Problems solved by technology

[0005] The research on the existing transparent fireproof coatings in my country is mainly focused on the system that uses amino resins such as urea-formaldehyde resins, melamine-formaldehyde resins, melamine-formaldehyde-urea copolymer resins or modified amino resins as film-forming substances, but its flame-retardant effect is very poor. Ideal, difficult to use continuously for an extended period of time

preparation example Construction

[0034] The preparation steps of DOPOMA are:

[0035] In a three-neck flask equipped with a stirrer, a thermometer, and a reflux condenser, add a mixed solution of tetrahydrofuran and toluene of equal mass, DOPO and maleic anhydride are put in at a material ratio of 1:1.05, stir and heat, and the temperature is 84°C Backflow began to occur when the system was stable and reacted for 9 hours, and the color gradually deepened and turned green. After continuing to react for 24 hours, the color of the system was dark green. After 24 hours of heat preservation reaction, the reaction was stopped and cooled to room temperature. An appropriate amount of xylene was added to the solution and kept stirring. The system is layered, the lower layer is a dark green viscous liquid, and the upper layer is a light yellow clear liquid. The lower layer of viscous liquid is separated and washed with xylene for several times and placed in an oven at 120°C for 48 hours. Take out and cool to room temper...

[0043] Embodiment 1. Preparation of phosphorus-containing alkyd resin

[0044]In a 100ml four-necked flask, 28 parts of soy oil, 7.6 parts of pentaerythritol, 4.8 parts of phthalic anhydride and 3 parts of xylene were added. Nitrogen was passed, stirring was started, and the temperature was raised slowly. (Heat to 180°C within 30-40min). At 160°C, there was a sound of oil splashing and backflow. The system is a cloudy liquid. After a temperature of 170°C, the reaction system turned into a slightly yellow clear liquid after 20 minutes of reaction. When the system temperature reaches 180°C, start to keep warm for 40 minutes. Add 4.9 parts of DOPOMA in batches within 10 minutes after the end of the heat preservation. After the feeding is completed, slowly raise the temperature to 200°C for 30 minutes, and then slowly raise the temperature to 210°C. The final temperature for the heat preservation reaction is 210-220°C (do not rapidly heat up to 220°C to avoid bumping). As th...

[0045] Embodiment 2. Preparation of drier

[0046] Add 3g of cobalt isooctanoate, 10g of manganese isooctanoate and 10g of zirconium isooctanoate to 50g of 200# solvent oil, and disperse at a high speed of 3500r / min for 2 hours to obtain a drier for phosphor-containing alkyd resin transparent fireproof coating.

Abstract

The invention provides a phosphorous alkyd resin transparent fire retardant coating and a preparation method thereof. A formula of the phosphorous alkyd resin transparent fire retardant coating comprises the following components in percentage by weight: 62%-80% of phosphorous alkyd resin, 2%-3% of drier and 18%-35% of solvent. The preparation method comprises the steps of adding the phosphorous alkyd resin to the solvent at the formula ratio, dispersing for 20-40min, adding the drier, dispersing in a multipurpose dispersion and grinding machine for 10-20min, and obtaining the phosphorous alkyd resin transparent fire retardant coating.

Description

technical field [0001] The invention relates to the preparation technology of transparent fireproof paint. Background technique [0002] With the continuous improvement of economic development and people's living standards, the people's requirements for living are getting higher and higher, and the interior decoration of buildings has also developed accordingly. Wallpapers, carpets, and wood-structured decorative materials began to enter residents' homes, which also brought fire hazards. Coating a layer of fire-resistant coating on the surface of these materials is an effective measure to prevent fires. Although the development of non-transparent fire-resistant coatings is relatively mature, it will destroy the original decorative effect after being applied to the surface of decorative materials, especially for the protection of ancient buildings and cultural relics. And high-end furniture and so on. In order to maintain the original appearance of the decorations and play ...
