Embodiment 1

[0013] Modification of nano-titanium dioxide: in parts by weight, take 12g of nano-titanium dioxide, disperse it in toluene, then add 7g of silane coupling agent KH550, then raise the temperature to 100°C at a rate of 10°C / min, and stir for 1h. The surface-modified nano titanium dioxide powder is obtained through centrifugation, washing and drying.

[0014] Preparation of composite resin: in parts by weight, take 8 parts of glutaric acid, 10 parts of styrene, 10 parts of n-butyl methacrylate, and 10 parts of methyl methacrylate, add them to the reactor in turn, and then add OP- 2 parts of 13, 2 parts of TX-13, 15 parts of surface-modified nano-titanium dioxide powder, after stirring evenly, add 1 part of sodium persulfate, heat up to 80 °C at a rate of 10 °C / min, stir for 20 minutes, and then add over 1 part of sodium sulfate, after heating up to 90°C, stir and react for 2 hours, then add 5 parts of glutaric acid, 5 parts of styrene, 5 parts of n-butyl methacrylate, 5 parts of...

Abstract

The invention relates to a production method for a heat-insulating flame-resistant material. The production method has the advantages that specific monomers and ratios are adopted, and nano titanium dioxides are coated with polymers by a high-temperature polymerization process, so that agglomeration of nano components in the flame-resistant material is avoided effectively, and dispersity and stability of the nano titanium dioxides in the flame-resistant material are improved; in addition, a synergistic effect is achieved through compounding of modified nano titanium dioxide powder, composite resin, docusate sodium, cyclododecanone, four parts of propylene glycol n-butyl ether and N,N-diethyl aniline, and accordingly, flame resistance and heat insulation of the material are improved greatly; the flame-resistant material acquired according to the specific ratios has various excellent performance such as heat insulation, wear resistance, rigidity, strength and adhesiveness; the production method for the heat-insulating flame-resistant material is simple and easy to operate and the material is easy to produce industrially.

Description

technical field [0001] The invention relates to a preparation method of a heat-insulating and flame-retardant material. Background technique [0002] Energy saving and consumption reduction is an important pursuit goal of today's construction industry, and it is also an important indicator to measure the technical level of architectural design and construction enterprises. Ordinary flame-retardant materials for exterior walls will absorb infrared rays in sunlight and convert them into heat energy, causing the temperature of the surface layer to rise. raised. Theoretically speaking, as long as the heat radiation can be effectively reflected or blocked, the effect of heat insulation can be effectively achieved, such as the use of silicate materials. Classic wall thermal insulation materials include phenolic resin synthetic materials, polyurethane materials, glass fiber materials, aluminum silicate rock wool, mineral wool, rubber and plastic, cork, perlite, etc. These materi...
