Abstract

The invention relates to a composite sealer for color paintings of ancient buildings. The composite sealer is prepared from 19-21 portions of ZB-F600 dual FEVE waterborne fluorocarbon resin of 5% mass concentration, 0.5-1.5 portions of painting curing agent, 0.1-0.5 portion of B-63 water-soluble epoxy resin and 1-2 portions of nanometer silicon dioxide dispersion. After being tested by aging, surface water-refusing and water-resistance property, adhesion force, toughness, hardness and color difference tests, the invention has the advantages of good weather fastness, water-resisting property, strong adhesion force, good toughness, pollution resistance property, wear-resisting property, and the like. After the sample is treated by the composite sealer, the color is not obviously changed. The invention can be used for treating the problems of flaking, powdering, cracking, wrapping, casting, and the like of the color paintings of ancient buildings, and can be also used for protecting new color paintings.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a preparation for chalking, peeling, cracking, warping and shedding of ancient building colored paintings. Background technique [0002] Ancient architectural color painting is an important part of Chinese ancient architecture and a unique architectural decorative art in my country. It not only has the function of protecting wooden components of buildings, but also has the effect of decoration and beautification. As early as the Spring and Autumn Period, there were records of applying red paint on wooden structures; during the Southern and Northern Dynasties, due to the influence of Buddhist art, new architectural decorative patterns were produced; Deep or from deep to shallow, the change is soft without rigidity, showing an elegant style. These can be confirmed in "Zao Fa Shi" written by Li Zhongming in the Song Dynasty. In the Ming and Qing Dynasties, color pain...
