Embodiment 1

[0035] Medical dental pad base film, each component and its content percentage in this base film are:

[0036]

[0037] The surface of the base film is formed with concavo-convex lines by embossing rollers, so that the surface of the base film has a matte effect.

Embodiment 2

[0039] Medical dental pad base film, each component and its content percentage in this base film are:

[0040]

[0041]The surface of the base film is formed with concave-convex patterns by an embossing roller, so that the surface of the base film has a haze effect.

Embodiment 3

[0043] Medical dental pad base film, the components and their content percentages in the base film are:

[0044]

[0045]

[0046] The surface of the base film is formed with concave-convex patterns by an embossing roller, so that the surface of the base film has a haze effect.

[0047] When the dental pad is finally used, it is necessary to use glue on both sides of the base film to fit the toilet paper. Using glue can easily damage the toilet paper. Therefore, we added a hot adhesive to the base film, so that the finished product factory can remove the glue laminating machine and directly use the hot pressing to synthesize it. machine, one-step production, fast and convenient. The bonding effect of the two additives in the base film of the invention after high temperature is just enough for the composite fastness of the toilet paper, thereby solving the problem of easy delamination of the finished product during use, not only improving the composite quality of the fini...

Abstract

The invention provides a base membrane of a medical dental towel and a preparation method thereof. The base membrane of the medical dental towel comprises the following components in percentage by mass: 40-50% of PE particles 7042, 15-25% of PE particles 1C7A, 6-14% of PE particles 2020H, 15-25% of PE particles 8008, 4-7% of an additive 265 and 2-5% of an additive 78CB. The preparation method of the base membrane of the medical dental towel comprises the following steps: A) purchasing the raw materials; B) inspecting prior to stocking; C) getting ingredients; D) stirring and mixing; E) preparing the membrane and forming the same; F) slitting and rolling; G) inspecting and packaging; and H) putting in storage and removing from storage. The process difficulty is reduced when the base membrane and toilet paper are compounded, no glue needs to be used, and released layers are avoided in follow-up use, so that the quality of the finished product is improved.

Description

technical field [0001] The invention belongs to the technical field of medical composite materials, and relates to a medical dental pad base film and a preparation method thereof. Background technique [0002] At present, due to the continuous improvement of living standards, people pay more and more attention to the protection and prevention of teeth, and the frequency of dental diagnosis and treatment increases. Dental chairs are needed in dental diagnosis and treatment. In order to prevent various diseases from continuously occurring among patients And dissemination, in order to improve the hygiene and safety of dental treatment, dental pads are gradually being widely used. [0003] When the dental pad is finally used, it is necessary to use glue on both sides of the base film to fit the toilet paper. The use of glue is easy to damage the toilet paper. During the production process of conventional products, the equipment and process are unstable, which often leads to the ...
