Problems solved by technology

[0005] 1. During the edge grinding operation of the display screen, due to the poor elasticity of the existing polishing pad, its bending angle is small, so that the polishing pad cannot be polished to other angles of the corners of the display screen;
[0006] 2. Since the polishing pad usually has a certain thickness, the inner center of the polishing pad cannot be practically applied to the polishing operation, and it is easy to affect the overall elasticity and softness of the white pad

Embodiment 1

[0053] see Figure 1-Figure 3 , an elastic porous polishing white pad for edging a display screen, comprising a core elastic layer 1, a white pad connecting sleeve 2, an embedded groove 3, a frosted white pad 4, a nylon outer ferrule 5 and a nylon ferrule seat 6, the core elastic The upper and lower sides of the layer 1 are respectively provided with a white pad connecting sleeve 2, and the interior of the white pad connecting sleeve 2 is provided with an embedded groove 3, and a frosted white pad 4 is installed in the embedded groove 3, and the frosted white pad 4 is the core polishing part. Nylon outer ferrule 5 is installed on the side of elastic layer 1 and white pad connecting sleeve 2, nylon outer ferrule 5 is installed on the bottom of nylon ferrule seat 6, nylon outer ferrule 5 and nylon ferrule seat 6 are combined, and the core elastic layer 1 It is connected with the white pad connecting sleeve 2 as a whole.

[0054] see Figure 4 , the frosted white pad 4 includes...

Embodiment 2

[0083] The only difference between this embodiment and the first embodiment is that the material ratio of the styrene thermoplastic elastomer and the polyester thermoplastic elastomer in the raw materials used for the core elastic layer 1 and the white pad connecting sleeve 2 is different. The weight fraction ratio of the raw materials used for layer 1 and white pad connecting cover 2 is as follows:

[0084] 80 parts of styrene thermoplastic elastomer;

[0085] 40 parts of polyester thermoplastic elastomer;

[0086] 2 parts of antioxidant;

[0087] 6 parts of wear-resistant additives;

[0088] 22 parts of nanofillers;

[0089] The weight ratio between the styrene-based thermoplastic elastomer and the polyester-based thermoplastic elastomer is changed to 2:1, that is, the styrene-based thermoplastic elastomer is used as the preparation main body, and the polyester-based thermoplastic elastomer is used as the filler.

Embodiment 3

[0091] The difference between this embodiment and the first embodiment is only that the proportions of the components by weight of the raw materials used for the high elasticity layer 41 and the polishing surface layer 43 are different. The proportions of copies are as follows:

[0092] 30 parts of styrene-butadiene rubber;

[0093] 15 parts of polyurethane elastic fiber;

[0094] 2 parts of triethanolamine;

[0095] 2 parts of triethylenediamine;

[0096] 2 parts of magnesium oxide;

[0097] 3 auxiliary preparations;

[0098] The proportion of polyurethane elastic fibers in styrene-butadiene rubber and polyurethane elastic fibers is increased, thereby reducing the overall elasticity of the high elastic layer 41 and the polishing surface layer 43 prepared as a whole, and improving their overall softness.

Abstract

The invention discloses an elastic porous polishing white pad for display screen edging and a production process of the elastic porous polishing white pad for display screen edging, the elastic porous polishing white pad comprises a core elastic layer, a white pad connecting sleeve, an embedded groove, a frosted white pad, a nylon outer clamping sleeve and a nylon clamping sleeve seat, the frosted white pad is mainly used for improving the overall elasticity and softness of the white pad and saving materials needed for processing the white pad, the frosted white pad part is mainly divided into a high-elasticity layer, a transition filler layer, a polishing surface layer and a frosted surface layer, the transition filler layer is made of nitrile rubber, acrylonitrile, polyurethane and silica gel which are high in elasticity as main materials, and the transition filler layer is made of silica gel. The upper side and the lower side of the transition filler layer are respectively coated with the high-elasticity layer and the polishing surface layer which take the butadiene styrene rubber and the polyurethane elastic fibers as main materials, and the frosted surface layer is pressed above the polishing surface layer, so that the elasticity and the softness are improved while the grinding and polishing capabilities are ensured.

Description

technical field [0001] The invention relates to the technical field of white pads, in particular to an elastic porous polishing white pad for edge polishing of a display screen and a production process thereof. Background technique [0002] White pads are mostly used for polishing, and are usually composed of composite materials. The white pad includes a polishing pad, an adhesive layer and a support layer. The adhesive layer is uniformly coated on the upper surface of the support layer, and the polishing pad covers the adhesive layer. The polishing pad, the adhesive layer and the support layer are superimposed and fixed, and then a punching device is used to open an elastic microporous structure on the white pad. [0003] Patent No. CN202010568253.4 provides a polishing pad material and polishing pad, using polyols containing hydrophobic groups, not only can use the hydrophobic function of polyols to improve the hydrophobicity of the polishing pad material, making the polis...
