Bureau of the Central Government: s: Du Xiaoyin 52. V. Description of the invention () The present invention relates to a novel and substantial closed cell scented thermoplastic foam patella and the preparation of such scented thermoplastic Foaming method. At present, thermoplastic foams have many uses, for example, as packaging buffer M, furniture furniture M and insulation thermoplastic foam (referred to as "foam" in this specification) generally thermoplastic resin and other additives, such as room The size control agent, etc. is passed into the pressure device, so that the composition is melted into a molten material under heating, and a volatile shaking agent is added to the molten material, and the generated material contains volatile by the mold at the end of the extruder. The hot-melt glue of the sex-blown agent is extruded to the region where the pressure is higher than the pressure in the extruder. The thermoplastic foam can be divided into an open chamber (or hole) and a closed chamber. The present invention relates to a substantially closed chamber thermoplastic foam part C One of the shortcomings of the foam is its odor. This odor will not be quickly dissipated. It can be released together with the foam, and it can still be detected after a period of time / some people will feel this odor Unpleasant: In order to eliminate or overcome the odor of polyurethane foam or other synthetic foams with volatile components released after a period of time, the technician adds λ ... Contains foam rubber Among foams, in certain products, such as Gu pads, it is especially desirable to release fragrance for a long period of time. However, the added spices are often easy to dissipate quickly, so that the main odors to be eliminated in the environment are still dominant. It has been known for some time in the past that materials with highly porous members are soaked in materials that are preferably of a liquid type, so as to slowly evaporate at normal temperature and normal K, thus permeating the adjacent air. In addition, a variety of storage and release devices containing a conformal polymeric carrier have also been proposed in US Patent No. 3,857,932 (please read the precautions to write this page first). Binding-Line-Refer to the paper size to use S National Standard (CNS) T4 specifications (210X297 mm) —3 — 81. 4. 10,000 sheets (H) Λ 6 η 6 V. Description of invention (): 3,975,350, and 4,202,880. Can be soaked in porous materials (please read the back and attention matters # 瑱 write this page) various materials, including: _ products, perfumes, deodorants, killing agents, herbicides, anti-inflammatory and disinfectants. It is also known from the fact that the chemical technique is that the insoluble polymer agent of the thermoplastic part will not move at an effective rate, pass through the substance, encapsulate the surface of this substance, and then enter the soluble part in the solid surrounding environment Generally speaking, it is not a problem of open-chamber foam. However, the behavior of substantially closed-cell foam is more like a non-foamed thermoplastic resin, in which the added fragrance must move at an effective rate through the closed-chamber foam material. , Holding the foam skull, and then into the surrounding environment. With the practically sealed sludge foam, each layer of sludge wall is a new barrier to be penetrated by the included spices. Therefore, adding fragrance to a substantially closed-cell foam will greatly increase the total time required to release fragrance to the surrounding environment. U.S. Patent No. 4,339,550 discloses a variety of hydrophilic polyurethane foam products, which is characterized by a cross-linking polymerization type, non-linear molecular network, this network can use various in-situ methods, will live The material is incorporated into the chamber structure of the hydrophilic polyurethane foam, so that the living material has a controlled release. The Ministry of Economic Affairs, Central Bureau of Labor and Industry, β-Consumer Cooperative Du Printing US Patent No. 4,234,] 73 explains how to overcome the odor of new carpets and foam cushions, the method of which is to impregnate the punk with a long-lasting fragrance, The plow type of this kind of fragrance can be: a fragrance wrapped with _ *, which can be slowly released when using the foam patella; or a slow-release fragrance, because this fragrance is included in the foam This way, it will last for a long time. By adding the perfumed particles to one of the main surfaces of the thin foam K, the paper size is reduced to a national standard (CNS) T4 specification (2 丨 0x297 male dragon) -4-81. 4. 10,000 sheets_ (11) Λ 6 I? 6 209 Office 5. Description of invention () (Please read the precautions before writing this page), so that the flat thin plate type foamed eel liner can be saturated with spices. Heating this forging pad will cause the particles to move into the foamy main snakehead. Applying a true chamber to the opposite surface of the foaming distress will cause the particles to move further into the foam. In addition, the diffused particles such as brushes or wipes can be used to distribute the particles, cross the surface of the foam, and enter the open voids in this surface: Finally, the semi-permeable layer can be connected to the surface of the foam patella, Put 1: of the particles to keep them in position. In this way, a long-lasting, long-lasting aromatic foam product can be obtained. However, these documents do not disclose a hibiscus thermoplastic foam with a substantially closed cell and a method for manufacturing such a foam .. In the present invention, it is surprisingly found that when a substantially closed cell is added When the thermoplastic foam (the foam has a closed chamber of ten percent (70%) or more), a very small amount of perfume can produce a perfume substantially closed-cell thermoplastic foam product. Of spices will not disappear quickly. Employed by the Central Standards Bureau of the Ministry of Economic Affairs to collaborate with Du Printing. In a preferred embodiment, the fragrance is added as a concentrate. Here, the fragrance is concentrated in the polymer resin particles of the thermoplastic parts and is used to make the substance. The thermoplastic polymer resin particles of the closed cell thermoplastic foam product are blended c due to the small amount of polymer in the fragrance / polymer concentrate. Therefore, it is not necessary for the concentrated polymer or perfume to be soluble, or to be able to be mixed with or blended with the polymer resin particles of the thermoplastic used to make the substantially closed-cell thermoplastic foam product; however, ideally it is best So I. This type of foam is pseudo-generally known in this art as a substantially sealed chamber heat-bonded resin foam. 81 · 4, 10,000 sheets (H) The size of this paper is in the middle Η B family tree standard (CNS) T4 specification (2 丨 0x297 public goods) 2〇9 such as Λ 6 ____ Π_6 ____ V.

