Description
Technical field
The present invention relates to a kind of hanging raw stock, PVC wallpaper body paper being specifically related to a kind of acid/alkali-corrosion-resistant and preparation method thereof.
Background technology
What wallpaper became many owners gradually as a kind of wall surfacing material is first-selected, the advantages such as its color is various, pattern abundant, environmental protection attractive in appearance, there is the advantage that many traditional wall coverings are incomparable, improve year by year in the utilization rate of China, PVC wallpaper is the common wallpaper of a class, it is mainly with pure paper as base material, and then at substrate surface coating polyvinyl chloride resin sizing material, then postmenstruation, ornamenting processing process obtained finished product.
Body paper directly has influence on operation effect and the service property (quality) in wallpaper later stage as base material, current body paper material ubiquity intensity, poor toughness, surface absorption are uneven, glue not easily applies, water resistant poor heat resistance, grow bacterium and the shortcoming such as to mildew, have a strong impact on the serviceability of finished product, therefore the composition and engineering improving traditional body paper is had very much, improve its adaptability, improve post-production performance, to realize High-efficient Production, obtain quality product.
Summary of the invention
The object of the invention is PVC wallpaper body paper providing a kind of acid/alkali-corrosion-resistant and preparation method thereof, and to achieve these goals, the technical solution used in the present invention is as follows:
PVC wallpaper body paper of a kind of acid/alkali-corrosion-resistant and preparation method thereof, it is characterized in that, this body paper is made up of the raw material of following weight portion: bamboo pulp 20-30, bleaching esparto pulp 18-25, softwood pulp 35-42, eucalyptus leaves plant extraction liquid 1-2, methenamine 1-3, sodium alginate 3-5, fluorophologopite powder 4-6, barium sulfate 5-8, PAE wet strength agent 4-5, water-based defoamer 1-2, Imidazole cation lubricant 1-2, ethoxylated alkyl sulfate 0.5-1,800-1250 order environmental-friendly pigment 12-18, adhesive 12-15, auxiliary agent 3-5;
Auxiliary agent is made up of the raw material of following weight portion: polymine 4-6, neopelex 0.2-0.5, poly-l-lysine (molecular weight 70000-150000) 2-3, sweet mellow wine 1-1.5, oxidized starch 6-8, water-based defoamer 0.1-0.2, atoleine 1-2, water 12-16, preparation method is: first by polymine, neopelex, atoleine drops in 50-60 DEG C of hot water, fully be uniformly mixed and make material dissolve dispersion completely, add sweet mellow wine more subsequently, oxidized starch, be uniformly mixed 30-40min, finally add other leftover materials again, continue insulated and stirred mixing 40-50min, by the rapid draing of gained material after stirring terminates, removing moisture, and be ground into fine powder and get final product.
Described adhesive is aqueous non-toxic adhesive.
PVC wallpaper body paper of described a kind of acid/alkali-corrosion-resistant and preparation method thereof, its preparation method is:
(1) first bamboo pulp, bleaching esparto pulp, softwood pulp mixing are dropped into thin up making beating in beater, beating degree is 28-35
0sR;
(2) by fluorophologopite powder, barium sulfate and Imidazole cation mix lubricant grinding distribution 40-50min, 600-800 mesh sieve is crossed;
(3) step (1), step (2) gained material are mixed with other residual components except pigment, adhesive, auxiliary agent, after being uniformly mixed 1-2h, mixed slurry manufactured paper with pulp through long mesh paper making machine, dry, obtain semi-finished product body paper;
(4) adhesive input is doubled in the water of its weight portion, auxiliary agent, pigment is added after dilution evenly, high-speed stirred makes it mix completely, obtain surface coating liquid, subsequently this surface coating liquid is coated the semi-finished product body paper surface of step (3) gained, then drying, surface pressure polishing decorations, batch after namely obtain body paper and become paper.
Body paper advantage of the present invention is: by softwood pulp, bamboo pulp, straw pulp mixing making beating, the paper of preparation has good gas permeability and toughness, eucalyptus leaves plant extraction liquid in raw material is combined with methenamine can generate photoresistive substance, again with the fluorophologopite powder after surface treatment, the fillers such as barium sulfate together, impart the acid-alkali-corrosive-resisting ability that semi-finished product body paper is excellent, and paper strength obtains lifting, surface is compacted smooth, and auxiliary agent, it is full that pigment and adhesive dilute the surface coating liquid uniform color prepared, keep effective, easy coating, can effectively promote body paper intensity, strengthen water resistant ability, make body paper smooth surface fine and close, postorder process is more efficient.To sum up, hanging raw stock environment-protecting asepsis of the present invention, water-fast corrosion-resistant, good physical properties, is easy to post-production, lays a good foundation for producing high-quality wallpaper finished product.
