A polystyrene resin product.

Polystyrene resin is a styrene polymer, also called styrol resin, is produced by bulk polymerization, solution polymerization, suspension polymerization, emulsion polymerization, etc., colorless and transparent, d 1.05-1.07, glass transition temperature 82 ℃, tensile strength 350-560kg / cm ² , because of its low dielectric constant, hygroscopicity, and good thermal fluidity and thermal stability, it is used as a typical thermoplastic resin for various electrical appliances as well as electrical and thermal insulators.

On the other hand, unlike general-purpose plastic properties of mass production and mass consumption, engineering plastic is a technology-intensive material with characteristics of small quantity production of various kinds, and has excellent mechanical properties, heat resistance, insulation, and chemical resistance, and its use is extensive. It is used as a basic material in all fields such as electricity, electronics, automobiles, aerospace, aviation, architecture, medicine and food. According to the trend of technological development of engineering plastics, research is being actively conducted according to the various characteristics of composite engineering plastics and consumers. The direction of the characteristics development shows improvement of moldability, improvement of long-term environmental characteristics, enhancement of functions, Development to meet the demand characteristics of the consumer include molecular weight control, copolymerization type, additives and the like. In particular, many studies have been conducted to improve the desired properties by adding various additives, but research on polystyrene resins using functional materials as additives is very insignificant, and the results have not been satisfactory.

Also, functional materials generally refer to materials having special physical and chemical functions in terms of thermal, electrical, optical, liquid gas separation, magnetic properties, and biological properties. Functional materials are required more importantly.

In other words, structural materials are used as materials to construct objects, but the mechanical products themselves are becoming smaller and lighter, and the use of materials is also decreasing, while the proportion of information and communication is increasing, and the intelligence and elaboration of machines are strong. Attained the required stage, the functional material is important because the speed of technological progress of the functional material is much faster than the structural material.

In addition, functional material is not a concrete object but a concept for creating an environment where all living things on the planet, including mankind, can survive. Therefore, it is very difficult to explain it or substitute it with existing materials. It can be said that it includes a variety of materials and products made from these materials. And at each stage of manufacturing, use and disposal or recycling, starting with resources and raw materials, these materials and products will not only cause damage to the environment, but also will be able to more actively provide harmony and comfort with the environment. it means.

As a functional material, it is known that a mineral material having a specific gravity of 1.2 or less and exhibiting a wave almost the same as the wavelength generated in the human body can be used as a substitute for various structural materials as well as being effective in the human body. Although it is used to extract from minerals, the amount of extraction from minerals is very small and expensive, and the expected effect is not expressed through the treatment process.

In addition, the mineral functional material as described above can not be added to more than 10% to the polystyrene resin, which is a kind of general-purpose plastics used up to now, it functions as an additive, but it is difficult to use as a main material, which can be expressed by the functional material. It is a situation that can be expressed only weakly, there is a problem that can not be used as engineering plastics.

Therefore, the object of the present invention is excellent in effect due to the functional material and can be used immediately by pulverizing it is economical and can be manufactured in a simple process, can be mixed with a general-purpose polystyrene resin or used as it is, excellent efficacy It is to provide a method for producing a polystyrene resin can also be used as an engineering plastic having.

The present invention is described in more detail as follows.

Method for producing a polystyrene resin according to the present invention is SiO ₂ 79.76wt%, Al ₂ O ₃ 9.87wt%, Fe ₂ O ₃ 0.21wt%, K ₂ O 3.79wt%, Na ₂ O 2.81wt%, CaO 1.59wt% , Deep granite A powder consisting of 0.86 wt% MgO and 1.11 wt% of other trace components containing germanium 0.5-2 ppm, SiO ₂ 73.41 wt%, Al ₂ O ₃ 14.56 wt%, Fe ₂ O ₃ 1.13 wt%, K Deep granite B powder consisting of ₂ O 4.13 wt%, Na ₂ O 2.48 wt%, CaO 2.28 wt%, MgO 0.72 wt% and other minor components 1.29 wt% containing germanium 0.5-2 ppm, SiO ₂ 73.53 wt%, _{Al 2 O 3 12.52wt%, Fe} 2 O 3 4.76wt%, K 2 O 3.78wt%, Na 2 O 2.07wt%, CaO 1.56wt%, MgO 0.51wt% , and other minor components containing germanium 0.5~2ppm Deep granite C powder composed of 1.27 wt%, SiO ₂ 54.42 wt%, Al ₂ O ₃ 9.16 wt%, Fe ₂ O ₃ 1.87 wt%, K ₂ O 4.18 wt%, Na ₂ O 3.74 wt%, CaO 4.17 wt %, MgO 14.19wt% and other granules 8.27wt% of deep granite D powder, SiO ₂ 79.89wt%, Al ₂ O ₃ 14.92wt%, Fe ₂ O ₃ 0.31wt%, K ₂ O 1.24wt%, Na ₂ O 0.64 wt%, C 15 to 60% by weight of the composition for the functional material comprising at least one deep granite powder selected from the group consisting of deep granite E powder comprising aO 1.89 wt%, MgO 0.17 wt% and other minor components 0.94 wt% It is characterized by mixing 40 to 85% by weight of a known polystyrene resin and compounding at 170 to 215 ° C to produce a chip.