Volatile blowing agents include conventional blowing agents, such as nitrogen-containing hydrocarbons, etc., for example: 1,2-diazo-tetra-fluoroethane, 1,2-two gas four atmosphere ethane, gas three gas methane, ： 1-Atmosphere-1, i -Difluoroethane, and its mixture with various additives, such as halogenated hydrocarbons, hydrocarbons, digasification sulfonate, water, etc. To be ideal as a blowing agent with an ene polymer, Weng is described in the combination of isobutane and isopropane in U.S. Patent No. 4,96 4,027. If necessary, additives such as core agent, extrusion rib agent, anti-gas agent, coloring agent, rhyme material, etc. can be included in the blend. C. For the purpose of the definition in this specification, the term substantially enclosed chamber means At least 70% or more of the chambers are closed in a single sheet, or in each single-stranded strand bundle in combination with foam, ideally at least 80% or more of the chambers are closed . In the most ideal condition T, at least 90% or more of the chambers are closed. A common method for measuring the content of rigid honeycomb-shaped plastic_open chambers, Tong uses an air pycnometer. ASTM D285ft-87 (American Society for Testing and Materials, Philadelphia, Pennsylvania, United States) provides details of a common test procedure used to determine porosity. This test method is based on the determination of porosity. Among them, the honeycomb plastic's accessible honeycomb volume is determined by the use of wave-ear law, which declares that the reduction of the volume of the enclosed gas leads to A 6 It 6 (Please read the back-to-back precautions to write this page) This paper is used in a country «standard (CN5), specifications (210x297 public address) 81. 4.] 0,000 sheets (H) 209.34 Λ 6 Ιϊ 6 Ministry of Economics # 揮 央 # quasi-bureau Bei Gongxiao $ :: Cooperation Du Yin 31 V. Description of the invention () Proportional increase in pressure c Regarding this test method, a sample of foam with a known external volume is placed in a In a sealed volume of known volume. Move the piston located on the volume area to reduce the volume until the force begins to rise to a percentage of the open chamber as calculated from the amount of foam external volume that does not allow air to flow into the chambers (that is, the foam external volume It is calculated as 100%, and the volume is calculated as 0%). In this specification, it is also used to define the term "r perfume", a pseudo compound, which can be added to the foam for the purpose of generating fragrance (usually no other purpose), and when added to the hair When foaming, a scent associated with the foam can be produced, and this scent can be sensed by the sense of smell of humans or animals. Generally speaking, the ingredients are pleasant or sweet, but this requirement is not an absolute requirement. For example, it may be that certain tastes are known to prevent certain behaviors of certain animals (such as Tsui). This taste may not be pleasant or aromatic to animals or humans: many others The products, such as depolymerization agents, insecticides, insecticides, or disinfectants, can have aromas that are functionally related to this product. However, for the purposes of this specification, the fragrance compound of the product is the focus, not the functionality of the product. In addition, typically, the perfume compound used in the present invention is at such a low level of addition, and therefore, the normal functionality of this product may not be attained by such level of addition. Flavored volatile substances should be in sufficient quantities so that when they are exposed to the selected environment, the desired activity can be granted. Generally speaking, the amount of this volatile material is composed of 〇.〇〇1 to 5% of the total composition of the weight percentage (please read the back to the first note #pot write this page) Installation-Order-- Thread-The size of the clothing paper is based on the Chinese HF standard (CNS) f4 specification (210x297 g; ":") -11- 81. 4. 10,000 sheets (Η) 209 ^ 34 A 6 η 6 Ministry of Economic Affairs Bureau of Central Standards Μ Printed by the work consumer cooperative. V. Description of the invention () It is 0.001 to 1%. Although the active volatile substances may have other uses for the purpose of this specification, however, all the volatile substances used are falsely used for the purpose of fragrance. It is also possible to disperse the scented particles into the foam u ^^ The scented particles scattered in the foam may be fragile containing fragrance. Such thorough capsules are available from several commercial sources and are also described in U.S. Patent Nos. 2,969,330, 3,341,466, 3,341,466, 3,516,943, and 3,415,758, which are incorporated by reference in this document. 