Problems solved by technology

But it has the following disadvantages: the mesh fiber layer hinders the bonding between the resin layers, the physical properties are low, and the separation of the mesh fibers is difficult during regeneration, because the center is hollow and the strength against local concentrated loads and impacts is weak.
According to the various defects and deficiencies of the above-mentioned composite boards recognized and the poor mechanical properties of the composite boards prepared by the existing technology, the present invention has been designed

Embodiment Construction

[0053] The present invention will be described in more detail through specific embodiments of the present invention below. However, these implementations and the like do not limit the present invention.

[0054] Modified asphalt blend compatible with waste automobile tires

[0055] The techniques used to prepare modified asphalt at home and abroad include matrix method, direct input method, mechanical stirring method, colloid milling method and high-speed shearing method. Among them, the colloid milling method and the high-speed shearing method are the most widely used manufacturing methods at home and abroad.

[0056] The invention adopts a homogenizer, a colloid mill and a high-speed shearing method to prepare the blend of waste automobile tires and asphalt. The ground waste car tire powder is used as a compatible asphalt modifier. Under the strong shear action of the homogenizer or colloid mill, the blend of waste automobile tire powder and asphalt, the modifier rubber pow...

Abstract

The invention relates to a halogen-free flame-retardant dynamic vulcanized ternary ethylene-propylene rubber / polypropylene thermoplastic elastomer, which comprises EPT rubber, polypropylene (PP), cross linking agent, non-halogen flame-proof architecture, plasticizing agent and auxiliary agent, wherein the non-halogen flame-proof architecture employs magnesium hydroxide / red phosphorus system, and the halogen-free flame-retardant ternary ethylene-propylene rubber / polypropylene thermoplastic elastomer is obtained through extrusion machine dynamic vulcanization extrusion granulating. The thermoplastic elastomer can be widely applied into the fields of automobile, architecture and cables where halogen-free flame resistance is needed.

Description

technical field [0001] The invention relates to a preparation method of a plastic composite board composition. The method comprises a modified rosin blend, a modified asphalt blend, a toughened and reinforced blend of a thermoplastic and an impact modifier. The blend exhibits improved melting into an intimate blend during transition of the blended starting components to the blend. Background technique [0002] Known techniques and processes for manufacturing composite panels are: by hot-melt adhesive wood-based panel technology and / or plastic composite panel technology and / or thermosetting resin composite panel technology, for example: by calendering and / or compression molding and / or molding technology finished product. For example: Chinese Patent Publication No. 90103063.5, No. 98122121.1 and No. 8710200. [0003] Composite panels prepared by the methods described above typically include at least one thermoplastic and / or thermoset material. In particular, filling with s...
