Abstract
The invention provides a formula of a waste PVC cable sheath/cellulosine composite board and a manufacturing technique thereof. Waste PVC cable sheath particles, pure PVC powder, a metal soap stabilizing agent, haloflex, methacrylic acid polyesters and a lubricant are mixed in a high mixing machine; a silane coupling agent is hydrolyzed, the hydrolyzed silane coupling agent and the cellulosine are mixed in the high mixing machine, the two groups of raw materials are put in the high mixing machine, the mixed raw materials are added in a twin screw extruding machine to be mixed and extruded, and the crushed wood plastic is pressed and formed in a die so that the composite board is produced. The wood plastic composite board has the advantages of the wood and the plastic, thereby being widely applied in a plurality of fields, such as various aspects of national production such as furniture, building, industry, vehicle and shipping, and package and transportation.
Description
Technical field
The present invention relates to the recovery and the utilization of waste or used plastics, particularly relate to the prescription and the production method of waste and old PVC cable sheath/wood meal composite panel.
Background technology
In current outdoor building materials were produced, the major part that is adopted was the composite floor board of main component for solid wooden floor board or by solid wooden floor board still.Be the limited timber resources of protection China, must the suitable wood substitutes of exploitation.Be a large amount of generations of waste on the other hand, to environment structure sizable threat, as waste or used plastics is exactly " white pollution " to environment, and wherein polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride thermoplasticss such as (PVC) account for more than 80%.It is a resource that can develop greatly; China is a large agricultural country, and crop stalk is very abundant, simultaneously saw not, equal reproducible utilization such as material such as low, branch material.Fully utilizing, rationally use, save utilization and expanding to recycling again is extremely important thing.
The PVC CABLE MATERIALS is exposed in the physical environment as the crust of electric wire throughout the year, and because the chemical property of PVC, its internal structure is also by havoc, if being re-used as the pure material of plastics carries out recycling, its performance can not satisfy production requirement.A kind of method that comparatively generally adopts be with behind waste and old PVC cable sheath granulation again and pure material mix and make cable sheath again.But this employing reclaimed materials is made cable, in insulativity, weathering resistance with can not show a candle to the product made from pure material on work-ing life, and has very big potential safety hazard.
Summary of the invention
Purpose of the present invention is exactly to utilize problem again for what solve the waste PVC CABLE MATERIALS, provide a kind of prescription and method of utilizing the waste PVC CABLE MATERIALS to produce PVC sill plastic composite board, and the additives for plastics that uses nontoxic or low toxicity in manufacturing processed is to reach environmental requirement.
Purpose of the present invention realizes by following proposal:
The prescription of waste and old PVC cable sheath/wood meal composite panel of the present invention, component and mass fraction proportioning are as follows:
