good looking appearance.
In order to realize first above-mentioned purpose, the present invention has adopted following technical scheme:
Long fibre nonwoven wallpaper base stock, this body paper comprises fibre stuff and adhesive, fibre stuff comprises wood pulp fibre and functional fibre, and wood pulp fibre and functional fibre are 0～95%: 5～100% by part by weight between the two, and adhesive accounts for 1～10% of body paper gross weight; It is 0.8～25D that described functional fibre contains a kind of fineness at least, and length is the functional fibre of 15～60mm.
In order to make paper can not occur man-hour shrinking adding, the functional fibre that adds can be animal fiber, artificial fibre, synthetic fiber and inorfil, as everyone knows, functional fibre becomes the tightness of paper all lower because its smooth surface, in raw material, add functional fibre after, the tightness of paper reduces, elasticity increases, and makes paper in process, and the shrinkage phenomenon of paper disappears.The water absorbent surface performance of chemical fibre is far below wood pulp fibre, and wood pulp fibre generally can absorb and be equivalent to self 9 times water, and the regain of chemical fibre is all below 5.0%, is zero especially as the regain of fibers such as polyvinyl chloride fibre, polypropylene fibre.Under equal tightness, the paper that adds functional fibre has just had the raising of matter than the paper WATER RESISTANCE of whole wood pulp like this.When functional fibre has fire resistance, become paper also certain fire resistance being arranged with regard to corresponding, just can allow paper have fire resistance as addings such as polyvinyl chloride fibre, aramid fiber and carbon fiber back.
Simultaneously, the adding fineness is 0.8～25D, length is the functional fibre of 15～60mm, owing to have long fiber destroying long fibre nonwoven wallpaper base stock surface made of paper, then long fibre nonwoven wallpaper base stock is after coating, the surface of wallpaper can show the striped of nature, and good looking appearance does not need to handle in addition.As preferably, it is 0.8～25D that functional fibre contains a kind of fineness at least, and length is the functional fibre of 30～60mm.As preferred again, it is 0.8～25D that functional fibre contains a kind of fineness at least, and length is the functional fibre of 40～60mm.
The addition of functional fibre generally between 5-100%, is less than at 5% o'clock in the functional fibre addition, and the characteristics of functional fibre can not embody, the amount that different fibers adds is differentiated, some fiber is not hydrophilic fully, after addition is many, manufactures paper with pulp and will become difficult unusually; And the picture viscose is owing to itself get by wood pulps spray silk, and its regain is than cotton also height, even 100% use, it is also out of question to manufacture paper with pulp.
Simultaneously in order to guarantee that paper has certain air permeability, the beating degree of wood pulp fibre is lower, and most functional fibres are to improve the intensity of paper and tightness by making beating, in order to guarantee the intensity of paper, must strengthen, what the present invention adopted is coating method in the machine, can certainly adopt the mode of adding in the slurry to increase the intensity of paper.
As preferably, functional fibre is a hydrophilic fibre, and the content ratio of hydrophilic fibre and wood pulp fibre is 10～100%: 0～90%, and optimum hydrophilic fibre addition is between 20～60%.As preferably, described hydrophilic fibre is one or more in animal fiber and the artificial fibre.Hydrophilic fibre is one or more in collagenous fibres, keratin fiber, fibroin fiber, regenerated celulose fibre and the azlon.As preferred again, above-mentioned keratin fiber is a wool, regenerated celulose fibre is one or more in viscose, copper ammonia fibre, the acetic ester fiber, and azlon is one or more in casein fibre, Zein fibers, ground nut fiber, the soybean fiber.
