The invention provides a fast oil-absorbing oil canvas. The specific steps are: (1) dissolving the glue with deionized water; wherein, the glue is transparent acrylic glue or animal glue; (2) adding titanium dioxide, polymethacrylic acid ten Hexaester, polycarboxylic acid and its salt, ammonium bicarbonate, mixed evenly; among them, the mass ratio of titanium dioxide, polyhexadecyl methacrylate, polycarboxylic acid and its salt to water is 0‑0.1:0.5‑0.7 :0.2‑0.3: 1, (3) Brush the glue mixed solution evenly on the linen cloth, after drying, brush the next layer, the glue layer is 6‑10mm, and finally brush a layer of glycerin; (4) Dry at high temperature. The processing method is simple and convenient, with good oil absorption and no oil bleeding. After multiple times of painting, apply another layer of glycerin to ensure that the oil will not bleed in the later stage.

The invention discloses synthetic latex diatom inner wall emulsion paint and a preparation method thereof. The inner wall emulsion paint is prepared from, by weight, 260-300 parts of polymer emulsion, 1-5 parts of hydroxyethyl cellulose, 200-220 parts of diatomite, 10-25 parts of anti-freezing agents, 15-17 parts of film-forming auxiliaries, 1-5 parts of thickeners, 1-5 parts of flatting agents, 4-8 parts of wetting dispersants, 1-5 parts of defoaming agents, 60-120 parts of filler and 300-315 parts of water. The PVC / CPVC of the emulsion paint is 1.1-1.3. The PVC is the pigment size concentration of the emulsion paint, and the CPVC is the critical pigment volume concentration of the emulsion paint. The inner wall emulsion paint has water resistance, washability and air permeability at the same time, and the diatomite can effectively release anions.

The invention discloses a preparation method of low-temperature curing type waterborne amino acrylic resin. The preparation method comprises the following steps of performing esterification reaction on melamine formaldehyde resin and acrylic acid to obtain an amino acrylic ester macromonomer; mixing the amino acrylic ester macromonomer into an acrylic monomer emulsion, and polymerizing to obtain a polyamino acrylic ester emulsion; mixing the polyamino acrylic ester emulsion and water-soluble blocked isocyanate, so as to prepare the low-temperature curing type waterborne amino acrylic resin. The preparation method has the advantages that the melamine formaldehyde resin is mixed into the acrylic acid to prepare the amino acrylic ester, and multiple types of acrylic ester are mixed into the amino acrylic ester, so that the properties of the emulsion and a rubber film are improved, the anti-scratching and anti-corrosive properties of a coating film are improved, and the service life of the coating film is prolonged; after the isocyanate which is blocked by sodium bisulfite is used, the self disadvantages are overcome by the advantages of the isocyanate and the acrylic ester, and the coating film has the water-proof, anti-aging and anti-corrosive properties of the amino acrylic ester, and also has the property of low curing temperature of the isocyanate.

The invention discloses a pressurization alkali-boiling method for removing a ceramic layer in a thermal barrier coating. According to the pressurization alkali-boiling method for removing the ceramiclayer in the thermal barrier coating, alkali liquor is used for removing the ceramic layer in the thermal barrier coating; when the ceramic layer is removed, an alpha-Al2O3 layer on the interface ofthe ceramic layer and a metal layer chemically reacts with an alkali solution under a high temperature and a high pressure, so that the ceramic layer is tripped, damage to the metal bottom layer is avoided, and the metal bottom layer does not need to be repaired, so that the procedures are simple, and re-coating of the ceramic layer is facilitated. The pressurization alkali-boiling method can be implemented conveniently and rapidly, the equipment structure is simple, and operation is easy. Compared with a traditional mechanical sand blasting method, the process parameters can be accurately controlled, and the consistency of the product quality is high. It is found through practice that a ceramic layer of a part treated through the method is completely removed and effectively stripped without damaging a metal layer; and the thickness of the metal bottom layer is not changed before and after the ceramic layer is removed.