In addition, the polystyrene resin product according to the present invention is characterized in that the polystyrene prepared by the above method is produced by a molding method commonly used in the technical field to which the present invention belongs.

The deep granite used in the present invention is a pure magma in the crust is cooled in the reduced state, each has a unique color, the color is a unique color formed by cooling the high temperature magma of 4000 ℃ or more is used as the far infrared emissivity is 0.90 or more Far-infrared emissivity changes according to the type of granite granite, the mixing method and the mixing ratio, so that polystyrene resins of various characteristics and uses can be obtained. That is, the deep granite A, the deep granite B, the deep granite C, the deep granite D, and the deep granite E may be used alone, or two or more kinds may be mixed and used, respectively. Is used at more than 10wt%.

The deep granite A, the deep granite B, the deep granite C, the deep granite D, and the deep granite E are all prepared in powder form, and the particle size of the powder is 400 mesh or less. When the particle size of the powder is larger than 400 mesh, when the polystyrene resin of the present invention is mixed with the general purpose polystyrene resin, it does not react with the general purpose polystyrene resin and remains in the form of powder, thereby degrading the quality of the polystyrene resin produced. Since the amount of mixing with the general purpose polystyrene resin cannot be increased much, the effect expressed by the composition for the functional material is weak.

In addition, the deep granite A, the deep granite B, the deep granite C, the deep granite D, and the deep granite E are used by heat treatment, respectively, so that they react with general-purpose polystyrene resins, but the reaction mechanism is not known. It is very important to maintain this accurately, and if it is less than each heat treatment condition category, the heat treatment effect is weak, and it does not play a role as a functional material, and there is a disadvantage that it cannot be mixed in a large amount when mixing with a general-purpose polystyrene resin. However, if the heat treatment conditions are exceeded, there is a problem that it is not economical.

In particular, there is a significant difference between the furnace temperature and the actual tempered granite in the heat treatment, so it must be compensated for exactly.

It is preferable to heat the deep granite A, the deep granite B, and the deep granite C for 20 minutes at 580 ° C, and the deep granite D for 30 minutes at 280 ° C, and the deep granite E for 1 hour at 280 ° C. It was.

However, the above heat treatment conditions may be changed according to the conditions of the granular granite powder, the structural material to be mixed, and the like, the larger the size of the deep granite powder, the longer the heat treatment time, the above heat treatment condition is the deep granite powder The particle size is based on the case of 400 mesh.

Meanwhile, the melting temperature of deep granite A is 1420 ° C, the melting temperature of deep granite B is 1180 ° C, the melting temperature of deep granite C is 1280 ° C., and the melting temperature of deep granite D is 1600 ° C. Melting temperature is 1260 ℃.

The amount of the composition for the functional material composed of the deep granite powder is preferably 15 to 60% by weight, and when the amount is less than 15% by weight, there is a disadvantage in that the effect of the composition for the functional material is weak, and the amount is increased. The better the expression of the effect due to the composition for the functional material is preferred, but when used in excess of 60% by weight, the polystyrene resin of the present invention is not produced.

15 to 60% by weight of the composition for functional materials and 40 to 85% by weight of a known polystyrene resin are mixed and compounded at 170 to 215 ° C to prepare the polystyrene resin of the present invention on a chip.

The temperature at the time of compounding is based on the particle size of the deep granite powder is 400 mesh. If the temperature is below 170 ° C, the quality of the polystyrene resin is not improved because the deep granite powder does not react with the general purpose polystyrene resin. It lowered and it was not economical when it exceeded 215 degreeC.

The temperature at the time of compounding (compounding) is based on the case where the amount of the composition for the functional material composed of the deep granite powder is 25% by weight and is changed depending on the amount of the composition for the functional material, but is not particularly limited. As the addition amount is added or subtracted by 1% by weight based on 25% by weight, the temperature during compounding (compounding) is also preferably reduced by 1 ° C.
