Description
Technical field
The present invention relates to a kind of fire retardant and preparation method thereof, particularly relate to a kind of paper that can promote and stop composite flame-retardant agent of combustibility and preparation method thereof.
Background technology
The material of paper determines it and belongs to inflammable material, in a lot of fields, due to the inflammability of paper, constrains the use of paper.Therefore the anti-flammability promoting paper is very necessary.Conventional processing mode the first be that the material of paper is selected, prepare fire retardant papers.The processing mode of the second fire retardant papers, for after preparing plain paper, uses fire retardant be coated with paper or spray, improves the anti-flammability of paper.
Stop burning paper, have many middle modes.The common theory in current this area is endothermic effect, dilution effect, depression effect and blanketing effect.They stop the mode of burning different, therefore also have different flame retardant effects.
Summary of the invention
The technical problem solved: common fire retardant is being applied to after in paper, the flame retardant effect of paper is still poor, limits the problem of the use approach of paper.
Technical scheme: in order to improve the fire resistance of paper, the invention discloses a kind of composite flame-retardant agent and preparation method thereof, composite flame-retardant agent is made up of according to weight ratio following composition: tricresyl phosphate is 7 ~ 9 parts, pentaerythrite is 4 ~ 7 parts, sodium metasilicate is 2 ~ 3 parts, Lauxite is 6 ~ 8 parts, ammonium phosphate is 4 ~ 6 parts, calcium bicarbonate powder is 3 ~ 5 parts, water is 82 ~ 88 parts.
A preparation method for composite flame-retardant agent, preparation method comprises the steps:, and calcium bicarbonate powder is pulverized by (1), and being crushed to calcium bicarbonate powder order number is 400 order ~ 500 orders, for subsequent use; (2) water intaking is 82 ~ 88 parts, heating-up temperature to 75 DEG C, add after temperature stabilization that pentaerythrite is 4 ~ 7 parts, sodium metasilicate is 2 ~ 3 parts, ammonium phosphate is 4 ~ 6 parts, stir after three kinds of component dissolves after adding pentaerythrite, sodium metasilicate, ammonium phosphate, be stirred to evenly; (3) mixed liquor being heated to again temperature is 90 DEG C, adds that tricresyl phosphate is 7 ~ 9 parts, Lauxite is 6 ~ 8 parts, is stirred to tricresyl phosphate and Lauxite and is dissolved to completely in mixed liquor and mixes; (4) finally 400 order ~ 500 object calcium bicarbonate powder being 3 ~ 5 parts is added in mixed liquor, cools, be prepared into composite flame-retardant agent after stirring.
The calcium bicarbonate powder order number added in the preparation process of composite flame-retardant agent of the present invention is preferably 500 orders.
The tricresyl phosphate added in the preparation process of composite flame-retardant agent of the present invention is preferably 8 ~ 9 parts.
The Lauxite added in the preparation process of composite flame-retardant agent of the present invention is preferably 8 parts.
Beneficial effect: brown paper, art paper composite flame-retardant agent of the present invention are carried out coating process, carry out drying, brown paper and art paper have possessed good fire resistance, and the standard of test is GB/T14656-93, and the brown paper afterflame time through processing is 0s, the time of burning is 0s, char length is 9mm to 10mm, and the afterflame time of art paper is 0s, and the time of burning is 0s, char length is 12mm to 13mm, has good fire resistance.
