Problems solved by technology

[0005] (2) Oil paintings are prone to aging during preservation, and their outdoor weather resistance is poor. It is inevitable that they will turn yellow and darken. The operation of removing the old varnish layer is very cumbersome and requires the use of solvents such as turpentine, gasoline, benzene, alcohol, etc. These solvents are also harmful to the human body and the environment;
[0006] (3) It is only suitable for painting on various types of canvas, linen, cardboard or wood substrates. The scope of application is limited and it cannot meet the needs of painting on other substrates.

Abstract

The invention discloses an organosilicon pigment. The organosilicon pigment is prepared from a component A and a component B, wherein the component A is prepared from the following components in partsby weight: 50 to 100 parts of organopolysiloxane, 1 to 10 parts of filler, 20 to 80 parts of toner and 0.5 to 5 parts of organic hydride polysiloxane, 0 to 10 parts of silicon resin, 0.5 to 5 parts of a tackifier and 0 to 0.2 part of a reaction inhibitor; the component B is prepared from the following components in parts by weight: 50 to 100 parts of the organopolysiloxane and 0.1 to 2 parts of areaction catalyst. The invention also provides a preparation method and a use method of the organosilicon pigment. The pigment disclosed by the invention has the advantages of good oxygen and aging resistance, good light and aging resistance, good mildew resistance and chemical stability; in addition, the organosilicon pigment can be stored stably for a long time, and the problems of color change, aging and cracking of the materials and the like are solved, so that long-term preservation and no maintenance of oil paintings can be really realized.

Description

Technical field [0001] The invention belongs to the field of oil painting production, and in particular relates to an organic silicon pigment and a preparation method and a use method thereof. Background technique [0002] Oil painting is a kind of painting made with quick-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.) on canvas, linen, cardboard or wood. When the picture is dry, the surface of the oil painting has a strong Hardness, relying on the hiding power and transparency of oil paintings to fully express the painted objects, rich colors, strong three-dimensional texture, is the main painting method in the history of Western painting. At present, the raw materials used for painting include volatile turpentine oil and dry linseed oil. In order to maintain the gloss of the picture and prevent the aging phenomenon caused by air erosion and dirt accumulation, varnish is usually applied after the oil painting is completed and dried. [0003] However, the raw mate...
