Abstract
The invention belongs to toughener fields, and in particular to a kind of polyolefine toughener is grouped as by the group of following parts by weight: 40-50 parts of EP rubbers, 25-35 parts of pentaerythrite, 20-35 parts of pentaerythritol stearate, 2-6 parts of antiaging agent；The antiaging agent is the compound of ultraviolet absorber, antioxidant, and the mass ratio of the ultraviolet absorber and antioxidant is 1:1-1.2.Using the beneficial effects of the present invention are: the polyolefine toughener toxic side effect is small, low temperature resistant heat-resist, good impact resistance.
Description
Technical field
The invention belongs to toughener fields, and in particular to a kind of polyolefine toughener.
Background technique
Toughener, which refers to, can increase the flexible substance of adhesive film layer, and plastics are very widely used since invention,
The toughness of plastics is always people's concern, and toughener is to reduce the brittleness after plastic hardening and improve its impact strength
A kind of additive being added with elongation percentage.Toughener can be divided into rubber toughener and thermoplastic elastomer (TPE) class toughener, increase
Tough dose of general all active group, can chemically react with resin, not exclusively compatible after solidification, also want split-phase sometimes, can obtain
Comparatively ideal toughening effect is obtained, keeps heat distortion temperature constant or decline is little, common toughener is polyethylene toughener, two at present
Sad toughener, still, polyethylene toughener increase opacity, and low-temperature resistance effect is bad；Two sad toughener poison are secondary to be made
With big therefore big to human injury in process, and the toughening efficiency of the prior art is low, and poor impact toughness is easily torn.
Summary of the invention
The technical problem to be solved by the present invention is to overcome toughener toxic side effect in the prior art is big, shock resistance difference
Technical deficiency provides a kind of polyolefine toughener environmentally friendly, toughness is good.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of polyolefine toughener, composition is by weight ratio are as follows: and 40-50 parts of EP rubbers, pentaerythrite 25-35
Part, 20-35 parts of pentaerythritol stearate, 2-6 parts of antiaging agent.
Further, the antiaging agent is the compound of ultraviolet absorber, antioxidant, the ultraviolet absorber and antioxygen
The mass ratio of agent is 1:1-1.2.
Further, the ultraviolet absorber is selected from: phenyl salicylate, group-substituted acrylonitrile, triazines and ultraviolet light are inhaled
Receive at least one of agent UV-P.
Further, the antioxidant is selected from: at least one of antioxidant 1010, anti-oxidant DLTP and antioxidant TNP.
Further, a kind of polyolefine toughener, composition is by weight ratio are as follows: and 45 parts of EP rubbers, pentaerythrite
30 parts, 25 parts of pentaerythritol stearate, 4 parts of antiaging agent.
The purpose that the present invention uses EP rubbers is: EP rubbers is with ethylene, propylene for main raw material monomer, using having
Organic metal catalyst, amorphous rubber made of being copolymerized under solution state.The content of usual propylene is about 40-60% or so,
The content of Third monomer is about 2-5%, 250,000 or more average molecular weight, and wider distribution.Due to the third of introducing in EP rubbers
Alkene destroys original polyethylene crystallization with unformed arrangement, thus becomes the irregular noncrystalline rubber of copolymerization, while retaining again
Certain characteristics of polyethylene.EP rubbers is substantially a kind of high-molecular compound of saturation, and intramolecular does not have polarity substitution
Base, chain link are submissiveer.Its ozone resistants, weatherability, resistance to ag(e)ing be in general purpose rubber it is best, electrical insulating property,
Chemical-resistant and impact resistance are all preferable.
Using the beneficial effects of the present invention are: the polyolefine toughener toxic side effect is small, low temperature resistant heat-resist, shock resistance
Property is good.
