Problems solved by technology

The copolymers and pigments used in this patent application technology require good transparency, and the cost of raw materials is relatively high; on the other hand, the presence of various toxic components such as formaldehyde and epoxy resin in the raw materials is not good for the health of operators

Embodiment 1

[0008] Embodiment 1 (referring to the proportioning figure of parts by weight in the table below):

[0009] 35 parts by weight (hereinafter referred to as parts) of butyl acetate, 25 parts of amyl acetate, 25 parts of calcium halophosphate fluorescent powder, 10 parts of sodium fluorosilicate, 10 parts of titanium dioxide, 30 parts of acrylic resin, and 10 parts of nitrocellulose agent, 2 parts of silane coupling agent, 1 part of cellulose acetate butyrate, 1 part of cellulose acetate propionate, and 1 part of cellulose acetate are mixed and poured into a ball mill (tank) for ball milling for 3-4 hours. The speed of the ball mill is about 105r / min, pay attention to adjust the density of the slurry to about 1.34g / cm 3 (Slightly higher in winter and slightly lower in summer), the viscosity is controlled at 14-18s. If the viscosity is high and the density is low, add a little butyl (pentyl) acetate; if the viscosity is high and the density is low, add a little fluorescent dry p...

Abstract

The invention is a method for producing a glass lamp shade coating, characterized in it is prepared of the following components in weight share: butyl acetate and / or amyl acetate as solvent 40-60 weight shares, halogen calcium phosphate fluorescent powder and sodium fluorosilicate as pigment and filling 25-45 weight shares, acrylic resin and / or cotton powder adhesive as adhesive 30-40 weight shares, and silane coupling agent and at least one of the cellulose acetate butyrate, cellulose acetate propionate, and acetyl cellulose as assistant 3-5 weight shares; mixing them and ball-milling in a ball mill, fully dissolving and blending uniformly, filtering with 200-300 mesh net, and barreling and serving. And the coating is special for inner surface of the glass lamp shade to generate milk-white soft light. As compared with the existing technique, it has advantages of fewer harmful components to human health and lower production cost.

Description

technical field [0001] The invention relates to a production method of a coating on the inner surface of a glass lampshade. Background technique [0002] CN02153634.1 discloses Mr. Li Chenggui's "Frosted Paint for Decorative Light Bulbs and Coating Method" patent application data, using 30-45% transparent melamine, sulfonamide, formaldehyde copolymer or its The main component of raw materials with the same properties (barium sulfate, calcium carbonate, talcum powder or mica powder), and 30-45% resin (epoxy resin, alkyd resin, amino resin or acrylic resin), 20- 30% of solvents (alcohols, ketones or aromatic substances), 1-3% of transparent colorants and 0.5-1.5% of additives are mixed. The copolymers and pigments used in this patent application technology require good transparency, and the cost of raw materials is relatively high; on the other hand, the presence of various toxic components such as formaldehyde and epoxy resin in the raw materials is not good for the health o...
