Abstract
The invention provides a halogen-free environmentally-friendly phenolic moulding plastic and belongs to the technical field of high-polymer materials. The halogen-free environmentally-friendly phenolic moulding plastic is prepared from the following raw materials in parts by weight: 47.5-54.2 parts of phenolic resin, 3-5 parts of flexibilizer, 2.5-5.8 parts of curing agent, 1.2-2.3 parts of curing accelerator, 1.4-2.3 parts of demoulding agent, 5.4-7.8 parts of phosphate, 47-56 parts of filler, 19-26 parts of reinforced fibers, and 0.6-1.1 parts of carbon black. The halogen-free environmentally-friendly phenolic moulding plastic has the characteristics of being good in thermal resistance and flame retardance, high in strength, and environmentally-friendly, and can achieve the bending strength of 90-110MPa, the thermal deformation temperature of 215-228 DEG C, the flame retardance property of UL-94-V-0 level (3mm), and the gap impact strength of 3-4kj/m<2>.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of environmental protection phenolaldehyde moulding compound of Halogen.
Background technology
Resol is by the polycondensation and getting under an acidic catalyst of phenol and formaldehyde, makes the various materials with actual application value by adding other necessary component.Along with taking place frequently of fire, it is found that there are a lot of shortcomings in traditional halogen flame, the smog that discharges during burning diminishes environmental protection and HUMAN HEALTH, and goods discarded after, fire retardant harmful in the goods can diffuse in the environment along with goods, causes environment damage such as water body, soil.Common way is the content that control adds halogen in the material, namely usually with content of halogen control at 900ppm, but facts have proved that this add-on is difficult to show gratifying counterbalance effect fire-retardant between the two with environmental protection.In view of this, be necessary to be explored, so the applicant has done experiment repeatedly, has formed technical scheme described below finally.
Summary of the invention
Task of the present invention is to provide a kind of and helps significantly to improve intensity, be conducive to embody the feature of environmental protection and be of value to the environmental protection phenolaldehyde moulding compound of the Halogen that ensures desirable flame retardant resistance.
Task of the present invention reaches like this, a kind of environmental protection phenolaldehyde moulding compound of Halogen, and its raw material by following parts by weight is formed:
In one embodiment of the present of invention, described resol is the resol that acid system is produced.
In another embodiment of the present invention, described toughner is the nitrile rubber of maleic anhydride graft.
Among another embodiment of the present invention, described solidifying agent is six methylene radical tetramines.
Among another embodiment of the present invention, described curing catalyst is magnesium oxide.
Of the present invention also have among the embodiment, and described releasing agent is calcium stearate.
More of the present invention and among embodiment, described phosphoric acid salt is hypo-aluminum orthophosphate.
Among of the present invention and then embodiment, described filler is activated Calcium carbonate.
Of the present invention again more and among embodiment, described fortifying fibre is lignocellulose.
Among again of the present invention and then embodiment, described carbon black is the oil soluble carbon black.
The environmental protection phenolaldehyde moulding compound of Halogen provided by the invention has that heatproof combustion resistance is good, intensity is high, the characteristics of environmental protection, and after tested: flexural strength 90～110MPa, 215～228 ℃ of heat-drawn wires, flame retardant properties reach UL-94-V-0 level (3mm), notched Izod impact strength 3～4kj/m
