Description

Polypropylene building mould additive and preparation method thereof
Technical field
The invention belongs to chemical material fields, and in particular to polypropylene building mould additive and preparation method thereof.
Background technology
In construction projects, building template is the important tool of concrete structure engineering construction, and accounts for project cost ratio It is larger, directly affect the quality, cost and benefit of engineering construction.As Chinese society economic development and urbanization process are accelerated, Construction scope is increasing, have become the maximum country of construction scope in the world, in recent years polypropylene plastics building template Basic physics characteristic, supported design and superiority in economy, are of great significance for architectural engineering.
Invention content
Goal of the invention:In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide polypropylene building mould additive.
Another object of the present invention is to provide the preparation methods of above-mentioned mold additive.
Technical solution:In order to reach foregoing invention purpose, the present invention is specifically achieved like this:Polypropylene building mould Additive, by DBS auxiliary agents, antioxidant, hydrotalcite and metal soap lubricant are compound obtained.
Specifically, including following components in percentage by weight:Primary antioxidant 20 ~ 40%, auxiliary antioxidant 10 ~ 30%, DBS Auxiliary agent 30 ~ 50%, hydrotalcite 10 ~ 30% and metallic soap salt 10 ~ 30%.
Wherein, the primary antioxidant is four [β-(3,5- di-tert-butyl-hydroxy phenyls)Propionic acid] pentaerythritol ester.
Wherein, the auxiliary antioxidant is three [2,4- di-tert-butyl-phenyl] phosphite esters.
Wherein, the DBS auxiliary agents are beta-crystal nucleating agent.
Wherein, the metallic soap salt is magnesium stearate.
Each component is put into high speed mixer by formula ratio and mixed by the method for preparing the polypropylene building mould additive 20 ~ after forty minutes, enter Squeezinggranulator through helical-ribbon type buffer bin or rolling granulating machine is granulated, generates the column of 2 ~ 3mm Grain to get.
Advantageous effect:The present invention has the following advantages compared with traditional technology:
(1)The transparency and surface gloss of pp are improved, and impact strength, tensile strength, mold and heat distortion temperature is made to carry It is high;
(2)So that pp crystallization rates is accelerated, shorten molding cycle, improves the performance of enterprises;
(3)Additive amount is few, and modified effect is apparent, simple for process.
