• 322519 A7 _ B7 Fifth, the description of the invention (1) Commercial use of the looped city The present invention is related to a dust-free paper, and more particularly the present invention provides a dust-free paper for cleaning rooms, etc., which has excellent stiffness and It is resistant to stacking and is prepared by including a polymer composition containing two different polymer substances to be determined and different glass transition temperatures (Tg) in the paper. The food industry Η pen Til, the body made by the industry is half as good as the industry. The technique is high in the set up and the room leads to the cleaning of the cleanable things or the dust of the industry. There are many reasons for this reason. The product industry has created a defect and made it into a compact shape or prepared it for the purpose of disability (please read the precautions on the back before filling out this page). Use or write the book room of Eneshu B. For this or for paper, record the source of a note. The dirt and dust of the ring species prepared in the environment should be cleaned and dried. The paper should be equal to the heat resistance of the paper and the paper pulp. The paper should be brushed and printed. It should be expensive and expensive. C Compare paper. The fat tree is made into a kind of pan-and-complex species, which is not produced here. The poor polymer phases of ene, benzene, and benzene are changed to form sheets * I. It is also comprehensive and successful. The resistance of the pulp paper to slack and fibrous properties is improved by the use of agents. It is overheated. Good health. The Ministry of Economy ’s Central Standards Bureau employees ’consumption cooperation. As shown in the example, there is a case of pseudo-clear hair, 〇Immersed gum containing acid lactene or polyacrylic acid liquid polycondensation polymer from which it is formed into a p-shaped form of 10 substances in the compound is not a common degree of warm type The film should be made of chlorine and used in small amounts.

Description of Invention (2) Japanese Patent Publication 1 〇5 1 9 9 / 8 8 shows a method of preparing dust-free paper, so that hollow pigments are impregnated or coated in paper together with synthetic resins having a glass transition temperature not higher than Ot: such as polyacrylate, polyvinyl acetate or polyethylene or latex . Also, Japanese Patent Laid-Open Publication 1 6 7 996/7 5 shows a dust-free paper prepared by adding a polymer substance having a glass transition temperature not higher than 0¾ to paper. Examples of such polymeric substances are acrylic terpolymers, emulsions of acrylate polymers and vinyl acetate / acrylic acid copolymers, which are saturated in paper by dipping. It proves that the amount of dust generated by the paper decreases as the glass transition temperature decreases, and the amount of dust formed is extremely small when the Tg is -50 t: Too invented to solve the twilight night, however, the problem is really like T. Therefore, although the paper made from hungry pulp contains a polymer substance with a glass transition temperature of -40T: to -50 T: at a low glass transition temperature, the amount of dust generated is extremely small, but this paper has appeared Poultry's overlapping nature and lower stiffness. Moreover, in the S-side, when the glass transition temperature is from 0Γ to -2〇υ, although the paper can show stiffness, the amount of dust formed has not decreased. Therefore, a dust-free paper with both properties is needed, that is, a dust-free paper with stiffness and resistance to stacking. The present invention provides a composition for dust-free paper, including a polymer composition, which contains a polymer substance having a glass transition temperature (Tg) in the range of -20 l to 7010 and having a glass transition The temperature (Tg) is in the range of-65¾ to lOt: polymer materials, of which the glass transition temperature difference between the two types of polymer materials is 30 (please read the precautions on the back before filling this page) This paper scale is applicable to the Chinese national standard falcon ( CNS) Α4 specification (210 × 297 mm) 4 9 1309 Attachment _ 322519 A7 B7 Ά Printed by the Consumer Standardization Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V.

The dust-free paper with excellent paper stiffness and anti-overlap property can be obtained by using the composition for dust-free paper of the present invention. Any natural polymer and synthetic polymer can be used as the polymer substance of the present invention. Examples of natural polymers are natural rubber, and examples of synthetic polymer materials are synthetic rubbers composed of unsaturated monomers such as ethylene, propylene, gas ethylene, vinyl acetate, styrene, acrylonitrile, methacrylonitrile, acrylic acid Ester, methacrylate, acrylic acid, or methacrylic acid; and polymers or copolymers obtained by polymerizing diene monomers such as butadiene or isoprene.

Invention Instructions (4) The surrounding polymer substance is a hard component and has a glass transition temperature (Tg) at- The polymer material in the range of 65 TC to 10Ό is a soft component. The preferred range of Tg for hard components is-IOC to 50Ό, to 〇υ to 40Ϊ: better. Furthermore, the preferred range of Tg for soft components is -551C to -lOt: , The range from -55 10 to -35 < 0 is better. The glass transition temperature of the hard component is higher than the glass transition temperature of the soft component by more than 30 ° C, preferably higher than 50 ΊΠ, and the difference of more than 7010 is better. In the invention, several kinds of polymers can be used as the hard component and the soft component, as long as each of them can meet the above requirements. In the composition of the present invention, the average glass transition temperature (tg) of the hard component and the soft component is -3010 to 2010 The range is preferably _2〇 To the range of -101C. If the average glass transition temperature is low, the paper does not have stiffness and poor lamination properties. On the other hand, if the average glass transition temperature is too high, it will produce more dust and not good. Polymer glass The transition temperature can be calculated by the following Fox's program [Bulletin of American Physical Society, 13, page 123 (1956)]. L / Tg = Wi / Tg (1) + W2 / Tg (2) Here, Wi and W2 are the weight fractions of component 1 and component 2, and Tg (l) and Tg (2) represent the glass transition temperatures of component 1 homopolymer and component 2 homopolymer (unit: Absolute temperature). In addition, the average glass transition temperature (tg) in the present invention can be calculated from the aforementioned Fox formula using the glass transition temperature (Tg) of the polymer or homopolymer.
