Abstract

The invention provides a two-component coating type antiskid coating material and a preparation method thereof. The antiskid coating material is composed of a component A solution and a component B solution, wherein the component A solution is composed of the following components by weight: 30-50% of waterborne polyurethane modified epoxy resin, 10-15% of a nano Al2O3 and CaCO3 dispersion liquid, 25-30% of fluff powder, and the balance of water, and the component B solution comprises the following components in percentage by weight: 30-50% of a polyamide curing agent, 1-2% of a defoaming agent, 1-2% of a flatting agent and the balance of water. According to the invention, the two-component anti-skid coating material is coated on the paper slide plate, so that the surface friction coefficient is increased, the anti-skid capability of the paper slide plate is enhanced, and the problems that the paper slide plate is easy to slip in the stacking and carrying processes, cannot be carried and loaded on equipment and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of anti-skid paper preparation, in particular to a two-component coating type anti-skid coating and a preparation method. Background technique [0002] Paper skateboards can be used as pads or pallets in different occasions and environments, and have broad development space and application prospects in the field of transportation packaging. It is light in weight, cheap, high in strength, recyclable, and its thickness is only about 1mm. It saves transportation and storage space to a great extent, thereby reducing freight and storage costs. It is used to replace wooden pallets, plastic pallets, and paper pallets for transportation. A new type of environmentally friendly packaging material for appliances. [0003] The paper slide board is made of multi-layer high-strength kraft cardboard through the board-making equipment, but the paper is easy to become smooth so that it will slip during the accumulation and ...
