High-rigidity high-bonding-strength nylon reinforcing material and preparation method thereof

A reinforcing material and high-rigidity technology, which is applied in the field of high-rigidity high-bonding strength nylon reinforcing material and its preparation, can solve the problem that the structural strength, chemical resistance and stress cracking resistance of PC fiber-reinforced materials cannot meet the requirements, and cannot be cured with moisture. The problems of insufficient bonding strength of polyurethane hot melt adhesive and insufficient surface adhesion of nylon reinforced materials have achieved the effect of broadening the field of use, increasing impact strength, and improving tensile properties and bending properties.

Problems solved by technology

[0002] Rigid parts such as front shells and frames of mobile phones and tablets on the market, in order to meet the increasingly thin and full-screen requirements of electronic products, the material modulus, structural strength, dimensional stability, toughness, and chemical resistance of the front shells and frames , stress cracking resistance, surface adhesion, etc. have high requirements, and the structural strength, chemical resistance and stress cracking resistance of ordinary PC fiber reinforced materials cannot meet the requirements
Nylon glass fiber reinforced materials can meet the requirements of material modulus, structural strength, dimensional stability, and chemical resistance for the front shell and frame of mobile phones, but the surface adhesion of traditional nylon reinforced materials is insufficient, and the bonding strength with moisture-curing polyurethane hot melt adhesives Not enough to meet increasingly stringent product testing requirements

Embodiment Construction

[0020] Below in conjunction with embodiment, the present invention is further described:

[0021] In the following implementation cases, nylon 612 is selected from PA612 II produced by Dongchen Ruisen; glass fiber is selected from special-shaped glass fiber produced by Jushi Company with the grade of ECS3F-03-568H. Adhesion promoter selects the bisamino functional group modified organosilicon compound of Guangzhou Jianshuang Chemical Co., Ltd., grade JS-7020; Antioxidant selects the grades 1098 and 168 produced by BASF, which are compounded at 1:2; nucleating agent selects Klein CAV102; Lubricant selects Suzhou Xingtaiguang TAF; In order to illustrate the present invention in more detail, the following preparation example is provided, but the scope of the present invention is not limited thereto. A high-rigidity and high-adhesion nylon reinforcing material and a preparation method thereof, the steps are as follows:

[0022] Step 1: Weigh various raw materials according to the...

Abstract

The invention discloses a high-rigidity high-bonding-strength nylon reinforcing material and a preparation method thereof. The high-rigidity high-bonding-strength nylon reinforcing material is prepared from the following components in percentage by weight: 38-59% of PA; 40-60 percent of alkali-free chopped glass fiber; 0.3-1% of an adhesion promoter; and 0.5-1.5% of other auxiliary agents. The high-rigidity high-bonding-strength nylon reinforced material has good mechanical properties and good surface adhesion, and has a wide application prospect in 3C electronic products such as mobile phonesand tablet personal computers.

Description

technical field] [0001] The invention relates to the technical field of polymer materials, a high-rigidity and high-bonding-strength nylon reinforcing material and a preparation method thereof.
