Problems solved by technology

However, the second desizing must be burned at a high temperature of 360-380°C for 36-65 hours to remove the residual size, which not only consumes energy but also affects the strength of glass fibers
[0007] In the patent literature, there are several invention patents related to glass fiber yarn sizing, but no cracking aid is added to the composition of the sizing

Embodiment 1

[0057] Take 100 grams of the current raw yarn size according to Table 1, add 1 gram of alumina with a particle size of 10 nm and evenly mix it into a slurry. The desizing loss on ignition (LOI%) and longitudinal and transverse (MD, CD) tensile strength of the glass fiber cloth were evaluated according to the above test methods.

[0058] The test results are shown in Table 1. Calcined at 380°C for 55 hours, the loss on ignition rate was 0.038%, and the MD / CD tensile strength was 21.6 / 13.6kg / cm 2 ; Calcined at 380°C for 42 hours, the loss on ignition rate is 0.047%, and the MD / CD tensile strength is 22.2 / 13.8kg / cm 2 ; Calcined at 350°C for 55 hours, the loss on ignition rate is 0.049%, and the MD / CD tensile strength is 28.4 / 18.4kg / cm 2 .

[0059] The loss on ignition rate of the slurry is all below 0.05%, and the tensile strength after calcination at 350°C for 55 hours is the highest, indicating that the lower the calcination temperature, the higher the tensile strength.

Embodiment 2

[0061] According to Table 1, take 100 grams of the current raw yarn size, add 1 gram of alumina with a particle size of 10 nm and 3 grams of peroxide DCP and evenly mix to form a slurry.

[0062] The test results are shown in Table 1. Calcined at 380°C for 55 hours, the loss on ignition rate of the slurry is 0.035%, and the MD / CD tensile strength is 21.8 / 13.7kg / cm 2 ; Calcined at 380°C for 42 hours, the loss on ignition rate of the slurry is 0.045%, and the MD / CD tensile strength is 22.3 / 13.9kg / cm 2 ; Calcined at 350°C for 55 hours, the loss on ignition rate of the slurry is 0.048%, and the MD / CD tensile strength is 29.3 / 18.6kg / cm 2 .

[0063] The loss on ignition rate of the slurry is all below 0.05%, and the tensile strength after calcination at 350°C for 55 hours is the highest, indicating that the lower the calcination temperature, the higher the tensile strength.

Embodiment 3

[0065] According to Table 1, take 100 grams of the current raw yarn size, add 1 gram of alumina with a particle size of 10 nm and 1 gram of sensitizer NPG and mix evenly to form a slurry.

[0066] The test results are shown in Table 1. Calcined at 380°C for 55 hours, the loss on ignition of the slurry was 0.038%, and the MD / CD tensile strength was 21.7 / 13.6kg / cm 2 ; Calcined at 380°C for 42 hours, the loss on ignition rate of the slurry is 0.047%, and the MD / CD tensile strength is 22.4 / 14.2kg / cm 2 ; Calcined at 350°C for 55 hours, the loss on ignition rate of the slurry is 0.049%, and the MD / CD tensile strength is 28.4 / 18.7kg / cm 2 .

[0067] The loss on ignition rate of the slurry is all below 0.05%, and the tensile strength after calcination at 350°C for 55 hours is the highest, indicating that the lower the calcination temperature, the higher the tensile strength.

Abstract

The invention discloses a cracking auxiliary agent-containing paste composition. The past composition comprises 1.5 to 4.0 weight percent of paste, 1.0 to 3.0 weight percent of oiling agent, 0.2 to 0.5 weight percent of surfactant, 0.1 to 0.5 weight percent of softening agent, and 0.005 to 5.0 weight percent of cracking auxiliary agent. Compared with the formula of conventional glass fiber yarn paste, the cracking auxiliary agent is added into the paste composition, which can improve the desizing efficiency of a glass fiber fabric, reduce a secondary desizing temperature, reduce desizing time and reduce ignition loss and improve the strength of the glass fiber fabric.

Description

technical field [0001] The invention relates to a size composition, in particular to a size composition containing a cracking assistant and suitable for improving the desizing efficiency of glass fibers. Background technique [0002] The manufacturing method of glass fiber yarn is divided into three processes: glass raw material melting, melt spinning and twisting processing. In the melt spinning process, including spinning, sizing and coiling steps, the molten glass paste that has undergone the melting process flows down through the spinneret of the platinum spinning box according to the principle of free fall, and is cooled instantly by spraying mist water. The sizing device impregnates the surface of the glass fiber with conventional glass fiber yarn sizing (hereinafter referred to as sizing), and hundreds of glass fiber single fibers are bundled into strands by the bundler, and then coiled into a glass fiber cake at high speed by the coiler. [0003] The glass fiber yar...
