Preparation method of novel flame-retardant thermal insulation board

Abstract

The invention discloses a preparation method of a novel flame-retardant thermal-insulation board, and belongs to the field of building materials. The preparation method comprises the following steps:1, preparation of flame-retardant slurry: A, preparing a flame-retardant matrix; B, mixing 50-100 parts by weight of the flame-retardant matrix obtained in the step A with 10-12 parts by weight of calcium oxide, and stirring to obtain gel; C, adding 20-55 parts by weight of heat insulation particles into the gel obtained in the step B, and uniformly stirring the mixture; D, adding 5-10 parts by weight of polyphenyl alkene foam on the basis of the step C, and uniformly stirring the mixture again; E, adding 1-3 parts by weight of an anti-aging agent SP on the basis of the step D, and uniformly stirring the mixture again to obtain required flame-retardant slurry, and then performing film compression and maintenance steps to obtain the required flame-retardant thermal insulation board.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a novel flame-retardant and heat-insulating board. Background technique [0002] Most building insulation materials on the market are mostly organic substances, such as polyurethane foam, expanded polystyrene particles, and foamed phenolic formaldehyde. These organic substances have many advantages as building insulation materials. The materials are lighter, but the insulation effect is good, and the price is cheap. The fly in the ointment is that this type of organic material is flammable, once there is an open flame, it is very easy to cause irreparable losses due to fire. Therefore, it is very necessary to develop a thermal insulation material that is flame retardant, has good thermal insulation effect, low cost, light weight, convenient installation, energy saving and environmental protection. Contents of the invention [0003] In order to...
