Glass fiber chopped strand mat, composite board and preparation method
The invention provides a glass fiber chopped strand mat, a composite board and a preparation method. The glass fiber chopped strand mat comprises glass fiber chopped strands and a thermoplastic binding agent. Wherein the glass fiber chopped strands are bonded through a thermoplastic binding agent, and the mass of the thermoplastic binding agent accounts for 20%-70% of the mass of the glass fiber chopped strand mat. The thermoplastic binding agent is adopted as the binding agent, the mass ratio is large, the flatness and smoothness of the surface of the glass fiber chopped strand mat can be improved, the thermoplastic binding agent is good in flowability and can be directly used for mold pressing to form the composite board, no other binding agent needs to be added, and energy conservation and environment protection are achieved. In addition, the thermoplastic binding agent can be recycled, and the prepared glass fiber chopped strand mat has certain environmental protection significance.
本发明提供了一种玻璃纤维短切毡、复合板材及制备方法，该玻璃纤维短切毡包括玻璃纤维短切原丝和热塑性结合剂。其中，玻璃纤维短切原丝经热塑性结合剂粘结，且热塑性结合剂的质量占玻璃纤维短切毡质量的20％～70％。本发明通过采用热塑性结合剂作为粘结剂，且质量占比较大，有利于提高玻璃纤维短切毡表面的平整度和光洁度，又因该热塑性结合剂流动性好，因此可直接用于模压而形成复合板材，无需再添加其他任何粘结剂，做到了节能环保。除此之外，热塑性结合剂可回收使用，制得的玻璃纤维短切毡具有一定的环保意义。
