본 발명은 고분자 물질을 주재로하는 토양수 조절기능을 갖는 고분자 물질을 주재로한 다공체의 제조방법에 관한 것으로 더욱 구체적으로는 열가소성수지 또는 고무에 펄프, 실리카겔, 물흡수제, 열안정제, 가교제를 첨가시켜 일정한 형상으로 성형한 토양수 조절기능을 갖는 고분자 물질을 주재로한 다공체의 제조방법에 관한 것이라 하겠다.The present invention relates to a method for producing a porous body based on a polymer material having a soil water control function mainly based on a polymer material. More specifically, pulp, silica gel, water absorbent, heat stabilizer, and crosslinking agent are added to thermoplastic resin or rubber. The present invention relates to a method for producing a porous body mainly based on a polymer material having a soil water control function formed into a predetermined shape.

토양수의 이동에 있어서 강우나 관개수가 가해져 포장용수량 이상으로 포화되면 중력에 의해 공극을 통하여 하강 이동하는데 이동속도는 물의 점성계수와 장력, 토양의 성질과 구조, 지하수의 영향을 받게되고 소공극이 많은 팽창 격자형 점토는 물의 이동 속도가 느려 보수력은 있지만 공기가 통하지 않아 뿌리가 썩거나뿌리의 활착력이 좋지 않으며 대공극이 많은 사질계 토양에서는 물의 이동속도가 매우 빨라 보수력이 거의 없어 식물이 필요로하는 수분이 부족하게되므로 토양 내에 수분을 항상 조절할 수 있도록하는 기능이 필요하다.When rainfall or irrigation water is applied to the soil water and saturated above the amount of paving water, it moves downward through the void due to gravity.The movement speed is affected by the viscosity of water, tension, soil properties and structure, and groundwater. Many expanded lattice clays are water-retaining because of slow water movement, but the roots are not rotten or rooting is poor due to inadequate air flow, and in sandy soils with large air gaps, the speed of water is very fast. As moisture is deficient, it is necessary to be able to control the moisture in the soil at all times.

종래 이와 같은 문제점을 해결하기 위하여 오래전부터 점토 토양에 사질토를 부토하거나 사질토에 점토를 부토하는 방법이있고, 규조토(지오라이트의 일종)와 같은 타공질의 토양을 첨가하여 토양의 수분 및 공기 등을 조절하므로서 토양의 기능을 향상시켰다.Conventionally, in order to solve such a problem, there has been a method of adding sandy soil to clay soil or clay to sandy soil, and controlling the soil moisture and air by adding a porous soil such as diatomaceous earth (a kind of geolite). Thereby improving the function of the soil.

이와 같은 방법은 장기간에 걸친 토양개량 방법이고 막대한 경비가 소요된다.This method is a long term soil improvement method and requires a great expense.

그 밖에도 단기간에 경제적으로 토양에 수분조절기능을 갖게하는 수단들로서 마치 해면과 같이 폴리에치렌 또는 폴리우레탄수지로 발포시킨 연질의 연속성기포 발포체를 토양에 매설하여 수분 조절기능을 갖게하는 것이 있는가하면 섬유의 집속체를 토양에 매설하여 수분조절기능을 갖도록하는 수단들이 있으나 이들은 지지력이 없어 토양의 압력에 이기지 못하여 원래 형태가 축소되므로서 많은량의 수분을 흡수할 수 없고 또한 모세관이 손상되어 물의 이동을 방해하는 단점들이 있다.In addition, as a means of economically controlling moisture in the soil in a short period of time, soft continuous bubble foams foamed with polyethylene or polyurethane resin, such as sponges, are embedded in the soil to provide moisture control functions. There are means to embed moisture in the soil to control water, but they do not support the soil's pressure due to lack of bearing capacity, so they cannot absorb a large amount of water and damage the capillary tube. There are disadvantages to disturb.

본 발명은 보수력이 약한 토양이나 가뭄이 심한 메마른 토양, 원예작물을 재배하는 비닐하우스 내의 토양, 화분의 흙 등에 메몰시켜 토양에 항상 일정한 수분을 갖게하는 토양수분 조절기능을 갖는 고분자 물질을 주재로한 다공체를 해결함에 있으며 기능적으로는 종래 토양에 수분조절 기능을 갖도록 하는 열가소성수지 연질발포체나 섬유의 집속체와는 달리 지지력이 있어 토양의 내압에 견딜 수 있으면서도 물의 흡수량이 많고 적정수준의 물의 공급으로 항상 토양에 일정한 수분을 갖게하는 고분자 물질을 주재로한 다공체의 제조방법을 해결함에 있다.The present invention is based on a polymer material having a soil moisture control function so as to have a constant moisture in the soil by immersing the soil in weakly conservative or drought severe soil, the soil in the plastic house for growing horticultural crops, the soil of the pollen. Unlike a thermoplastic soft foam or fiber concentrator, which solves the porous body and functionally controls water in the soil, it has a supportive ability to withstand the internal pressure of the soil, while absorbing water and supplying water at a proper level. The present invention addresses a method for producing a porous body mainly based on a polymer material having a constant moisture in soil.

Examples of the hydrophilic polymer include polymers such as CMC and PVA. And glycidyl methacrylate, arylglycidyl ether, and the like. Examples of the heat stabilizer include monoiso citric acid-furophyll, 4,4'-tetramethylaminodiphenylmethane, and the like.
