Embodiment 1
[0044] The invention obtains the paper base of the ultra-thin seamed paper belt through the papermaking equipment. Such as figure 1 As shown, the papermaking equipment includes an unwinding device 1, an impregnation device 2, a drying device 3 and a winding device 4; the unwinding device 1, the impregnation device 2, the drying device 3 and the winding device 4 are connected in sequence. The impregnation device 2 includes a quantitative extrusion roller A for attaching the impregnation liquid to the base paper and a liquid filling device C for loading the impregnation liquid B. The quantitative extrusion roller A is suspended above the liquid filling device C, and the quantitative extrusion Roller A is in contact with impregnating liquid B. The drying unit contains several drying rollers.
[0045] In the papermaking equipment used in the present invention, the number of quantitative extrusion rollers A is 2. Quantitative extrusion roller A is composed of a bearing and a rub...

Abstract
The invention discloses a paper base of an ultra-thin type seaming paper tape as well as a preparation method and application of the paper base. By soaking raw paper through using steeping liquid, the average steeping moisture content is 100+ / -2g / m<2>, and the steeping dryness content is 22+ / -0.5g / m<2>; the solid content of the steeping liquid is 22+ / -0.5 percent, and a solid substance is the mixture of carboxyl butylbenzene emulsion and acrylic ester emulsion which are obtained by the mixture ratio according to the mass ratio of (2.5-3):1; and then, paper after being soaked, which is obtained by preparation, is dried at 130 to 155 DEG C and is soaked again for eliminating static electricity so as to obtain the paper base of the ultra-thin type seaming paper tape. The thickness of the paper base of the ultra-thin type seaming paper tape is only 45 to 50 percent of that of a common product; and however, the tensile strength (humidity) of the paper base of the ultra-thin type seaming paper tape reaches 180 percent of that of the common product, and the water resistance of the paper base of the ultra-thin type seaming paper tape is 3 to 8 times that of the common product. The material of the paper base of the ultra-thin type seaming paper tape has good bonding property with a jointing material, and the paper base of the ultra-thin type seaming paper tape is not easy to crack after construction. Moreover, because the thickness of the paper base disclosed by the invention is thin, the paper base is suitable for thin-layer rendering. The product provided by the invention has good water resistance and is suitable for a construction environment with high humidity.
Description
technical field [0001] The invention relates to a paper base, in particular to a paper base of an ultra-thin joint paper tape, a preparation method and application thereof. Background technique [0002] Seam paper is used for the seam treatment of plane seams, inner corners and outer corners to enhance the strength of the seams and solve the problem of seam cracking. Seam paper is different from ordinary paper. Due to its purpose of use, it is required not only to have high tensile strength, but also to maintain good physical properties (such as tensile properties, waterproof properties, and bonding properties, etc.). The plane being seamed looks smoother, and the thickness of the seaming paper should be as thin as possible. [0003] At present, the seam paper widely used in the market still has the following deficiencies: ① thick, not suitable for thin-layer plastering; ② low strength, poor adhesion to the coating, and easy to crack after construction; ③ poor water resista...
