Formula of stuffing for fireproof safe

Abstract

The invention discloses a formula of stuffing for a fireproof safe, which comprises main materials and auxiliary materials, wherein the main materials include 30%-50% of floating particles, 15%-14% of high alumina micropowder, 10%-20% of high alumina cement and 3%-8% of silicon micropowder, and the auxiliary materials include sodium tripolyphosphate and organic fibre, and the addition amounts of the sodium tripolyphosphate and the organic fibre respectively account for 0.10-0.20 percent and 0.06-0.12 percent of the total amount of the main materials. The stuffing adopts the floating particles, the high alumina micropowder, the high alumina cement and the silicon micropowder as the main materials, has the advantages of high temperature resistance, good heat insulation, high strength, convenient use and low cost when being used for making the safe, is difficult to burn under high temperature and can ensure the safety of important documents and articles inside the safe.

Description

technical field [0001] The invention relates to a formula of filler for a fireproof safe. Background technique [0002] The existing domestic fire-proof safes use refractory fillers, such as cement, vermiculite and other fire-proof and heat-insulating materials. Some foreign industrial countries are now using foamed cement fire-proof and heat-insulating materials, and some of our country also use foamed cement. Immature, unstable product control, uneven foam size and density, high density, bulky box, poor heat insulation and fire prevention effect, it is easy to cause the safe box to break and deform, and damage the items in the safe. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a formula for a safe filling material. The safe made of this filling material can effectively insulate heat and ensure that the box body will not be damaged under high temperature. [0004] In order to solve the above-mentioned techni...
