Abstract
The invention discloses a production method for a moisture-proof agent for plants in the mechanical industry. The moisture-proof agent is a granular moisture-proof agent prepared from powdered water-absorbent resin and an assistant used for improving liquid permeability, wherein the powdered water-absorbent resin is irregularly-shaped smashed particles obtained from further surface cross-linking treatment of a cross-linked polymer of methacrylic acid monomers and/or methylacrylate monomers. The production method includes the following specific steps: ethyl alcohol, the water-absorbent resin and the mixed assistant are mixed, and the obtained mixture is illuminated by a light wave within the waveband of 300 nanometers to 400 nanometers while maintaining the flowing status of the mixture, so as to obtain the moisture-proof agent. The granular moisture-proof agent includes large particle-diameter (400 to 500 microns) powdered particles. Therefore, the moisture-proof agent achieves remarkable social and economic benefits.
Description
Technical field
The present invention relates to a kind of production method of mechanical industry factory building non-blushing thinner.
Background technology
Along with the progress of science and technology and the development of economic construction; the problem of energy dilemma has become the matter of utmost importance hindering world's every country Economic development and construction; by the impact of resource; crude oil in China disparities between supply and demand become increasingly conspicuous; from 1993; China becomes net import of oil state, needs every year to spend a large amount of foreign exchange Imported oils and petroleum products.Develop the oil substitutes such as fuel alcohol, take measures to save petroleum resources.In recent years, about these sanitary materials as disposable diaper and sanitary towel, its high functionalization and slimming make progress, so there is the water-absorbing resin amount increasing and use in every a slice sanitary material, and water-absorbing resin is relative to the trend of the quality % of the whole absorbing structure be made up of such as water-absorbing resin and hydrophilic fibre.
Specifically, by reducing the consumption of hydrophilic fibre (it has low bulk density) and increasing the consumption of water-absorbing resin (it has excellent water-absorbent and large bulk density), the ratio of water-absorbing resin in absorbing structure is improved.Thus, achieve the object of sanitary material slimming and do not reduce water regain.
A kind of known method, wherein uses a kind of absorbing polymeric forming hydrogel, and saline flow conductivity (SFC) value of this polymkeric substance is at least about 30 (10-7cm 3sg-1); The receptivity value (PUP) by pressure performance under 0.7psi (5kPa) locking pressure is at least 23 grams/gram; About 10gsm is at least with basis weight;
Known a kind of absorbing structure, its water-absorbent resin concentration is at least 40%; Saline flow conductivity (SFC) value is at least about 30 (10-7cm 3sg-1); The receptivity value by pressure performance (PUP) under 0.7psi (5kPa) locking pressure is at least 23 grams/grams;
As the object lesson of absorbent resin, hydrolysate and its cross-linking products of the hydrolysate of starch-acrylonitrile graft polymkeric substance, the starch-methacrylic acid graftomer of neutralization, the vinyl acetate-acrylate copolymer of saponification, acrylonitrile copolymer or acrylamide copolymer can be enumerated, and the crosslinked methacrylic acid of part neutralization.These absorbent resin all have the structure of internal crosslinking and show as insoluble in water.
A kind of known method, wherein: in absorbing structure, gel layer permeability (GLP) is that the water-absorbing resin of at least 4 (10-7g-1) is used to upper strata, and the water-absorbing resin that the receptivity under loads (AAP) under 50g/cm 2 load is at least 15 (grams/gram) is used to lower floor;
Expect that characteristic that these absorbent resin have comprises the such as with no pressure or necessary suction that absorbs water from medium that adds the high-selenium corn multiplying power of pressure, excellent absorption rate, high-gel strength and be entirely satisfactory.Because water-absorbent is subject to the impact of cross-linking density, therefore they need not show positive correlation each other, as cross-linking density increase cause gel-strength increase but absorb water amount reduce the fact show.Especially, such as absorbency and absorption rate, gel-strength and suction are contradictory relation.Therefore, when water-absorbent besin particles contacts with water, the absorbent resin having obtained the absorbency of raising may be avoided the absorption of uniform water and form the part of itself moiety aggregation, thus causes absorption rate extremely to reduce because water does not spread the whole volume throughout water-absorbent besin particles.
A kind of known method, wherein polycation is incorporated on water-absorbing resin by conjugated link(age); Known a kind of absorbent material, it comprises the mixture of following component: can be formed gel, containing the absorbing particles of the polymkeric substance of water-insoluble and water-swellable; With can with the absorbefacient polymkeric substance of improvement of contained at least one component reaction in urine;
For alleviating this phenomenon and obtaining the object with the absorbent resin of high-selenium corn multiplying power and more gratifying absorption rate, the method for giving the surface of water-absorbent besin particles tensio-active agent or fixed hydrocarbon coating is available.The method improves the dispersiveness of the initial water absorbed really, but does not bring sufficient effect to the absorption rate and suction improving single resin particle.
Summary of the invention
In order to solve the problems of the technologies described above, technical scheme of the present invention:
A kind of production method of mechanical industry factory building non-blushing thinner, non-blushing thinner comprises the resin of Powdered absorption moisture and the particulate state non-blushing thinner of hydraulic permeability rising agent (β), the resin of wherein said Powdered absorption moisture is that the cross-linked polymer of the monomer comprising methacrylic acid and/or its salt is comprised mixing absorbent resin in erose pulverized particles after further surface-crosslinked process, water and mixed aid and do not add the step of water-soluble radical polymerization initiator and ethylenically unsaturated monomer, with the step material with this gained mixture of light-wave irradiation while keeping this mix flow state, wherein said particulate state non-blushing thinner has the high diameter powders shape particle of 400-500 micron.
Because method of the present invention does not use any being considered to light wave activation with the water-soluble radical polymerization initiator causing formation table crosslinked or ethylenically unsaturated monomer, and any heat reactivity surface crosslinking agent, therefore, it is possible to reduce material cost.
About the character of material, because it does not use any surface crosslinking agent, it only can significantly improve the absorbency adding pressure of produced non-blushing thinner, and with no pressure under absorbency without any reduction.
In addition, the formation of incidental aggregate when method of the present invention can suppress to mix absorbent resin and water under mixed aid exists, and make while the flow state keeping mixture by becoming possibility with the homogeneous surface modification of light-wave irradiation gained mixture.
