Abstract

The invention discloses waterborne transparent fireproof paint for historic buildings and a preparation method of the waterborne transparent fireproof paint. The paint is prepared from, by weight, 25-30 parts of amino resin, 1-3 parts of waterborne polyvinyl alcohol powder, 3-5 parts of ethylene-vinyl acetate copolymer, 5-10 parts of polysiloxane, 18.5-34.5 parts of fire retardant, 10-15 parts of pentaerythritol, 1-5 parts of phytic acid, 0.5-1.5 parts of triethanolamine, 2.1-3.5 parts of additives, 5-10 parts of a wood stabilizer and 10-29 parts of water. The method includes steps of raw material weighing, primary mixing and secondary mixing. By condensation polymerization of active polysiloxane emulsion and active phosphonate, fireproof performance of the paint is improved, coating transparency is realized, original appearances of materials can be kept, and the paint is less prone to cracking and excellent in weather resistance; since a main component of the paint is dry powder, storage life of the paint is effectively prolonged; due to addition of the waterborne wood stabilizer and the phytic acid in the fireproof paint, rotten and deformed wood materials are protected effectively.

Description

technical field [0001] The invention belongs to the technical field of building fireproof coatings, and in particular relates to a water-based transparent ancient building fireproof coating and a preparation method thereof. Background technique [0002] The Chinese nation has a splendid civilization of five thousand years, and its history and culture have been passed down for a long time. Ancient buildings and ancient dwellings are artistic treasures with a long history, marking the civilization level of a country, witnesses of human history, and the common precious wealth of all mankind. However, due to some characteristics of its mostly wooden structure, its flame retardancy is poor. Fires often occur in ancient buildings and ancient dwellings all over our country. Once these national treasures are caught in fire, they will never be restored. [0003] Due to the lack of effective "active" protection means, most of them adopt "passive" spraying, fire hydrants and other met...
