[0002] At present, the known organic fireproof blockages are mainly obtained by adding halogen flame retardants to obtain excellent flame retardancy. Although halogen materials have good flame retardancy effects, they will release a large amount of smoke and hydrogen halide gas when a fire occurs. , these smoke and

Abstract
The invention relates to a making method of non-expansion non-bittern organic fireproof block material, which comprises the following steps: dispensing the raw material according to weight percent with 20%-50% aluminum hydroxide, 10%-25% zinc borate, 20%-40% porcelain powder, 5%-10% alumina silicate fiber, 2%-8% iron oxide red, 13%-20% polyester resin, 1%-2% coumarone resin, 1%-2% xylenol resin, 3%-6% dibutylphthalate, 1%-5% functional agent, soaking the coumarone resin 1%-2% and the xylenol resin in the dibutylphthalate for 24 hours; adding the polyester resin and the functional agent to stir to be sticking resin; adding the aluminum hydroxide, the zinc borate, the porcelain powder, the alumina silicate fiber, the iron oxide red into stirrer to stir for 10-15 minutes to form premix stuffing; squeezing to form shaping through force out machine after blending and stirring the sticking resin and the premix stuffing to form mission of viscous soft. The invention overcomes the problem that current fire-proof block can be produced irritating gas and smog under effect of fire hazard, which avoids toxic hydrogen halide gas to injury human body and corrode device effectively.
Description
1. Technical field [0001] The invention relates to a fireproof blockage, in particular to a method for manufacturing a non-expandable halogen-free organic fireproof blockage. 2. Background technology [0002] At present, the known organic fireproof blockages are mainly obtained by adding halogen flame retardants to obtain excellent flame retardancy. Although halogen materials have good flame retardancy effects, they will release a large amount of smoke and hydrogen halide gas when a fire occurs. , these smoke and hydrogen halide gases will irritate the human eyes and respiratory system, causing symptoms such as dizziness, coma, difficulty breathing, suffocation and death, and also hinder the fire fighting and rescue work of firefighters and rescuers, and can cause electrical system switches and other metal objects of corrosion. 3. Contents of the invention [0003] In order to overcome the disadvantages of existing organic fireproof blockages containing halogens and toxic...
