Flat filament master batch and preparation method thereof

Abstract

The invention relates to the technical field of plastic processing, and concretely relates to a flat filament master batch and a preparation method thereof. The flat master batch comprises, by weight,8-15 parts of carrier resin, 5-10 parts of a toughening modifier, 0.8-1.2 parts of a dispersant, 1-3 parts of a coupling agent and 76-82 parts of inorganic rigid particles. The inorganic rigid particles are activated under the action of the dispersant and the coupling agent with the carrier resin as a matrix in order to make the inorganic rigid particles well dispersed in the carrier resin, the toughening modifier has good compatibility with the carrier resin and the activated inorganic rigid particles in order to increase the toughness of the flat filament master batch, and the interaction of the carrier resin, the activated inorganic rigid particles and the toughening modifier improves the impact strength, the durability and the puncture resistance of the flat filament master batch, increases the draw ratio, improves the unit tensile force and prevents the reduction of the tensile strength and elongation of the flat filament master batch after the addition of the inorganic rigid particles, so the flat filament master batch is durable, and the effects of consumption reduction and cost saving are achieved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a flat wire masterbatch and a preparation method thereof. Background technique [0002] Plastic woven bags are a kind of plastic packaging commonly used in production and life. With the improvement of living standards and the increasingly fierce market competition, people have higher and higher requirements for plastic woven bags, requiring products to have higher tension and more Low price, which requires better reduction of energy consumption and production cost in the production process. Using filler masterbatch to reduce production cost is a common method in the production of plastic woven bags. Although adding ordinary filler masterbatch will reduce production Cost, but will greatly reduce the tensile strength of the woven bag. Therefore, there is an urgent need for a flat wire masterbatch that can reduce production costs while maintaining tensile strength, which...
