Abstract
The present invention relates to and utilize the adding stabilizing agent in the process modification to the water proof type nonwoven fabric, particularly the present invention, the means of catalyst are formulated to adhesive and have made the powerful nonwoven fabric of excellent properties water proof type with waterproofing agent.The main component of its waterproofing agent comprises polyvinyl alcohol, bonding agent, and stabilizing agent, the synthetic fiber waterproofing agent, catalyst adopts certain process sequence formulated.Utilize this kind water proof type strong binding glue, can form the packaging bag of high-quality waterproof cement, thereby this product and technology there are great function at cement package bags especially to changing the new replacement of changing of present packing business.
Description
The invention belongs to the improvement of nonwoven fabric manufacturing technique, a kind of more precisely novel powerful water proof nonwoven cloth and manufacturing technique thereof particularly are used for making the nonwoven fabric of cement package bags.
Nonwoven fabric is used for making packaging bag, and technology is simple, and is with low cost and easily reclaim with the back, so be subjected to the welcome of packing business since it comes out.Comprise in the common producing technology of non-woven fabrics: the impurity elimination carded, the fiber combing, air lay, the rolling moulding is rolled in the dip bonding agent, these basic working procedure of heating, drying and baling.The non-woven fabrics apparatus of producing by above technological process is simple, technical maturity, and water consumption is low pollution-free, and finished product has air permeability and good, folding resistance and crack resistance, and have good printing performance, mantle friction to help moving and rising buttress greatly.Because the single brooming that is difficult for of its fiber of chemical fibre (for example polyvinyl) itself, the combination between the fiber depends on that fully adhesive realizes in this class producing technology of non-woven fabrics.Thereby choose adhesive and then become important technology key in the nonwoven production process.But owing to the single water-soluble binder that is that is adopted in the common process, thereby it is poor to form outstanding weakness-water resistance, and wet strength is too low.The product part is subjected to cracky after the water logging, uses field boundary and closes thereby limited it greatly.Particularly be used for the making cement packaging bag, need nonwoven layer that the better waterproof energy is arranged.For addressing this problem, the present inventor also once applied for the relevant patent of water proof nonwoven cloth production technology.In this application technology is improved.That is: after the bake drying operation, added a waterproof intensive treatment operation again.Add the nonwoven fabric oven dry back dip-coating intensified waterproof agent behind the gum forming, and then roll rolling, form final products through the hot air drier dried.Strengthen greatly through its water resistance of nonwoven fabric after this PROCESS FOR TREATMENT, yet this technology has increased operation, strengthened equipment investment, particularly post processing waterproof operation is influenced by the dried adhesive of pre-treatment, it is not thorough to make waterproofing agent soak into fiber, thereby its water resistance is unsatisfactory, its wet strength then has obvious decline to have influence on the quality of product after particularly being subjected to the water logging of long period, in order further to improve technology, the same industry is being sought a kind of more rational PROCESS FOR TREATMENT always, particularly select a kind of water proof type adhesive, but do not succeed all the time.
The objective of the invention is to, a kind of new technology of strengthened water proof type nonwoven fabric is provided, utilize the water proof type strong adhesive of special preparation, realize that nonwoven fabric is bonding, waterproof, the disposable technological forming of reinforcement handle, thereby simplify the manufacturing technique of water proof type nonwoven fabric, and improve the physical performance index of its product.
Be that raw material is narrated main design of the present invention promptly below with the polyvinyl chemical fibre.
The objective of the invention is will be with the simplified manufacturing process of water proof type nonwoven fabric, WATER REPELLENT TREATMENT and adhesion-molded and be one procedure, thereby its key is in this procedure and will padding the used adhesive of moulding and intensified waterproof agent mixed preparing becomes the water proof type strong adhesive.Netted chemical fibre is rolled over moulding after flooding this mixed adhesive, send into the drying machine dryness finalization then.The disposable bonding and WATER REPELLENT TREATMENT of finishing fiber.Because waterproofing agent is along with bonding and other effective ingredient evenly are diffused in the fiber together, thereby improve its waterproof index greatly.Obviously, key of the present invention is to prepare the waterproof strong adhesive with superperformance.
Prepare such adhesive and have suitable work difficulty because add the effect that waterproofing agent can have influence on adhesive, how the breaking resistance that directly threatens nonwoven fabric selects prescription then for key problem of the present invention.Water proof type adhesive used in the present invention picks up the selection of industrial chemicals and desirable component and the percentage by weight that the water proof type adhesive has been found in nearly thousand experiments finally through number.It is bonding host that the present invention selects polyvinyl alcohol, and it accounts for 2%-4%, is the enhancing bonding agent by force and to the stronger organic bond of polyvinyl effect with addition of cohesiveness in addition, and it accounts for 4%-8%.Select finished product synthetic fiber anti-blushing agent as waterproofing agent, it accounts for 1%-6%.Add the synthetic fiber stabilizing agent of 0.1%-1.2% and the catalyst of 0.4%-1.1 in addition for its two kinds of chemical properties being had produce the relatively stable reagent that acts between mutually than the raw material of big-difference.Surplus in the above component is a water.Promptly constitute the used water proof type strong adhesive of the present invention, the process for preparation of this special type adhesive is: a, add water by component than with polyvinyl alcohol after the water steam heated make even mixing, add simultaneously and put into bonding agent.B, etc. the adhesive mixeding liquid temperature add anti-blushing agent and stabilizing agent when reducing to 40 ℃-45 ℃ successively, c, the back that stirs add catalyst.D, adding excess water are adjusted pH value between 4.5-6.Can tinning use by the powerful mixture of the made water proof type of above process for preparation.
Further specify below in conjunction with embodiment and the objective of the invention is how to realize.
