Abstract
The present invention relates to a production process for glass fiber gum dipping threads, which comprises the following main process steps: firstly, dipping glass fiber stranded threads in gum; then, drying to make the dipped gum form films, and successively twisting a plurality of glass fiber stranded threads into a thread; finally, dipping the whole thread in gum, and drying to make the gum dipped layer integrally form a film outside the thread. The process provides a high strength glass fiber thread formed by twisting a plurality of glass fiber stranded threads which are formed by combining glass fiber monofilament splicing threads. The process is advanced, and the product has the advantages of higher adhesive strength and stronger tensile property and can be used in high strength operation occasions.
Description
Technical field
The present invention relates to a kind of production technology of glass fibre rope yarn, more particularly relate to a kind of production technology and goods thereof of glass fiber dipped rope yarn.
Background technology
The glass fibre rope yarn can be used in the multiple industrial occasions, and as V-belt, band and conveyer belt etc. synchronously, rope yarn can make the stress and strain that they stand in process to be produced, and certain intensity is provided.Usually the glass fibre rope yarn is that twisted forms after being coated with upper glue layer by the glass fibre monofilament.Naked glass fibre itself is smooth rod type element substantially, and its surface has high-hydrophilic, thereby, in general, lack the gummed property between naked glass fibre and bulk material, cause between glass fibre and bulk material disconnected from each other easily, so can not make fiberglass reinforced articles.Usually on the surface of naked glass fibre, be coated with the thin sizing material that last layer matches with it, thereby improve the gummed relation between glass fibre and the bulk material.In addition, glue-line also can make glass fibre avoid grinding loss, plays the certain protection effect.After being coated with upper glue layer, can strengthen the affinity of itself and bulk material (as rubber).In the disclosed production process about rope yarn, strand makes finished product then only through a gluing behind twisted.It is a kind of improvement of the high-speed process of glass fiber dipped rope yarn and Industry thread, this invention provides a kind of improvement of the high-speed process of production high-performance multi-end polyester line, and the mat finish between 35 microinch to 120 microinch and the drawing point positioner from the second draw roll cartridge system advance yarn and yarn approximately to adopt the roller surface roughness value that has arithmetic mean of instantaneous value on the guiding roller.This combination makes multi-filament be kept acceptable high level by the single device and the yarn engineering properties with the roller of regulating of advancing, stretch in advance.Though this technological operation design is comparatively reasonable, the intensity of the rope yarn of being produced is comparatively general, often can not be applicable to the special occasions of high-intensity operation.
Summary of the invention
One of purpose of the present invention is to solve to be easy to generate stress and easy loose technical problem in the existing glass fibre rope yarn production process, and a kind of production technology of glass fiber dipped rope yarn is provided.
Two of purpose of the present invention provides a kind of each strand in conjunction with firm, and the glass fiber dipped rope yarn that is difficult for being worn.
These and other purposes of the present invention will further be set forth by following detailed description and explanation.
The production technology of glass fiber dipped rope yarn of the present invention, glass fiber precursor is carried out the impregnation first time earlier, oven dry then, make impregnation become interior rubber shoe latex layer, obtain fiberglass strand, more some fiberglass strands are twisted into rope yarn, adopt left and right directions to piece together line, the whole-root rope line carries out the impregnation second time then, oven dry, rubber shoe latex layer outside the whole one-tenth outside described rope yarn.
Further, in the production technology of glass fiber dipped rope yarn of the present invention, for the first time during impregnation, the weight ratio of glass fiber precursor and glue is 1: 0.18～0.25; In second time during impregnation, the weight ratio of strand and glue is 1: 0.20～0.30, like this in rubber shoe latex layer certain gummed power and intensity both can be provided, again easily by twisted.
High strength glass fiber impregnation rope yarn of the present invention, form by many fiberglass strands (2) twisting, described fiberglass strand (2) is to piece together the line adduction by glass fiber precursor (3) to form, the skin of glass fiber precursor (3) is enclosed with interior rubber shoe latex layer (4), some strands (2) are twisted into rope yarn (1), and are enclosed with whole outer rubber shoe latex layer (5) in the periphery of rope yarn (1).
In high strength glass fiber impregnation rope yarn of the present invention, described fiberglass strand (2) is that the no twist or the twist are lower than 20 glass fiber bundles of twisting with the fingers, and the twist of described rope yarn (1) is 40～120 sth. made by twisting; The diameter of described glass fiber precursor (3) is 8～10 microns, number of share of stock is 2～19 strands, different number of share of stocks can make its curtain cotton rope obtain different intensity, and strand can be more or less freely on the one hand is twisted with the fingers and be in the same place, twist with the fingers on the other hand with after rope yarn will have very high intensity; The external diameter of rope yarn (1) is 0.3～2.7 millimeter, and outer glue-line is embedded in the inner glue layer.In this scope, rope yarn has pliability and bond peel strength, tear fracture intensity preferably, and the gained rope yarn has proper intensity, when using as products such as V-belt, conveyer belts, can strengthen its tensile strength and inherent adhesion strength greatly.
The production technology of glass fiber dipped rope yarn of the present invention is at first carried out impregnation to glass fiber precursor and is got each strand, after piecing together line, carry out the impregnation second time again through each strand behind the impregnation for the first time, make each strand combine together, thereby make the bulk strength of curtain cotton rope and smoothness be greatly improved and improve that this technology has very strong advance.The gained rope yarn is formed by many fiberglass strand twisting, and strand has interior rubber shoe latex layer, and this glue-line can well be protected the glass fiber precursor in each strand, and certain gummed power is provided when twisted simultaneously.Secondary dipping is carried out in the periphery of gained glass fibre rope yarn behind the twisted, forms outer rubber shoe latex layer, and this has strengthened the intensity of rope yarn to a certain extent greatly, and the strand and the glass fibre monofilament of inside played the certain protection effect.
Production technology of the present invention is simple, products obtained therefrom have prescription rationally, novel structure, bonding tear fracture intensity is higher, tensile property is stronger and make characteristic of simple, its technology advanced person, product has higher bonding strength and stronger tensile property, can be used for the occasion of high-intensity operation.
