Description
Technical field
The invention belongs to pulp and paper technology field, particularly a kind of composite flame-proof paper base material and preparation method thereof.
Background technology
Paper is generally formed by the string system of copying, and is combustible material, along with social development, need to use fire retardant papers and paper substrate, as packaging material, electrical apparatus insulation material, building and ornament materials etc. in increasing place.Through the paper products of flame treatment, be fire retardant papers or paper base material, possess difficultly fire, fire, high temperature resistant, but the characteristics such as cigarette are the paper base materials with specific use.The method of producing at present string fire retardant papers or paper substrate mainly contains following three kinds:
1. infusion process.Exactly paper is flooded to the method for absorption fire retardant by retardant solution.The method can be produced some fire retardant papers, but because paper or the paper substrate of infusion process need adsorb a large amount of fire retardants, large to the performance impact of paper own, as shortcomings such as fire retardant papers moisture absorption are strong, distortion is large, intensity is low, so narrow application range.
2. surface-coated method.Exactly fire retardant is applied over to the surface of paper, makes fire retardant papers or paper substrate.The fire retardant of rubbing method mainly concentrates on the surface of paper, and its surface flame-retardant effect is relatively better, but can not give paper inner anti-flammability, and because rubbing method is used a large amount of organic binders, so flame retardant effect is not ideal enough.Rubbing method fire retardant papers can only be applicable to need paper or the paper substrate of coating in addition, to not needing in a large number paper or the fire-retardant of paper substrate of coating to be suitable for.
3. in slurry, add the method for fire retardant.In slurry, add various water-insoluble fire retardants, mix and copy into fire retardant papers or paper substrate with string.This method is simple, but fire retardant addition is large, large on the physical property impact of body paper.
In sum, the method for production fire retardant papers has larger impact to the physical property of body paper own at present, and this has just had a strong impact on quality and the use of fire retardant papers or paper substrate.
Summary of the invention
The object of the invention is to provide a kind of composite flame-proof paper base material and preparation method thereof, with what overcome that prior art exists, the physical property of body paper own is had to the deficiency of considerable influence.
The problem existing in order to overcome prior art, the invention provides a kind of preparation method of composite flame-proof paper base material, raw material type and parts by weight in preparation process are as follows, needlebush pulpboard: leaf wood pulpboard: Fanglun slurry cake: composite flame-proof filler: APP is 1:0.5～1:0.04～0.15:0.2～0.6:0.05～0.1
Its preparation process comprises the following steps:
1. needlebush pulpboard and leaf wood pulpboard are made to concentration and are 3～6% paper pulp;
2. to make concentration be 0.1～0.5% Fanglun slurry cake suspension to Fanglun slurry cake;
3. by the degree of polymerization, be that more than 500 APP is dissolved in hot water, the diatomite that is 1:0.5～1 APP and diatomite ratio of weight and number adds in APP, be uniformly mixed 1～2 hour, make mixing mud, after mixing mud is dried, pulverized and sieved, obtain the compound fire-retardant filler of APP/diatomite;
4. needlebush paper pulp, leaf wood paper pulp and Fanglun slurry cake suspension are mixed in stock proportioner, be pumped to header box, the composite flame-proof filler that is 1:0.2～0.6 with composite flame-proof filler weight portion rate needlebush pulpboard mixes with above-mentioned slurry, and add the retention agent of mixed pulp weight 0.01-0.04%, be diluted with water to 0.3～0.6% concentration, copy and make body paper;
5. by the degree of polymerization, be more than 500 APP with hot water dissolving, be prepared into concentration and be 1～5% the water-based printing aqueous solution;
6. the water-based printing aqueous solution that the APP that is 1:0.05～0.1 needlebush pulpboard and APP ratio of weight and number is made, mode with intaglio press with water color ink printing, two-face printing is coated on paper, and dry rear formation is quantitatively 60～120 g/m
2paper substrate finished product.
A kind of composite flame-proof paper base material being made by above-mentioned preparation method.
The present invention utilizes Fanglun slurry cake for fire resistance fibre, with the compound fire-retardant filler of APP/diatomite and high polymerization degree APP solution, it is main fire retardant, by string, Fanglun slurry cake and composite flame-proof filler, mix copy paper and utilize intaglio printing principle and the technology of water color ink, make composite flame-proof paper base material.The present invention utilizes heat-resisting quantity and the anti-flammability of Fanglun slurry cake, effectively improves the anti-flammability of paper base material by adding a small amount of Fanglun slurry cake; Utilize APP coated diatomite surface and at the intrapore efficient adsorption of diatomite, and make full use of APP and diatomaceous cooperative flame retardant effect, make efficient composite flame-proof filler, utilize water color ink intaglio printing technology simultaneously, do not using under the condition of organic binder, the APP aqueous solution is printed and is applied to paper, utilize the high flame retardant of high polymerization degree APP, make paper base material reach the fire-retardant object of composite monolithic.
The present invention has following advantage and effect with respect to existing fire retardant papers production technology:
1. composite flame-proof paper base material provided by the invention, amount of flame-retardant agent is few, and the retention of fire retardant in paper substrate is high, good flame retardation effect.
2. the invention solves existing fire retardant papers affects large shortcoming to the physical property of body paper, can effectively keep the Main physical intensity indexs such as tensile strength of body paper, rear handling ease.
3. the invention solves the shortcoming of existing fire retardant papers narrow application range.The paper base material of preparation can directly be used, also can be used as the fire retardant papers sill of rear processing use, on the paper base material basis that can prepare in the present invention, according to the instructions for use of different fire proofings be coated with, printing, embossing, the rear processing such as compound processes, and greatly improved its scope of application.
