A wide-width oil-resistant canvas and its preparation method

Abstract

The invention discloses a wide-range flame-retarding canvas. The wide-range flame-retarding canvas includes a fire retardant fabric base material; a layer of flame-retarding primer is coated on the fire retardant fabric base material, and the flame-retarding coating is coated on the flame-retarding primer; the formula and dosage of the flame-retarding primer according to part by weight are: 20-40 parts of ammonium polyphosphate APP, 5-15 parts of melamine MEL, 10-20 parts of dipentaerythritol DPER, 0.5-2 parts of wetting agent, 0.5-2 parts of antifoaming agent, 10-30 parts of pure acrylic emulsion, 40-50 parts of ethylene-vinyl acetate copolymer emulsion, 20-30 parts of 70% of titanium dioxide powder syrup, 0.5-2 parts of brightening agent, 100-110 parts of water, and 5-8 parts of thickening agent. The wide-range flame-retarding canvas can be printed by compatible solvent type, weak solvent type and UV solidifying type inks, and has excellent smoothness and fineness, coating firmness, good weather resistance, moisture-resisting humidity and exquisite grain line and inkjet resolution rate. Meanwhile, the wide-range flame-retarding canvas can satisfy the foreign canvas flame-retarding standard and reach the highest flame-retarding standard B1 grade at home.

Description

technical field [0001] The invention relates to an oil painting cloth and a manufacturing method thereof, in particular to a wide-width oil-resistant oil painting cloth and a preparation method thereof. Background technique [0002] The art of oil painting originated from the West and has not yet been popularized in our country. In the past, the production and application of oil canvas in my country was almost blank. With the deepening of my country's reform and opening up, people's living standards have improved significantly.

Problems solved by technology

In order to meet the needs of the European and American markets, a batch of oil canvases with so-called flame-retardant effects began to appear on the market. There are generally the following problems: (1) The flame-retardant performance is not up to standard; (2) The base glue caused by adding too much inorganic flame-retardant powder Poor bonding fastness to cloth base, primer oil absorption, oil leakage, oil penetration, coating peeling, powder falling, coating printing resolution is not up to standard; (3) Oil canvas weather resistance, moisture resistance and other problems
