Description

Eco-friendly composition for preparation of an floor mat for saltpan and an floor mat for saltpan made using it}

The present invention relates to a composition for manufacturing an eco-friendly salt farm mat and an eco-friendly salt farm mat manufactured using the same.

In general, sun-dried salt refers to salt made by evaporating seawater in the sun and wind, and the method of manufacturing the solar heat by sequentially moving salt water from salt reservoirs such as reservoirs, evaporation papers, and crystals formed in tidal flats. Evaporation and crystallization of water, such as wind, to produce sun salt. Sea salt is manufactured by literally evaporating and crystallizing sea water in a tidal flat without other chemicals or chemical reactions.It absorbs minerals necessary for the human body by organic matter, plankton, and microorganisms in the tidal flat, and discharges unnecessary components to produce various salt-like salts. It is known to be suitable for various dishes because it contains a good balance of minerals, low saltiness, and no strong taste. As a form of manufacturing sun salt, top soil can be used, where top soil means that tidal flats or crystals that produce sun salt are compacted and hardened, and top sun salt or top salt is drawn by the sea water on top of the top surface to bring sunlight and wind. It refers to the tidal flat sea salt produced by evaporation, and most of the sea salt produced in the past was the top sea salt produced from top soil.

It is very slippery when you touch the function of salt torsion crystals in summer because of the glycerol content that many salt-repelling microorganisms in salt torsion have made to withstand high osmotic pressures. The slippery function of the crystalline paper is to increase the small-molecular-weight substances in the cells in order to withstand the high osmotic pressure of the microbial cells, wherein one of the small-molecular weight substances is a glycerol component. Microorganisms that have produced glycerol components to withstand high osmotic pressures can no longer tolerate when the salt level of the crystalline paper exceeds 40%, and the mineral components in the cells, which are inorganic salts, vomit and die, thereby increasing the mineral content in the salt.

Therefore, the sea salt which crystallizes and deposits on the bottom of the tidal flat has a high mineral content. However, in order to ensure the quality of top plate sun salt, the soil of top plate must be frequently compacted with a roller or the like to keep the crystalline paper in a firm state, and even when collecting salt to collect salt, the crystallized salt is used in one direction using heavy leek. There are disadvantages of heavy labor and time-consuming, such as having to repeat dragging and dragging. Moreover, in terms of production, toppan salt must be continuously maintained in clear weather, and the temperature must be warm, but the amount of harvesting is slow and the amount of harvesting is low due to the influence of the weather, such as the low temperature of the bottom of the top plate itself, so that salt crystallization does not occur quickly. There are disadvantages.

For this reason, top plate salt has recently been implemented in only a few regions, and most regions use shards such as pottery fragments, ceramic tiles, PVC plates, etc. on the crystalline paper, and these days, the excellent whiteness of sediment salts precipitated PVC flooring is the dominant factor due to the increase in livestock. However, PVC sheet is added with a large amount of plasticizer (mainly a phthalate compound) in order to improve elasticity and adhesion, which are believed to disturb the endocrine system or damage genital organs. Therefore, in most countries and Korea in Europe, the food hygiene law and container packaging prohibit the use of DOP (Dioctyl phthalate), a phthalate plasticizer, in the manufacture of food utensils and container packaging according to the standard, and DEHP (Di- 2-ethylhexyl phthalate (DEHP) is prohibited.

In addition, the Food and Drug Administration and the Ministry of Food, Agriculture, Forestry and Fisheries have a total content of phthalate plasticizers in the PVC plate, which is DEHP (Di-2-ethylhexyl) in the material when tested in accordance with Annex 35.C of the safety standards for products subject to autonomous safety verification under the Quality Management and Industrial Products Safety Management Act. The total content of phthalate, DEHP), DBP (Dibutyl phthalate), and BBP (Benzyl butyl phthalate) is regulated to be less than 0.1%. Compared with the sea salt produced on the floor of the PVC floor, the sea salt produced on the mud flat soil contains significantly more minerals and useful organic compounds, but the top plate salt has more hygiene problems, soil powder, etc. during the sun salt production process than the PCV floor. There are several disadvantages such as inflow of foreign substances and a decrease in production, and PCV sheet or squirrel flies have convenience in handling and management, but there are disadvantages in that mineral contents such as useful inorganic salts of tidal flat cannot be introduced into crystallized salt.

