Description
Technical field
The present invention relates to polymer composite and manufacturing method, especially a kind of unsaturated polyester resin foaming composite wood
Material and manufacturing method.
Background technique
Unsaturated polyester resin have moulded manufacturability is good, raw material sources are extensive, it is cheap, solidify after resin mechanics
The advantages that performance is high has become the basis material that composite material is most widely used.But its brittleness is big, solidification when volume contraction
The disadvantages of rate is big is subject to certain restrictions it in the production and use process, although the SMC and BMC that are made into using fiber reinforcement
Composite material is pressed into various products, solves the disadvantages of brittleness is big, shrinking percentage is big, but also deposits the big (1.8~2.0g/ of density
cm3) the shortcomings that, do not meet current lightweight power conservation requirement.
The unsaturated polyester resin foamed material of existing research at present, although by unsaturated polyester resin low-density lightweight
The product for pushing away further, but obtaining, mechanical property is low, without practical application value, limits the application range of product.
Summary of the invention
Goal of the invention: in view of the above-mentioned problems, an object of the present invention is to provide a kind of environmentally friendly, light, fire-retardant insatiable hunger
With polyester resin foamed composite material, the second object of the present invention is to provide its manufacturing method.
