Embodiment 1

[0017] Preparation of titanium dioxide fiber: Weigh 2g of PVP, add 18g of ethanol, when the PVP is completely dissolved, then add 16g of acetic acid and 8g of tetrabutyl titanate in turn, stir for 30min, and then vibrate in an ultrasonic cleaner for 10 minutes to obtain a precursor solution. The receiving distance of the electrospinning device was adjusted to 20cm, the negative voltage of spinning was 1500V, the advancing speed was 0.006mm / s, and then different positive voltages of 18kv were applied. Collect with dry glass flakes, the receiving time is 5min, and obtain titanium dioxide fibers with a diameter of 100-150nm and an aspect ratio of 50-70.

[0018] Titanium dioxide fiber 10, phenol 60, formaldehyde 40, sodium hydroxide 10, glutaraldehyde 10, chopped polyester fiber 10, silane coupling agent 1, blowing agent n-pentane 1, curing agent AB quinoline 6 parts of compound, 4 parts of surfactant.

[0019] After the raw materials are mixed and the polymerization reaction is...

Abstract

The invention provides a titanium dioxide fiber modified phenolic resin thermal insulation material. Raw materials of the thermal insulation material comprise raw materials for preparing phenolic resin, and titanium dioxide fibers, and the raw materials of the thermal insulation material are uniformly mixed, polymerized and molded to prepare the resin. Impact experiments show that the titanium dioxide fibers added according to the fiber reinforcement principle improve the strength of the phenolic resin thermal insulation material and degrade the indoor environment, so the requirements of environmentally friendly buildings are met.

Description

technical field [0001] The invention belongs to the technical field of environmental protection building materials, and in particular relates to a high-quality thermal insulation material. Background technique [0002] In recent years, due to the emphasis on building environmental protection and external wall insulation, more and more new building insulation materials have been developed and applied to new buildings. Phenolic resin insulation material is an organic polymer hard aluminum foil resin product, which is a phenolic resin material foamed from thermosetting phenolic resin, due to its high closed cell rate, good thermal insulation performance and low thermal conductivity. , and has excellent characteristics such as water vapor permeability and water resistance, and has the characteristics of light weight, high fire resistance, non-combustibility in case of open flames, no dripping, non-toxic and smoke-free, and can be used in low temperature environments (-196 ~ 200 ...