The salting flooring material includes plasticizers to manufacture a salting mat made of PVC material, whereby salting salt crystals can be contaminated with environmental hormones when making salting salts, and these environmental pollutants are introduced into tidal flats or seawater to cause environmental pollution, and make earthen earthenware tops It is necessary to develop a new concept of eco-friendly salt farm mat because there are problems such as hygiene problems and inflow of foreign substances such as soil powder when manufacturing sun salt.

It has the advantage of being able to produce large salt.

In addition, since a plasticizer such as phthalate is not used, there is an advantage of providing an eco-friendly salt base mat.

Hereinafter, the present invention will be described in more detail.

The present inventors intend to provide a composition for manufacturing an eco-friendly salt farm mat and an eco-friendly salt farm mat manufactured using the same.

The composition for preparing an eco-friendly salt wart mat according to the present invention includes an olefin-based TPO (Thermoplastic polyolefin) resin; Carbon black; Sunscreen and anti-aging agent mixture; Infrared absorbers; It contains fillers and additives.

Preferably, the composition for preparing the salt base mat is 70 to 80% by weight based on the total amount of the composition, an olefin-based TPO (Thermoplastic polyolefin) resin; Carbon black 10 to 15% by weight; 2.8 to 5% by weight of a mixture of sunscreen and anti-aging agents; 2-5% by weight of infrared absorber; It is composed of 3 to 9.9% by weight of filler and 2 to% by weight of additives.

According to the present invention, preferably, the sunscreen and anti-aging agent mixture is one in which a sunscreen and an anti-aging agent are mixed in a weight ratio of 1:1 to 2:3.

At this time, the sunscreen may be used as long as it is usually used to prepare a salt base mat. For example, cyanamide cyasorb uv531.

The anti-aging agent is any one of adeka1 ao60, BZP-250N (Benzylpiperazine) or DLTDP (Dilauryl-3,3'-thiodipropionate).

According to the present invention, the olefin-based TPO (Thermoplastic polyolefin) resin is 15 to 20 parts by weight of a partially crosslinked TPO resin, 6 to 10 parts by weight of a fully crosslinked TPO resin, 30 to 38 parts by weight of a non-crosslinked TPO resin and 5 to 5 parts of polypropylene resin TPO resin containing 7 parts by weight is used.

The crosslinked TPO resin is a raw material used to increase melt strength and ensure adequate sagging during vacuum forming, and is divided into partial crosslinking and full crosslinking depending on the crosslinking degree. The partially cross-linked TPO has a structure in which a polypropylene chain passes between partially cross-linked rubbers, so that it stretches uniformly during elongation, thereby minimizing product thickness variations after molding. However, peroxide used as a crosslinking agent has a high degree of odor generation, and changes in physical properties due to heat resistance and light resistance are severe.

Partially crosslinked TPO resin used in the present invention has hardness of Shore A 65, melt index (MI) 06 to 12 g/10 min (230°C, 5 Kg), specific gravity 088 to 090, and other raw materials. When mixing, it is desirable to have little change in properties. Partially cross-linked TPO resin among the TPO resins preferably contains 15 to 20 parts by weight, and if it is less than 15 parts by weight, there may be a problem in that calendering workability and moldability are deteriorated due to decrease in strength, and if it exceeds 20 parts by weight, crosslinking There may be a problem that the odor caused by the initiator.

The fully cross-linked TPO resin is used to prevent problems in airbag deployment property or an inferior trimming property after product molding because the elongation at the edge of the TPO sheet is excessively high. The fully crosslinked TPO resin used in the present invention has the same hardness as the partial crosslinking using a hardness of Shore A 65, a melt index (MI) of 20 to 25 g/10 min (230°C, 10 Kg), and a specific gravity of 088 to 090. It is desirable to have workability. The amount of use is preferably 6 to 10 parts by weight, and if the amount is too small, the effect of lowering the elongation rate is insignificant, and if the amount is too large, unmelted components remain on the surface of the sheet in the calendering process, so product surface quality There may be a problem with this falling.

