Abstract
The preparation process of asbestos and non-asbestos latex sheet includes the following steps: dispersing asbestos or non-asbestos fiber in water and adding stuffing to pulp; adding carbon black and mixing homogeneously; adding latex, sulfur and antiager and mixing homogeneously; feeding the homogeneously mixed material to front flowing system of papermaking machine, adding cationic polyacrylamide as retention aid before the pulp flushing pump, pressure sieve or high position tank, and adding bentonite before pulp flowing tank; and final making sheet and drying. The addition of proper amount of cationic polyacrylamide as retention aid and bentonite makes the pulp possess excellent water filtering performance, lowers the beating degree of the pulp to below 50 deg SR and produces excellent dewatering and forming performance of the material in the net.
Description
Technical field
The invention belongs to the crossing domain of rubber industry and paper industry, particularly a kind of asbestos and method for preparing non-asbestos latex sheet.
Background technology
Traditional asbestos rubber sheet mainly be with mixing mould pressing process produce (therefore, its product also is asbestos packing sheet), rubber adhesive needs through organic solvent dissolution in the production, mix with asbestos fibre, other compounding ingredient and filler then, make material for making clothes, make sealing plate material through two roller Cheng Zhangji calenderings again.This method is because energy resource consumption is big, it is big to pollute, efficient is low, and is superseded substantially at western developed country, turns on substantially at present that (its product is asbestos latex board with paper process production, be called for short collecting plate), promptly earlier asbestos fibre is disperseed in water, then, making beating adds and fills out, and adds glue and various auxiliary material, at last, through approach system, the moulding of on the paper machine, manufacturing paper with pulp, squeezing, drying cuts, packing, warehouse-in.The sheet material specification that adopts this production technology to produce is versatile and flexible, the sheet material softness, size and stable performance, even, processing and convenient transportation, and this production method need not with an organic solvent, asbestos are wet-treating, therefore, the production security height, environmental pollution is few, in addition, the production efficiency of this method is higher than mixing die pressing far away.
But, because the water filtering performance of slurry is very poor in the asbestos latex board production process, beating degrees such as used asbestos fibre, filler very high (beating degree at 70 ° more than the SR), therefore, the slurry that has caused these raw materials to form is very difficult in the web part of paper machine dehydration, the paper machine can't normally be moved, can only on step cylinder mould machine, produce, can't on long mesh paper making machine, carry out serialization production.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, providing a kind of can improve the wet end dehydrating effect in collecting plate is produced, and makes the production of collecting plate produce asbestos and the method for preparing non-asbestos latex sheet that transforms to continuity method from batch process.
For achieving the above object, the technical solution used in the present invention is: at first, asbestos or non-asbestos fiber are disperseed in water, making the asbestos after the dispersion or the mass concentration of non-asbestos fiber is 1-30%, adding with respect to asbestos or non-asbestos fiber mass ratio then is the filler of 1-90%, changes 50-3000 and change making beating under 450 rev/mins rotating speed; Secondly, adding with respect to asbestos or non-asbestos fiber mass ratio is the carbon black of 0-60%, mixes; And then to add with respect to asbestos or non-asbestos fiber mass ratio be the latex of 2-40%, the sulphur of 0.1-20% and the age resistor of 0.01-15%, mixes; At last, the raw material that mixes is sent into approach system before the paper machine net, before net, add cationic polyacrylamide retention agent before the fan pump of approach system or pressurized screen or the header box with respect to the mass ratio 0.01-5.0% of asbestos or non-asbestos fiber, before head box, add bentonite with respect to the mass ratio 0.05-10.0% of asbestos or non-asbestos fiber, at last, the moulding of on the paper machine, manufacturing paper with pulp, dry getting final product.
Owing to add an amount of cationic polyacrylamide retention agent before the fan pump of the present invention's approach system before collecting plate is produced gauze or pressurized screen or the header box, then, before head box, add proper amount of bentone, obtain good water filtering performance after making the collecting plate raw material deliver to web part of paper machine through head box stream, make the beating degree of online raw material reduce to 50 ° below the SR, thereby make raw material produce good dehydration and molding effect at wet end.
