Abstract

The invention discloses an unsaturated polyester material with excellent covering power, black edge covering capacity and combination property. The unsaturated polyester material is prepared from components in parts by weight as follows: 35-45 parts of PE resin, 2-4 parts of a 20% CAB551-0.2 solution (CAB551-0.220: BAC80), 0.2-0.4 parts of a dispersant, 1-3 parts of a polishing aid, 2-5 parts of an active solvent, 45-55 parts of inorganic filler, 0.2-0.4 parts of fumed silica, 0.2-0.5 parts of a polyamide wax dispersion rheological aid, 0.5-1.5 parts of 40% active content rheological aid, 0.5-1 part of a thickening rheological agent, 0.1-0.3 parts of a defoaming agent and 0.2-0.5 parts of a leveling agent. The unsaturated polyester material with excellent covering power, black edge covering capacity and combination property has excellent covering power and black edge covering capacity for special-shaped parts, chamfered objects and molded carved plates and has the characteristics of good leveling performance, good fullness and good rubbing property and the like of the unsaturated polyester material.

Description

technical field [0001] The invention belongs to the field of unsaturated polyester materials, and in particular relates to an unsaturated polyester material with excellent hiding power, black edge hiding ability and comprehensive performance and a preparation method thereof. Background technique [0002] High-solid unsaturated polyester solid-color materials on the market generally have irregular-shaped parts, edge-beveled objects, and shaped carved panels with poor hiding power and poor ability to hide black edges. [0003] In view of the deficiencies of the existing technology, there is an urgent need to develop an unsaturated polyester material with excellent hiding power, black edge hiding ability and comprehensive performance in this field, so as to broaden the construction tolerance of the unsaturated polyester primer and achieve the purpose of reducing environmental pollution . Contents of the invention [0004] Aiming at the deficiencies of the prior art, the inve...
