Abstract
The invention discloses alkali-free short-cut precursor fibers for thermoplastic plastics. The alkali-free short-cut precursor fibers are prepared by the steps of performing surface treatment on glass fiber bundles, formed by glass monofilaments subjected to sleeve spinning, by using an impregnating compound, and then cutting off the glass fiber bundles, wherein the impregnating compound contains a caking agent, a lubricant, an antistatic agent and a coupling agent in a mass percentage ratio of (90-110):(5-15):(10-30):(5-40), and preferably in a mass percentage ratio of 100:10:20:5. Therefore, the alkali-free short-cut precursor fibers for the thermoplastic plastics, disclosed by the invention, take water-base epoxy resin as the caking agent, thereby having good protection and bundling properties, and being capable of improving the strength of a product.
Description
Technical field
The present invention relates to a kind of chopped strand, particularly relate to a kind of thermoplastics alkali-free chopped strand.
Background technology
The characteristic of the excellences such as alkali free glass fibre has heatproof, corrosion-resistant, tensile strength is high, specific elongation rate is little, electrical insulating property is good, industrially be widely used, but the temperature tolerance of alkali free glass fibre has its limitation, more than 400 DEG C, loss of strength is very large, limits the application of alkali free glass fibre fabric in high temperature, fire prevention, the field such as fire-retardant.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of thermoplastics alkali-free chopped strand.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of thermoplastics alkali-free chopped strand, comprising: use treating compound to carry out surface treatment to the glass fiber bundle that the glass monofilament spinned through sleeve is formed, cut off afterwards;
Containing caking agent, lubricant, static inhibitor and coupling agent in described treating compound, in described treating compound, the quality of caking agent, lubricant, static inhibitor and coupling agent divides per-cent to be 90 ~ 110:5 ~ 15:10 ~ 30:5 ~ 40;
In preferred described treating compound, the quality of caking agent, lubricant, static inhibitor and coupling agent divides per-cent to be 100:10:20:5.
In a preferred embodiment of the present invention, described caking agent is water-based epoxy resin.
In a preferred embodiment of the present invention, described coupling agent is silane based coupling agents.
The invention has the beneficial effects as follows: a kind of thermoplastics alkali-free of the present invention chopped strand, this alkali-free chopped strand uses water-based epoxy resin as caking agent, makes this alkali-free chopped strand have good protectiveness and convergency, can improve the intensity of goods.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The embodiment of the present invention comprises: a kind of thermoplastics alkali-free chopped strand, comprising: use treating compound to carry out surface treatment to the glass fiber bundle that the glass monofilament spinned through sleeve is formed, cut off afterwards.
Containing caking agent, lubricant, static inhibitor and coupling agent in described treating compound, in described treating compound, the quality of caking agent, lubricant, static inhibitor and coupling agent divides per-cent to be 90 ~ 110:5 ~ 15:10 ~ 30:5 ~ 40, and in treating compound described in the present embodiment, the quality of caking agent, lubricant, static inhibitor and coupling agent divides per-cent to be 100:10:20:5.
Described caking agent is water-based epoxy resin; water-based epoxy resin has good protectiveness and boundling to alkali-free chopped strand, can glass fibre, coupling agent and be enhanced material tight combine, consistency is good; there is quick impregnability, contribute to the intensity improving goods.
Described coupling agent is silane based coupling agents, silane based coupling agents can improve the bond properties of glass fibre and resin, greatly improve the intensity of glass fibre reinforced composion, electrically, the performance such as water resistant, anti-weather, even if when hygrometric state, it is to the raising of matrix material machinery performance, and effect is also very remarkable.
Compared with prior art, a kind of thermoplastics alkali-free chopped strand of the present invention, this alkali-free chopped strand uses water-based epoxy resin as caking agent, makes this alkali-free chopped strand have good protectiveness and convergency, can improve the intensity of goods.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
