Abstract
The invention discloses a method for manufacturing high-breathability non-woven wallpaper body paper and a product. The existing non-woven wallpaper has the disadvantages that the hand feel thereof is not soft enough, the principal plane stereoscopic impression is not strong and the opacity degree is low. The method of the invention comprises the following steps: beating plant fiber containing chemical wood pulp until the beating degree is 20-30OSR, and mixing with non-plant fiber containing chemical fiber; adding chemical addition agent into the mixed fiber; manufacturing the mixed fiber containing the chemical addition agent into body paper semi-finished products by utilizing a fourdrinier wire or inclined wire paper machine; mixing pigment, chemical addition agent and adhesive to form coating liquor, carrying out dip coating on the body paper semi-finished products inside or outside the machine; and drying and finishing the body paper subject to dip coating, and rolling the body paper to form finished paper of body paper, thus obtaining non-woven wallpaper which contains continuous fiber, has high breathability, and can be directly printed. The principal plane has natural lines; and the finished paper has the advantages of soft hand feel, good processability, excellent shape stability, rich color, distinct image and strong stereoscopic impression.
Description
Technical field
The present invention relates to a kind of novel nonwoven wallpaper, especially relate to the nonwoven wallpaper that contains long fiber, highly-breathable, can directly print.
Background technology
Wallpaper (Wallcoverings or Wallpaper) is a kind of widely used indoor wall ornament materials, and with rich color, skin texture texture is strong, rich patterns, and the decorative effect noble quality is elegant and superior, purposes is more and more wider.
Traditional wallpaper is to be base material with the hanging raw stock, through various forms of coatings or calendering, printing, cotton ginning, or foaming and a kind of body of wall art work of processing.This type wallpaper is owing to be basic material with the wood pulp fibre body paper mainly; Therefore processing or use exist intensity relatively poor, easily with environmental condition the deform shortcoming such as indifferent of contraction, water-fast and anti-cleaning of the variation of humidity particularly; And the whole manufacturing process link is more, and energy consumption is bigger.
The nonwoven wallpaper is the novel wall surface ornament materials that grew up in recent years; Have rich color, clear patterns, the decorative effect noble quality etc. except that the same with traditional wallpaper; Therefore advantages such as also having the paper strength height, be not easy distortion, soft, paper shows the fiber natural grain especially, third dimension is strong, can directly print more and more receives the welcome in market.
At present the nonwoven wallpaper is mainly by specialized factory's production of American-European countries such as Germany, the U.S., Italy, the research and development of China's nonwoven wallpaper and produce at the early-stage.200810063378.0 number Chinese invention patent application and No. 200810060243.9 Chinese invention patent applications disclose the preparation method of long fibre nonwoven hanging raw stock and nonwoven wallpaper thereof respectively; Mainly be to disclose used kinds of fibers, proportioning and adhesive etc.; Particularly adopt dip-coating and the outer method that combines that is coated with of machine in the machine; Its shortcoming is the nonwoven wallpaper processed because adopt common long mesh paper making machine or oblique net paper machine to manufacture paper with pulp to add behind the body paper the outer coating of machine to cause that tightness is high, closure is big, feel is soft inadequately, air permeability is low again; The shortcoming of the outer coating of machine is that the natural grain of paper can not get guaranteeing because the covering of coating makes, third dimension is not strong in addition; And the pigment that adopts hides poor-performing, the higher nonwoven wallpaper that causes of coating weight becomes paper opacity lower (all being lower than 90%), with up-to-date nonwoven wallpaper technological gap is bigger in the world.

3, tensile strength 4.5kn/m, wet strength 2.0kn/m, surface absorption 50g/m
2(60s), air permeability (0.74kPa) 2200ml/min, opacity 94%, lateral extensometer shrinkage 0.25%.
This embodiment, through calculating, body paper becomes the mass percent of string in the paper, non-plant fibre, pigment, adhesive, other chemical addition agents to be respectively 28.88,53.63,11.99,4.20,1.3.
Characteristics such as the nonwoven hanging raw stock that above embodiment obtains becomes paper product to have highly-breathable, intensity is high, and printing performance is good and paper fiber natural grain are true to nature, and third dimension is strong, can directly print, and is wallpaper family high-end product.
Above embodiment realizes nonwoven hanging raw stock of the present invention through selecting concrete string, non-plant fibre, pigment, adhesive, chemical addition agent for use; Through practice; From raw material disclosed by the invention, select string, non-plant fibre, pigment, adhesive, chemical addition agent for use and replace oblique net paper machine and realize manufacturing paper with pulp, can realize the present invention equally, give unnecessary details no longer one by one with dip coated in the alternative machine of dip coated outside the machine with long mesh paper making machine.And, nonwoven hanging raw stock of the present invention is processed (like calendering, printing, cotton ginning or foaming etc.) can get and can be attached to the highly-breathable nonwoven wallpaper that the enterprising luggage of wall is repaiied decoration.
