[0043]A. Tert-butyl peroxy-2-ethylhexanoate, the concentration is 1.0mmol / L;

[0044] B. 2,2-di-(tert-butylperoxy)butane, the concentration is 1.0mmol / L;

[0045] C, vinyltrimethoxysilane, concentration is 1.0mmol / L;

[0046] D, aminopropyltriethoxysilane, concentration is 1.0mmol / L;

[0047] The molar ratio of A:B:C:D is 1:1:1:1;

[0048] The aging time of the assembly solution is 24h;

[0049] The configuration process of the self-assembly solution is as follows: first, weigh tert-butyl peroxy-2-ethylhexanoate...

Embodiment 2

[0061] The size of the alkali-resistant glass fiber to be bonded is 100×50×0.3 (mm), and the resin material to be bonded is polypropylene (PP). Fast bonding is achieved through the following steps:

[0063] First, use pure acetone solvent to ultrasonically wash the alkali-resistant glass fiber and the polypropylene with absolute ethanol for 30 minutes, and then dry them after washing;

[0064] Then, degrease the surface of the alkali-resistant glass fiber with 10% SK-144 alkali solution at 60°C, rinse the surface with clean water and dry it;

[0065] Then use a low-temperature plasma power source to perform corona discharge treatment on the surface of the alkali-resistant glass fiber and the surface of polypropylene for 30s.

[0066] Step 2): On the surface of the alkali-resistant glass fiber and the surface of polypropylene, self-assemble into a polymer nanofilm:

[0067] The solvent of self-assembly solution is dehydrated alcohol: water=90: ...

Embodiment 3

[0085] The size of the alkali-resistant glass fiber to be bonded is 100×50×0.3 (mm), the resin material to be bonded is high-density polyethylene (HDPE), and the fast bonding is achieved by the following steps:

[0086] Step 1): Preprocessing

[0087] First, use pure acetone solvent to clean the alkali-resistant glass fiber and HDPE with absolute ethanol for 25 minutes, and then dry it after washing; Carry out degreasing treatment, rinse the surface with clean water and dry it; then use a low-temperature plasma power source to perform corona discharge treatment on the surface of the alkali-resistant glass fiber and HDPE for 20s.

[0088] Step 2): On the surface of the alkali-resistant glass fiber and the surface of HDPE, self-assemble into a polymer nano-film:

Abstract

The invention discloses a glass fiber surface and resin material bonding method. The glass fiber surface and resin material bonding method comprises the following steps of: firstly forming a high polymer nanometer thin film by self assembly of glass fiber surfaces and resin material surfaces to be bonded, then spraying a mixed solution of an organic peroxide with low density and an auxiliary vulcanizing agent onto the surface of the high polymer nanometer thin film so as to modify and change the surface of the high polymer nanometer thin film, and realizing the high-strength bonding of glass fibers and resin materials by heating and pressurizing. The glass fiber surface and resin material bonding method has the beneficial effects that the adopted self-assembly impregnating method can treat materials and parts which have complicated shapes and can realize the bonding of the glass fibers and resin materials which have complicated shapes; the bonding method belongs to an environment-friendly formula and is simple and convenient to operate; the bonding strength between the glass fibers and the resin materials is high; and the stability is high.

Description

technical field [0001] The invention belongs to the technical field of glass fiber surface modification, and relates to the bonding of the glass fiber surface and a resin material, in particular to a bonding method for an alkali-resistant glass fiber surface and a resin material. Background technique [0002] The new manufacturing industry in the 21st century should be a manufacturing industry with high productivity, high performance and low environmental load (two high and one low). For more than half a century, as a main material surface treatment technology, chromium passivation process has been widely used in different industrial fields, such as automobile, aircraft and shipbuilding industries. However, Cr contained in chromium compounds 6+ Toxicity and carcinogenicity have seriously hindered the continued use of this process. With the strengthening of people's awareness of environmental protection in recent years, it is imperative to develop "green surface treatment t...
