Description
Technical field
The present invention relates to a kind of lightweight foam material, particularly a kind of fireproof filling material and preparation method who utilizes the phosphatization waste residue, waste water and the transfer printing waste paper that produce in the metal door production processes such as antitheft door, fire door, steel entering house door to produce fire door as raw material.
Background technology
At present, in the technological process of production of producing metal door such as antitheft door, fire door, steel entering house door, get rusty and make paint have a better adsorptive power for preventing the metallic surface, all must carry out pickling degreasing phosphatization processing of rust removing, in this process, all have the phosphatization waste residue of metal-conditioning treatment postprecipitation and waste water to discharge metal door.Because the chemical feedstocks that adds in the phosphatization aqueous solution is more, so just contain multiple harmful Chemical Composition in waste residue that emits and the waste water, mainly contain five phosphorus oxide in the waste residue, secondary calcium phosphate, monocalcium phosphate, ferric oxide, multiple components such as polymer alumina, polyacrylamide mainly contain a large amount of phosphorus in the waste water.For qualified discharge, manufacturing enterprise need drop into substantial contribution, environmental protection equipment, personnel and water treatment agent waste residue and waste water are handled, and treated waste water can reach the urban sewage discharge standard basically, but still contains phosphorus in a small amount in the sewage of discharging; To the waste residue that precipitates in the water treatment procedure, manufacturing enterprise generally transports to the brick field and adds in the yellow mud, and the filling raw material as brickmaking carries out burning disposal with waste in the process of baking bricks.But bad enterprise is also arranged,, directly phosphorized waste water is outwards discharged without this procedure of water treatment.Owing to contain a large amount of phosphorus in the phosphorized waste water, outwards the phosphorized waste water of discharging is to subterranean percdation, the polluted underground water resource.
In the technological process of production of producing metal door such as antitheft door, fire door, steel entering house door, can produce transfer printing waste paper after the shop front pattern transfer, because this waste paper can not recycling, therefore how to handle and also become burden, have enterprise to burn, and the enterprise that has end up with nothing definite with regard to directly pouring the refuse tip into through after drying.The problems referred to above not only cause the wasting of resources, do not meet the policy of national energy-saving and emission-reduction, comprehensive utilization, and contaminate environment.
And metal door such as the antitheft door of producing at present, fire door, steel entering house door generally to select honeycomb paper and Calucium Silicate powder plate holder aluminium silicate wool for use be stopping composition.The weak point that honeycomb paper exists is: meeting fire can burn, and does not have fire resistance, and sound absorption sound insulation and heat preservation and insulation are poor, and moisture-sensitive is met water and can be softened, and the waterproof water resistance is poor.The weak point that Calucium Silicate powder plate holder aluminium silicate wool exists is: fire resistance rating is low, meet high temperature and can produce fusing, do not have anti-fire action, the production cost height, asbestos needle-holding hand, dust suck the human body infringement big, and State Environmental Protection Administration just clearly stipulated in 2005 for this reason, must not contain asbestos in the household article, tackiness agent must not contain objectionable impuritiess such as formaldehyde, benzene.Metal door such as antitheft door, fire door, steel entering house door press for a kind of fire-protection rating height, physical strength is good, production is easy for installation, cost is low type gate inner filling material.
For this reason, many scientific research institutions, manufacturer and knowledgeable people have constantly carried out R and D at the problems referred to above that exist, and do not improve way preferably but have as yet so far.
Summary of the invention
My company drops into a large amount of man power and materials for solving the problem of above-mentioned existence, and development research has been carried out in the comprehensive utilization of the phosphatization waste residue, waste water and the transfer printing waste paper that produce in the production metal door process.Through effort more than a year, my company develops and a kind of phosphatization waste residue, waste water and waste paper is fully utilized stopping composition and the preparation method who produces novel fire door, for my company on the road of having walked out a light aspect energy-saving and emission-reduction, environment protection treating, the comprehensive utilization.The objective of the invention is to utilize the phosphatization waste residue, waste water and the transfer printing waste paper that produce in the metal door production process as raw material, produce a kind of unit weight at 200～500kg/m
3Between the fire door light filler, these goods have physical strength height, in light weight, advantages such as fire resistance rating is high, good, the weathering resistance of sound absorption soundproof effect is strong, heat insulation heat preservation energy-saving, production are easy, nontoxic no radiation.These goods can be widely used in metal door industry, building material industry and relevant industries.
The technical solution adopted for the present invention to solve the technical problems, it comprises waste residue, transfer printing waste paper, water-resisting agent, water reducer and the whipping agent of magnesium oxide, sal epsom, metal-conditioning treatment postprecipitation, and unit weight is at 200～500kg/m
