Problems solved by technology

[0003] However, most of the stone paper currently produced is made of polypropylene and calcium carbonate as the main materials. This kind of stone paper generally has problems such as poor printing adaptability, poor stiffness, poor shading, and low strength, which lead to the failure of finished products. Oil-based ink is generally used for printing, the color is single, the smell is strong, and it is difficult to solve the environmental protection problem of the ink. The above problems are also the bottleneck problems that are difficult to promote the large-scale application of stone paper.

Abstract

The invention discloses a stone paper masterbatch composition, a production method of masterbatch and an application thereof. The composition is prepared from the following components in parts by weight: 20-90 parts of polypropylene, 10-80 parts of inorganic water absorbing filler, 1-2 parts of an interface activator SBW-111, 1-2 parts of a printing aid B-903 and 0.1 part of an antioxidant. The invention also discloses the application of the prepared masterbatch. The preparation method is simple in process, easy to operate, mild in raw material mixing condition and high in production efficiency. Stone paper prepared by the product has the advantages of being low in production cost, good in product quality and recyclable, is particularly suitable for polychrome color printing of waterborneink, is good in printing quality, improves the grade of the product, and can be applied to the field of packaging.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a stone paper masterbatch composition, a production method of the masterbatch and an application thereof. Background technique [0002] At present, stone paper is an environmentally friendly product made of inorganic minerals as the main raw material, which is modified by physical and chemical methods and compounded with polymers. It has the characteristics of low price and simple production process. Compared with traditional papermaking, stone paper uses natural minerals as raw materials, does not need to cut down wood, protects a large number of vegetation resources, and indirectly enhances the purification ability of the atmosphere. At the same time, compared with the traditional paper industry, the production process of stone paper does not require cooking and separating fibers, washing, bleaching and other processes, so it does not need to use chemical raw ma...
