[Affect the world's patent] tape
It is often said that the need is the mother of invention. This sentence is certainly good, but the problem is this, "need" is often not their own "out", and always rely on the inventor sensitive and savvy "pull" out, through its ingenious ideas and tough efforts Forming an invention. And the average consumer is always after the advent of the invention to realize that it is the production, life necessities, which led to a strong consumer demand for society. So, invention and creation can lead to new social needs. In the 1920s, American Richard Drew invented transparent tape, the product quickly opened the market, to the world; people continue to improve, the introduction of different functions of the tape, so that the development of Soon the industry.
Richard Drew was born in 1886 and died in 1956. He entered the Minnersota Mining and Manufacting Company in Sao Paulo, Minnesota, in 1923 (later known as 3M). At that time, the company was a small company that created sandpaper. On one occasion, Drew engaged in a new sandpaper, in order to understand the trial performance of the sandpaper, visited the use of the sandpaper car repair shop. He heard the employees of the auto repair shop talking about the problems encountered in dealing with the boundary when dealing with cars in two colors. When a paint is good, to another color of the paint, always with a heavy cover to block the already painted part of the paint, and then on another color paint, but in the removal of the mask, Often the paint off, Drew had produced an idea, if the sandpaper abrasive removed, and in the backboard coated with a suitable adhesive can be formed and light and easy to use the shelter Band, can not solve this problem? He returned to the company, it actively engaged in the development work, from the backplane base paper selection processing, adhesive formulations to the processing process repeatedly selected test, developed with a very light, pressure sensitive plastic 5 cm wide yellow paper With the mask, while the United States and British patent applications.
Drew made a US patent application on May 28, 1928 and obtained U.S. Patent No. US 1760820 on May 27, 1930; the British Patent No. GB312610 was obtained.
The name of the patent is "tape". The invention relates to pressure sensitive adhesives, gum compositions, gum coatings, tapes, and watertight and self-adhesive tapes and coatings. A plurality of new articles are provided on one surface thereof with a pressure-sensitive wrinkled or napped paper adhesive sheet; a removable tape having a pressure-sensitive adhesive coated with a rugged rough paper backing plate and one surface thereof; A film and tape having a surface-coated pressure-sensitive adhesive and another surface coated with a homogeneous fibrous backing sheet with a non-adhesive adhesive; a water-insoluble sensitive adhesive is applied to one surface thereof and the other side is coated with a non-adhesive Homogeneous fiber back sheet of film and tape; these tapes can also be made of tape. The base paper, the back plate refers to kraft paper, cotton cloth, imitation parchment paper, sulfuric acid paper, etc., and after containing dry glue, light yellow glycerin soaking, squeezing, drying, making them soft and tough, easy to break The The adhesive is mainly made of rubber and is mixed with a reinforcing agent synthetic resin, and may be colored with a colorant such as zinc oxide.

(10) which is soaked with gelatin and is coated on one side thereof with a non-drying, pressure-sensitive adhesive tape face (11), a masking tape (12) serving as a paint maker, 13) is adhered to the pressure-sensitive adhesive tape face (11) and forms a protruding portion (14) of the pressure-sensitive adhesive tape surface with the pressure-sensitive tape, and the protruding portion is set at a constant width so that the paint- Close to the desired place.
Began to make the pressure-sensitive adhesive is not so successful, because only the edge of the tape coated with adhesive, the middle did not coat, get the car repair shop to use, the adhesive soon fell down, the painter against Drew said loudly, "Take this back to your Scotch boss and tell him to apply some adhesive on it." Of course, Scotch (Scotland) does not mean a person or place, but a slang Mean the mean of stingy. Drew made a corresponding improvement in the tape. During the same period, he investigated the improvement of the waterproofing and moisture-proof sealant on the tape, making it suitable for use in train refrigerated compartments. DuPont has developed a cellophane, this paper although waterproof, but there are thermal and adhesive coating is not on the issue, Drew on cellophane processing, improved adhesives, the successful development of a transparent tape, that When a lot of food packaging companies asked him to provide plastic food bags with waterproof sealant. Developed by the good times, DuPont launched a heat sealing plastic bag pocket device, 3M company will be with a pressure-sensitive sealant into the store into the store directly to consumers, reversing the decline. Plus just met the world economic depression, people living relatively poor, many users found that transparent tape can be used to make up clothes and broken eggs and so on. What brand of product it? Drew still remember that people began to laugh at him "Scotch", then named Scotch? Tape. Some years later, John Borden, a sales manager for the company, invented a series of different adhesive formulations.
Drew's invention also created a 3M company. In the 1940s, 3M formed the Scotch series. 3M decided to shift from sandpaper, abrasive to sealants, adhesives and tape production, the company more and more varieties of products, by consumers welcome, in short supply, and even won the outage apology advertising. In the 1970s, the company received a US patent (patent number US3691140) for Post-it notes. 3M company recognized as the world's first tape industry brand. 3M has become the world's leading diversified multinational companies, in the global production and sales of tens of thousands of products. Products related to industrial, chemical, electronics, electrical, communications, transportation, automotive, aviation, medical, construction, cultural and educational, office, commercial and household consumer goods. 3M's share price is one of the Dow Jones industrial equity indices.
The main component of the adhesive tape was rubber, and now it is widely used in a variety of polymers. From the base material, there are two-way stretch polypropylene (Bopp) tape, cloth tape, kraft paper tape, the US profile paper tape, fiber tape, PVC tape, PE foam tape, etc .; single-sided tape and double-sided tape; Function, there are warning tape, carpet tape, high temperature tape, stationery tape, anti-static tape, waterproof tape, anti-theft tape, anti-skid tape, shock tape, shading tape, reflective tape, anti-corrosion tape, shielding tape, Bridges, subway, underground concrete joints between the iron composite tape, tape has been used for all walks of life and people's daily life.