0 Due to fragrance release It can be further slowed down and thus extended to a long period of time. Therefore, the use of Che capsules is particularly ideal: when such fragile microcapsules are stressed, heated, or wet, the capsule breaks to release the material. In this type, the release of the fragrance can be extended to an extended period of time: The treatment of the foam during use will break up the gums and release the fragrance. After being used, it may be in the buffer substance And when the initial fragrance is lost, whenever the microcapsules are subjected to pressure, humidity or heat changes, the fragrance will be released. For example, squeezing and buffering foaming alone will cause fragrance release when the pressure is broken and the capsule is withdrawn. The composition and thickness of the microcapsule coating can be adjusted based on expected factors such as maximum temperature and pressure to provide the desired fragrance release. 9 In one option, such scented particles may contain spice-treated bone material, clay, or charcoal. Of course, such particles will not exhibit the extended fragrance release characteristics of withdrawing capsules: however, their use does produce a foam product. The fragrance release time of this product is essentially 1: longer than the manufacturing (please read the back first Zhi Note # 塥 写 此 页) Binding-Bookbinding-Thread < Chinese Paper Standards (CNS) Grade 4 (210X297 Male Dragon) for each paper size, 81. 4. 10,000 sheets (Η) 209-34 Λ fi Π 6 V. Description of the invention () The release time of the fragrance presented by the foam directly added to the fragrance during the cooperation between the employees of the Bureau of Standards and Statistics of the Ministry of Economic Affairs. The delayed absorption of pseudo-bone materials, clay and charcoal and other materials has been added to these carriers. The fragrance will be slowly released into the surrounding environment, and a time delay effect will occur during the release. The scented particles are generally 200 mesh or finer to assist dispersion into the foam composition matrix by the hopper. Experiments on possible carriers of perfumes showed that American Active White, Western Bentonite, and Southern Bentonite are the best carriers. The fragrance can be distributed to the foam by adding the capsules containing fragrance, or the particles loaded with fragrance, or the fragrance itself to the unused batch or reprocessed batch. However, if the capsules are removed and added during the foaming process, most of the capsules will be broken due to the heat and pressure generated during the treatment. Therefore, δ releases many spices. By using any type of particles, including Qulu II, it will lead to two shortcomings: the immediate release of spices, which is pseudo-unfavorable; 2) these particles may cause the formation of crystal nuclei in the foam chamber, thus causing foam engraving The problem: if it is not possible to produce a substantially closed-cell foam by using particles, at this time, the fragrance will be used directly, or the fragrance will be incorporated into the foam in a concentrated form. The aforementioned U.S. Patent No. 4,694,027 (incorporated herein by reference) in this specification pretends to be wider than the Chong procedure to prepare a substantially closed-cell olefin polymer foam with dimensional stability. Also incorporated herein by reference is U.S. Patent No. 4,824,720, which discloses a method for manufacturing a closed cell foam, which is particularly suitable for packaging applications and contains a plurality of knots composed of a foamed thermoplastic Strand or shape.

Subsequently, an extruder or any other suitable device is used to incorporate a conventional volatile blowing agent and any additives. Next, the extrudate is preferably forced through a mold plate in a vibratory manner. The plastic template contains multiple small holes, which are located in a space configuration suitable for the needs, or in an array of slots, and the vibration type can be sine wave, honeycomb, square wave sawtooth or triangular sawtooth wave.:, On the other hand In the use of holes in the molding panel, different geometric shapes, especially non-circular shapes, such as X-shaped, cross-shaped, or Li-shaped can be used.
