Abstract

The invention provides a markrolon/modified polyester blending rolling base material and a preparation method thereof. The markrolon/modified polyester blending rolling base material comprises the following components by weight percent: 55-65% of makrolon, 15-20% of modified polyester, 4-8% of modified copolyesters additive, 3-5% of compatilizer 4051, 4-7% of titanium white, 2-6% of calcium carbonate and 0.01-0.1% of pigment. The vicat softening point of the invention can be 115 DEG C+/-2 (50-5kg of vicat A), the tensile strength is larger than 45Mpa, the tensile yield strength is larger than 750KJ/m<2>; and the invention meets the rolling technology requirement by improving the formula lubrication systems, can meet the requirement of the processes such as material application, card making technology of smart card base materials and the like.

Description

technical field [0001] The invention relates to a calendered base material with polycarbonate / modified copolyester as the main material. Background technique [0002] ID cards, transportation cards, etc. are important documents that are indispensable in people's daily life. The card base materials for the above-mentioned documents are usually made of polyvinyl chloride or polyvinyl chloride blend materials, although they have high flame retardancy, etc. Advantages, but it also has the disadvantages of low heat-resistant softening point, low impact resistance, easy to produce toxic substances after decomposition, serious environmental pollution, non-wear resistance, poor processing performance, etc., which cannot meet the high heat resistance and high impact resistance of materials in the high-end market. , high wear resistance and environmental performance requirements. Contents of the invention [0003] The technical problem to be solved in the present invention is to di...
