Abstract
The invention relates to vacuum type thermal transfer printing body paper and a method for preparing the same. The vacuum type thermal transfer printing body paper is used for printing processing carrier materials of aluminum section bars. The method includes preparing raw materials including 20-5-wt% of softwood pulp, 48-70wt% of hardwood pulp and 0.1-20wt% of talc; performing repulping for the prepared raw materials for 3 to 10 minutes; performing defibrination for the pulp mixture, then feeding the pulp mixture into a machine chest in a beating manner, and then feeding the pulp mixture into a proportioning pond in a beating manner while adding auxiliaries into the proportioning pool to realize proportioning; feeding the proportioned pulp into a pulp regulating pond to be regulated in a beating manner, and sequentially enabling the pulp to enter a papermaking forebay, a paper machine high-level box, a paper machine mesh and a paper machine squeezing portion to obtain a primary printing body paper product; adding auxiliaries into the paper machine high-level box; setting the vacuum degree of the paper machine mesh to range from 0.05MPa to 2.0MPa and the vacuum degree of the paper machine squeezing portion to range from 2.0MPa to 4.0MPa; and drying to obtain a finished product. The vacuum type thermal transfer printing body paper is degradable and is low in cost, fine in body paper performance and convenient to use.
Description
technical field [0001] The invention relates to the scope of special paper in the papermaking industry, in particular to a preparation method of vacuum-type thermal transfer printing base paper and its products, which are used as processing carrier building decoration materials for printing aluminum alloy profiles. Background technique [0002] Transfer printing paper is a kind of technical paper that can transfer the color pattern printed on the paper to cloth, porcelain, wood, glass, marble, etc. through heat treatment. [0003] CN101418525B (2010-11-03) discloses a transfer printing paper for one-time printing of sublimation patterns and bright color patterns and a preparation method of the transfer printing paper, in which bright patterns are printed on fabrics through a heat sublimation transfer printing process. [0004] It is made of transfer base paper coated with transfer solution (ink, dye, paint, adhesive, etc.). The transfer base paper is required to have high t...
