Problems solved by technology

However, due to the defects in process design of domestic extruders, the glass fiber strength retention rate is very low, only 20%. The German Dornier imported extruder can solve this problem, and the strength retention rate can reach 80%, but the price of this imported extruder is 40 times as much as domestically produced, and the price of each unit is about 350,000 US dollars

Embodiment 1

[0014] Example 1: Presoaking with Type 140-I Sizing Before Expansion

[0015] The continuous glass fiber is first impregnated with 140-I type sizing agent, and then the glass fiber pre-impregnated with sizing agent is coated and wrapped by a special laminating machine. Here, the coated surface of the glass fiber surface has several air holes. It can ensure the realization of subsequent expansion; the pre-soaking effect of Type 140-I sizing is to maximize the tight adhesion of the glass fiber coating, and the adhesion performance of Type 140-I is the best among all glass fiber sizings. good.

[0016] The above-mentioned glass fibers are pre-impregnated with 140-I type sizing agent, coated with a special laminating machine, and then puffed by a domestic puffing machine. The retention rate of strength can reach 80%! Moreover, the soaking performance of this kind of expanded glass fiber can be increased by 20% on the original basis.

Embodiment 2

[0017] Example 2: Ultra-high temperature and ultra-low temperature cycle treatment after coating

[0018] The continuous glass fiber is first pre-impregnated with 140-I type sizing agent, and then the continuous glass fiber pre-impregnated with 140-I type sizing agent is coated and wrapped by a film coating machine to obtain coated glass fiber. Carry out ultra-high temperature and ultra-low temperature cycle; the ultra-high temperature and ultra-low temperature cycle is to rapidly heat the coated glass fiber to 110-220 degrees Celsius and then rapidly cool it to minus 20-10 degrees Celsius, and cycle 3-5 times, and finally send the coated glass fiber into PH1 type glass fiber puffing machine for puffing.

[0019] Na in the glass fiber can be changed by ultra-high temperature and ultra-low temperature circulation of continuous glass fiber or coated glass fiber + and Zn 2+ The distance between the ionic phases enables the glass fiber to effectively increase the strength retent...

[0020] Example 3: Carrying out ultra-high temperature and ultra-low temperature cycle treatment on continuous glass fibers

[0021] Perform ultra-high temperature and ultra-low temperature cycles on continuous glass fibers; the ultra-high temperature and ultra-low temperature cycles are to rapidly heat the coated glass fibers to 110-220 degrees Celsius and then rapidly cool them to minus 20-10 degrees Celsius, and cycle 3-5 times, and then the continuous glass The fiber is pre-impregnated with 140-I type sizing agent, and then the continuous glass fiber pre-impregnated with 140-I type sizing agent is coated and wrapped by a coating machine to obtain coated glass fiber, and finally the coated glass fiber is sent into PH1 type glass fiber puffing machine for puffing.

Abstract

The invention discloses a glass fiber film-coated puffing process applied to clutch face reinforcement materials, which comprises the following process steps: the continuous glass fiber is first impregnated with a 140-I type sizing agent, and then passed through a film-coating machine to 140-I The continuous glass fiber pre-impregnated with type sizing agent is coated and wrapped to obtain coated glass fiber, and finally the coated glass fiber is sent to PH1 type glass fiber puffing machine for puffing. After the continuous glass fiber of this application is pre-soaked and coated with a sizing agent, there are several air holes on the coating surface of the surface layer, which can ensure the realization of subsequent expansion; the pre-soaking effect of the 140-I type sizing agent is to maximize Tight adhesion of glass fiber sizing, Type 140‑I sizing has the best adhesion performance of all glass fiber sizings.

Description

technical field [0001] The invention relates to the field of clutch face preparation, in particular to a glass fiber coating puffing process applied to clutch face reinforcement materials. Background technique [0002] The traditional glass fiber puffing process is to puff the continuous glass fiber through a special puffing machine, so as to achieve the effect of increasing the permeability of the glass fiber resin. However, due to the defects in process design of domestic extruders, the glass fiber strength retention rate is very low, only 20%. The German Dornier imported extruder can solve this problem, and the strength retention rate can reach 80%, but the price of this imported extruder is 40 times the domestic price, each priced at about 350,000 US dollars. Contents of the invention [0003] The problem to be solved by the present invention is to propose an innovative solution for the above-mentioned shortcomings in the prior art, especially a solution that can effe...
