Abstract
The utility model relates to a non-twisted glass composite yarn for composite cement bag, which comprises glass fiber bundles formed by combining multi-strand glass strand without twisting and a layer of elastic body polymer layer which is coated on the outside of the glass fiber bundles. A layer of water soluble adhesive layer can also be coated on the outside of the elastic body polymer layer. The composite paper bag made of the utility model has the advantages of high tensile strength, low brittleness, and good bend prevention performance. The non-twisted glass composite yarn has the advantages of non-perishable fluffing and non-perishable end broken after coated the coating layers. At the winding process of the composite paper bag manufacture, the number of times of the shutdown caused by the broken ends can be reduced, the output can be increased, and the consumption of the non-twisted glass composite yarn can be saved.
Description
The utility model relates to a kind of structure of making the glass zero twisted yarn that the complex cement packing bag uses.
The complex cement packing bag utilizes two layers of kraft paper therebetween one deck fibrous reticulum to make, owing to use filamentary material to do stiffening web, the tensile strength of paper bag increases, the damaged minimizing.Chinese patent 87215557.9 has been introduced and has a kind ofly been done the cement packing paper bag of stiffening web with the glass zero twisted yarn, because glass fibre tensile strength height, the paper bag resisting breakage performance of making is good.But because glass fibre fragility is stronger, not anti-bending, after the tackiness agent drying outside glass fibre, it is crisp firmly that paper bag just becomes, frangibility when crooked, so though the tensile strength height, fracture resistance is not so good.
The purpose of this utility model is to propose the glass zero twisted yarn that the good complex cement packing bag of a kind of fracture resistance is used.
The non-twist composite yarn of this glass comprise by the multiply glass strand without twisting and close the glass fiber bundle that forms, coated has one deck elastomer polymer coating outside glass fiber bundle.
The non-twist composite yarn of this glass is because coated outside one deck elastomer coating, so after making paper bag, tackiness agent drying, ORGANDY still can keep certain flexibility, thereby the fragility of paper bag is reduced, and fracture resistance greatly improves.In addition, be difficult for fluffing on the glass zero twisted yarn external parcel after the coating, also be difficult for broken end, when making compound paper bag, can reduce the shutdown number of times that causes because of broken end, improve output with the winding legal system.Coating combines into glass fibre as a whole, has improved tensile strength, thereby adopts less yarn can reach specification of quality.
Accompanying drawing is the cross-sectional configuration figure of the non-twist composite yarn of this glass, and (1) is glass fibre among the figure, and (2) are elastomer coating, and (3) are the water-soluble binder layer.
The elastomer polymer coating of the non-twist composite yarn of this glass can adopt various material to make, for example can adopt the natural rubber coating, the mixture coating of the mixture coating of neoprene coating, polyvinyl alcohol and natural rubber, polyvinyl alcohol and chloroprene rubber.
Introduce the making method of this elastomer polymer coating below.
1, natural rubber or neoprene coating: with solid content is that to be diluted with water to solid content be 5% emulsion for 60% nature rubber latex or neoprene latex, with ORGANDY instantaneous passing through in this emulsion, adsorbed emulsion on the ORGANDY, it is passed through in the fixed length precipitation bath of 30% aqueous hydrochloric acid, emulsion on the ORGANDY is promptly dewatered and is solidified, form one deck softish elastic coating, after washing, promptly become the non-twist composite yarn of glass of flexible polymeric coating again.
2, the mixture coating of polyvinyl alcohol and natural rubber or chloroprene rubber: with solid content is that 6% nature rubber latex or neoprene latex and solid content are that 4% polyvinyl alcohol water solution is mixed mutually with the weight ratio of 1:1, make ORGANDY instantaneous passing through in above-mentioned solution, adsorbed mixed emulsion on the fibrous bundle, again this ORGANDY is passed through in the mixed mutually acid inorganic salt precipitation bath of making of 30% aqueous sodium persulfate solution and 10% aqueous sulfuric acid, mixed emulsion on the ORGANDY promptly dewaters and solidifies, again after washing.
The outside of the elastomer polymer coating (2) of the non-twist composite yarn of glass can also be coated with last layer water-soluble binder layer (3).Coating adhesive again when making cement packing paper dress only needs ORGANDY is passed through from water like this, makes it moistening, just has viscosity, can carry out bonding operation.
One of compound method of above-mentioned water-soluble binder is: 10 parts of starch, 3 parts in urea, 1 part of SODIUMNITRATE, 10 parts in water, above-mentioned raw materials is fully mixed, under 30-40 ℃ of temperature, constantly stir, thing to be mixed is converted into from thin slurries and adds 30 parts in water again after thick, be warming up to 96-98 ℃, constantly stir about is 1 hour, is cooled to normal temperature.This Starch Adhesive solid content is about 25%, viscosity is about 1400 centipoises.With 10 parts of this Starch Adhesives and solid content is chloroprene rubber or 4 parts of uniform mixing of nature rubber latex of 60%, adds 5 parts in water again, and the tackiness agent, viscosity that are diluted to solid content about 25% are about 800 centipoises.This tackiness agent is water-soluble binder, elastomer polymer coating and kraft paper all there is good adhesive capacity, and it is cheap, the glued membrane that forms is soft, with the outside of its coated to the elastomer polymer coating of the non-twist composite yarn of glass, after the drying, ORGANDY is wound into tube, is finished product.
Two of the compound method of water-soluble binder is: with solid content is that 2 parts of the chloroprene rubber of 10 parts of 12.5% polyvinyl alcohol water solutions and solid content 60% or nature rubber latexes are evenly mixed.This kind tackiness agent price is also cheap, and the glued membrane quality of formation is also good.
