Abstract
The invention discloses a manufacturing method for glass fiber felt with high strength, at least comprising production unit for short-cutting strand felt formed by forming section, applying segment for binder, heating section, winding segment for felt. At first, glass strand is selected to be cut shortly in the forming section; then after short-cutting yarn is subsided in the forming section uniformly, the binder is added to agglutinate the glass fiber into the felt in the applying segment for binder; finally it is sent into the winding segment for felt to press in cold, cut and wind after it is heated in the heating section. The length of said short-cutting yarn is 30-60mm. the bonding process select binder with dion powder or emulsion and silanes infiltration agent of unsaturated polyester. The binder is added by the proportion of 3-6% of glass fiber. The melting temperature is 100-130 degrees. The infiltration agent is added by the proportion of 0.1-0.2% of glass fiber. The heating temperature in heating section is 150-200 degrees. Compared with the prior technology, the manufactured production in the invention is provided with very high tensile breaking strength and good infiltration performance. It can satisfy high demands of client.
Description
Technical field
The present invention relates to a kind of preparation method, be mainly used in the production glass fiber reinforced plastics product with glass fibre manufacturing glass mat.
Background technology
The glass mat characteristics are that resin impregnated is good, and the physical and mechanical property equilibrium is particularly useful for making the glass fiber reinforced plastics product complex-shaped, that surface requirements is high.Be accompanied by structural behaviour and speed production cycle that users wish to optimize goods, the tension failure brute force of product and the permeation rate of resin etc. have all been proposed very high requirement.The preparation method of existing glass mat mostly is the employing glass fiber precursor, applies binding agent, and the drying and shaping cutting is batched and formed.Though the product that processes can be up to state standards aspect mechanical strength and the permeation rate, can not well satisfy the user to high-tenacity, the fast performance requirement of permeation rate.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and a kind of preparation method with the powerful and glass fiber felt with high-intensity that impregnability is good of high tension failure is provided.
The objective of the invention is to finish by following technical solution: it adopts the short-cut original silk silk felt production unit that comprises that at least forming part, the binding agent section of applying, heating part and the felt section of batching constitute, at first choosing glass fiber precursor lacks in forming part and cuts, then with short short yarn cutting uniform settlement in forming part of cutting, entering the binding agent section of applying adding binding agent again makes glass fibre be bonded into felt, after heating part heating, deliver to the crimping segment cutting of colding pressing at last and batch.
The length of described short yarn cutting is 30-60mm, the wetting property of fiber surface is relevant with the degree of scatter of raw yarn, dispersion rate is high more, wetting property is good more, so the raw yarn weak point is cut to above-mentioned length, improve the wetting property of fiber surface, when short yarn cutting length is 50mm, wetting property is remarkable, described adhesion technique is selected the silane type sizing agent of polyester powder or emulsion binder and unsaturated polyester resin for use, binding agent adds in the ratio of glass fibre 3-6%, and melt temperature is 100-130 ℃, and sizing agent adds in the ratio of glass fibre 0.1-0.2%; Described heating part heating-up temperature is 150-200 ℃.
Be added with the surfactant of 0.1-0.2% in the described sizing agent, surfactant is selected fatty alcohol oxirane place compound for use, the interpolation of surfactant, improved the ability of soaking into of binding agent on the one hand, also can reduce simultaneously the tension force of fiberglass surfacing, thereby make felt more firm, improve the tension failure brute force.
The present invention is further optimization and the improvement to prior art, particularly binding agent applies the control and the interpolation of surfactant in sizing agent of stage key parameter, make the properties of product that process promoting significantly aspect tension failure brute force and the permeation rate, have the very strong market competitiveness.
The specific embodiment
Preparation method of the present invention, at first precursor is sent into short-cut original silk silk felt and produced short-and-medium the cutting of forming part of unit, it is 30-60mm that weak point is cut length, with 50mm is best, then with short short yarn cutting of cutting sedimentation uniformly in forming part, after send into binding agent and 0.2% sizing agent that the binding agent section of applying adds 3-6%, binding agent is selected polyester powder or emulsion binder for use, sizing agent is selected the silane type sizing agent that is applicable to unsaturated polyester resin for use, in melt temperature is that short yarn cutting and binding agent are bonded to felt under the 100-130 degree, through the heating part heating, drying, temperature is controlled at the 150-200 degree again, adopts emulsion binder, optimum temperature is 165 degree, the powder adhesive optimum temperature is 190 degree, colds pressing to cut for the section of batching at last and batches, and colds pressing and adopts the interior water-cooled roller of colding pressing, control water temperature on the one hand, can also control simultaneously the depth of parallelism of pressure roller, guarantee that felt face cutting stress is even, cut smooth.
In order further to improve product in the performance aspect tension failure brute force and the permeation rate, can in sizing agent, add an amount of surfactant, surfactant can be selected fatty alcohol oxirane place compound for use, adds in the ratio of 0.1-0.2%.
