The process in the invention is simple and rational, the product quality is stable and the effect is good.

The invention discloses a styrene-acrylic microemulsion surface sizing agent with high solid content and core shell structure and a preparation method and an application thereof. The preparation method comprises the following steps: adopting a seed emulsion method to synthesize core emulsion, dropping core pre-emulsified monomer solution and redox initiator into core the emulsion, controlling the dropping time, filtering the product of reaction by using a 250 mesh or 300 mesh sieve, discharging, and obtaining the microemulsion with hard core and soft core shell structure, wherein the microemulsion has a grain diameter of 20-100nm and the solid content of 40-48 percent. The surface sizing agent has the base characteristics of styrene-acrylic emulsion, good stability, core shell structure, small grain diameter, high solid content, and better gluing effect and can endow paper with better water resisting property and improve the surface property of the paper.

The invention belongs to the technical field of papermaking, and particularly relates to a white manila board and a preparation method thereof. Three layers of forming nets and two passes of coating (curtain coating and knife coating) are adopted for the white manila board; moreover, a core layer and a bottom layer are manufactured by adopting recycled fiber pulp which is low-cost and is further more environment-friendly to replace wastepaper de-inked pulp; not only can a production process of the white manila board be greatly simplified and optimized, but also the consumption of chemicals and the power consumption can be greatly decreased, so that the qualified and low-basis-weight white manila board which more accords with market requirements can be produced with low cost.