The non-crosslinked TPO resin has a lower melt strength than the cross-linked TPO resin, but has higher properties than a general olefin resin. Since ethylene propylene rubber (EPR) is mainly used and no crosslinking agent is used, there is little change in odor and physical properties, but the thickness change during molding can cause severe bursting and whitening. In the present invention, a non-crosslinked TPO resin having hardness of Shore A 90, melt index (MI) 06 to 08 g/10 min (230°C, 216 Kg), specific gravity of 088 to 090, and elongation of 600 to 700% is used. good. The amount of use is preferably 30 to 38 parts by weight, and if the amount of use is less than 25 parts by weight, there may be a problem of calendering processability and generation of odor, and if it exceeds 38 parts by weight, the product may cure and burst during molding and whitening. . In the case of the existing TPO resin composition, when the crosslinked TPO resin is used in excess, there is a problem of deterioration in moldability due to an increase in hardness of the resin.

The polypropylene resin is for reinforcing the rigidity of the TPO resin, the amount is preferably 5 to 7 parts by weight, if less than 5 parts by weight, it is difficult to expect the effect by the addition of polypropylene-based resin, 7 parts by weight In the case of exceeding, the elasticity of the prepared salt-base mat is reduced, and adhesion to the ground may be reduced.

According to the present invention, the infrared absorber uses an inorganic infrared moisturizer or an organic infrared absorber,

Preferably, the inorganic infrared absorber uses at least one selected from ATO, ITO, AZO and GZO, and the organic infrared absorber is OPTOGEN NIR-760S, OPTOGEN NIR-810, OPTOGEN NIR-830, OPTOGEN NIR-840S, NIR DYE B4360, NIR DYE B4361, NIR DYE C2886, NIR DYE C3051, NIR DYE D4773, NIR DYE D5013, NIR DYE T3204, NIR DYE T3205, NIR DYE T3220, PARAX NIR, G800, PARAX NIR F800, PARAX NIR F800 T-900, PARAX NIR T-910, PARAX NIR T-980 and one or more selected from PARAX NIRT-880 are used.

According to the present invention, when the content of the infrared absorber is less than 2% by weight, the amount of salt production is low. In particular, there is a problem in that salt having a grain size crystal not suitable for commercial distribution is produced, and 5 weight. If it exceeds %, the cost of the salt pan mat is high compared to the amount of salt produced, which may deteriorate economic efficiency.

The infrared absorber increases the heat capacity of the salt pan mat, thereby increasing the production of salt and contributing to the size, shape, and homogeneity of the salt particles to be produced at a level superior to or similar to the salt produced in the salt pan mat made of PVC. .

According to the present invention, the filler uses talc (TALC) or INCROSLIP.

The INCROSLIP is a wear-resistant additive developed by Croda Europe of the United Kingdom, and is a product that combines wear resistance and antioxidant properties, and is an additive that solves problems such as stain, color change, and odor.

According to the present invention, the carbon black can increase the amount of heat absorbed in the atmosphere and increase the productivity of sun salt by reducing the degree of reflecting the absorbed light. If the content of carbon black is less than the above range, it is difficult to expect an increase in solar salt productivity, and when it exceeds the above range, the durability of the salt-base mat may be deteriorated.

According to the present invention, the additive uses a conventional one that can be used to prepare a salt base mat, and a lubricant is used in the present invention. The lubricant is added to impart lubricity by reducing friction and reducing adhesion, and hydrocarbon-based lubricants such as paraffin wax, polyolefin wax, and polypropylene wax; Fatty acid amide type lubricants such as stearamide, oliamide and erucamide; Ester-based lubricants such as butan stearate, glycerol monostearate, glycerin mono oleate, stearyl stearate, and montan wax obtained by reacting montanic acid; Stearic acid-based metal salt lubricants; Fatty acid-based lubricants such as stearic acid and lauryl acid; Alternatively, alcohol-based lubricants such as cetyl alcohol and stearyl alcohol may be used alone or in combination, but are not limited thereto. If the content of the lubricant is less than the above range, it is difficult to expect the effect, and when it exceeds the above range, physical properties of the salt sheet may be deteriorated.

The composition for preparing a salt base mat provided by the present invention disclosed above can manufacture a mat by a conventional processing method, and accordingly can provide an eco-friendly salt base mat suitable for the production of sun salt.

Below. The present invention will be described in more detail with reference to preferred embodiments.
