[0030] Preparation of inorganic powder:

[0031] Put expanded graphite and sericite into a pulverizer at a mass ratio of 2:1, pulverize at a speed of 900r / min for 1 hour, and put the ground material into a planetary ball mill after pulverization. After grinding for 20 minutes under the condition of 120 r / min, pass through a 50-mesh sieve to obtain inorganic powder.

[0032] Preparation of modified inorganic powder:

[0033] Collect kelp and put it into a grinder, grind for 20 minutes to obtain kelp powder, mix the kelp powder with the above-mentioned inorganic powder in a mass ratio of 1:5 to obtain a substrate to be fermented, and mix 14 parts of the fermentation substrate by weight. Put the material, 2 parts of river bottom sludge and 4 parts of distilled water into the fermenter, seal the mouth of the fermenter, place the fermenter in a greenhouse with a temperature of 20°C, and ferment for 1 week to obtain modified inorganic powder for later use.

Abstract

The invention relates to a preparation method of a waterproof fireproof paint, and belongs to the technical field of paint preparation. According to the preparation method, expandable graphite and sericite are taken as raw materials to form a carbonaceous layer with excellent bonding effect with a building substrate; sea-tangle is adopted as a raw material to provide an obtained fireproof paint with water resistance; glass fiber excellent in thermal insulation effect is adopted to improve the water resistance of the fireproof paint greatly, glass fiber and an alkali solution are reacted to improve the bulking capacity of glass fiber, glass fiber thermal insulation performance flame resistance are improved greatly, and the thermal insulation performance flame resistance of the fireproof paint are improved; rice husk is taken as a raw material to obtain lignin, lignin is decomposed into cellulose for bonding and stretching effect in the fireproof paint; a modified inorganic matter powder, standby modified glass fiber, the above modified phenolic resin, and egg white protein are mixed and stirred to form a structure similar to a foam thermal insulation layer, so that the thermal insulation performance flame resistance of the fireproof paint are improved greatly, and a promising application prospect is achieved.

Description

technical field [0001] The invention relates to a preparation method of a waterproof and fireproof coating, which belongs to the technical field of coating preparation. Background technique [0002] With the continuous and rapid growth of my country's economy and the massive construction of infrastructure, people's living standards have improved and their awareness of environmental protection has gradually increased. In modern home decoration, the use of various flammable materials is becoming more and more common. In recent years, several fires have occurred across the country, causing a large number of casualties and property losses. Therefore, building fire protection has become the main technical index affecting building safety performance. [0003] A very common fire prevention treatment method is to use fire retardant coatings. Coating fire-resistant coatings on the interior and exterior walls of buildings not only plays a decorative role on materials, but also prolo...
