Embodiment 1

[0039] Example 1: Such as Figure 3~7 As shown, the present invention will be further explained below in conjunction with the drawings. A glass fiber sheet or profile or pipe. The surface of the glass fiber filament 2 is sequentially wrapped with a surface treatment agent 7 and a thermoplastic resin 12-2; the glass fiber filament 2 runs along the plate 17-1 or the profile 17-2 or the pipe 17-3 The length (longitudinal) direction of the glass fiber is arranged, or the glass fiber filaments 2 are arranged along the width (transverse) direction of the plate 17-1, and are arranged uniformly or in multiple bundles in the above longitudinal and transverse cross-sections;

[0040] The surface treatment agent 7 is one of the following: epoxy resin, bismaleimide, thermosetting polyimide, phenolic resin, cyanate ester resin, unsaturated polyester, lubricant, antioxidant, coupling agent , Or two or more of the above resins; the surface treatment agent impregnates the glass fiber filament 2,...

Embodiment 2

[0062] Example 2, such as figure 2 , 3 , 4, 5, 6, 7, and different from Example 1, the surface treatment agent 7 has been coated on the surface of the glass fiber filament 2 by the manufacturer, and the surface treatment agent 7 is one of the following One: epoxy resin, bismaleimide, thermosetting polyimide, phenolic resin, cyanate ester resin, unsaturated polyester, lubricant, antioxidant, coupling agent, or two or more of the above resins; The surface tension of the impregnated glass fiber filament 2 is increased, and the affinity with the thermoplastic resin 12-2 is increased, which improves the bonding strength of the two; the equipment omits the impregnation device, the second heating device 8, and other components and connection relations and implementation Example 1 is the same.

[0063] A forming equipment for producing glass fiber sheets or profiles or pipes. The equipment in turn includes a plurality of glass filament unwinding devices, a first guide roller 3, a plural...

Embodiment 3

[0071] Example 3, such as Figure 1~7 As shown, the difference from Embodiments 1 and 2 is that a glass fiber sheet or profile or pipe forming equipment also includes a saw blade cutting device 18, which can be cut to a fixed length. The other composition and connection relationship are the same as those in the first and second embodiments.

[0072] Preferably, a glass fiber sheet or profile or pipe forming equipment, the heaters of the first heating device 4, the second heating device 8, and the third heating device 11 are infrared or resistance heaters, and the infrared heaters heat The device has fast radiation, strong penetrating power, fast heating and energy saving.

[0073] Preferably, a glass fiber sheet or profile or pipe forming equipment further includes a plurality of guide rollers 13 located on the right side of the third heating device 11, which are effective for the glass fiber filament 2 and the filament or strip film 12-1. Straighten out and guide the role.

Abstract

The invention discloses a glass fiber plate or profile or pipe and a forming device. The surfaces of glass fiber filaments are sequentially wrapped by surface treating agents and thermoplastic resin. The glass fiber filaments are arranged in the length direction of the plate or profile or pipe and are evenly arranged or arranged in multiple bundles in the above section. The forming device sequentially comprises multiple glass filament unreeling devices, a second heating device, multiple film unreeling devices, a forming die, a cooling sizing device and a traction device. Multiple reels A are arranged on first unreeling discs correspondingly for unreeling. A first heating device comprises a first heater used for heating the glass fiber filaments and a first temperature control device. A steeping device comprises a steeping tank, multiple second guide rollers and a fourth temperature control device. A heating wire or strip-shaped film wraps the glass fiber filaments to form a blank through pulling and extruding. The thermoplastic resin and glass fiber are compounded, forming is easy, the device manufacturing cost is reduced, the operation difficulty is lowered, cost is saved, and the production efficiency is increased by 30% or higher.

Description

Technical field [0001] The invention relates to a glass fiber board or profile or pipe and forming equipment. Background technique [0002] Glass fiber mainly plays a bearing role in composite materials. Combining thermoplastics or thermosetting plastics and glass fibers together to improve the strength, impact and other mechanical properties of the material is one of the ways to improve the performance of the material. In order to play the bearing role of glass fiber and increase the binding force with the resin matrix, in the process of manufacturing glass fiber drawing, coating the surface of glass fiber with organic emulsion or solution surface treatment agent can effectively lubricate the surface of glass fiber and promote harmony Combination of resin matrix. Surface treatment agents include lubricants, antioxidants, coupling agents and the like. The coupling agent has the function of forming a chemical bond between the surface of the glass fiber and the resin matrix, impr...
