Abstract
The invention provides an olefin blocked copolymer foam material. The foam material comprises raw materials in parts by weight as follows: 100 parts of an olefin blocked copolymer, 5-10 parts of lignocellulose powder, 4-12 parts of a nucleating agent, 2-10 parts of a compatilizer, 2-6 parts of an antioxidant and 3-7 parts of a foaming agent. The olefin blocked copolymer foam material has the benefits that the lignocellulose powder can improve the air permeability, elasticity, compression deformation performance and anti-impact performance of the foam material, a large quantity of recycled wood materials can be used, and the foam material is environment-friendly.
Description
Technical field
The invention belongs to chemical material technical field, especially relate to a kind of olefin block copolymers foam material.
Background technology
Olefin block copolymers (OBCs) be Dow Chemical with catalysis block copolymerization technological development, its segmented copolymer has the molecular chain of the alternating block of hard and soft chain segment formation.Compared with other existing polyolefin elastomers (POE), olefin block copolymers (OBCs) has the advantage of following uniqueness: the balance between flexibility and resistance to elevated temperatures is better; All there is better elastic recovery and compressive set performance at a room temperature and a high temperature; Tc is higher, shortens the process-cycle; Wear resisting property is higher.These advantages make olefin block copolymers (OBCs) can as the extraordinary surrogate of a lot of soft polymer, as styrene block copolymer (SEBS), ethylene vinyl acetate (EVA), Thermoplastic Vulcanizate, flexible polyolefins ethylene-octene copolymer (POE) etc.Effectively can change the performance of OBCs by adding auxiliary agent, expanding its range of application, a kind of olefin block copolymers foam material of environmental protection needs to research and develop further.
Summary of the invention
The object of this invention is to provide a kind of olefin block copolymers foam material, polyolefin plastics, rubber and unsaturated polyester can be widely used in.
Technical scheme of the present invention is: a kind of olefin block copolymers foam material of the present invention, comprises the raw material of following weight part:
Olefin block copolymers 100 parts
Lignocellulose 5-10 part
Nucleator 4-12 part
Compatilizer 2-10 part
Antioxidant 2-6 part
Whipping agent 3-7 part.
Preferably, nucleator be in talcum powder, silicon-dioxide, calcium carbonate, inorganic oxide one or more mixture.
Preferably, described compatilizer is one or more the mixture in cyclic acid anhydride type, carboxylic acid type, oxazoline type, epoxy type.
Preferably, described antioxidant is one or more the mixture in hindered amines, phosphorous acid esters, monothioester class.
Preferably, described whipping agent is at least one in the aliphatic saturated hydrocarbon of nitrogen, carbonic acid gas, a 3-8 carbon atom.
The advantage that the present invention has and positively effect are:
1, the interpolation of described antioxidant, can strengthen the stability in the course of processing.
2, the introducing of described compatilizer makes other additives more tiny and even in middle dispersion of olefin block copolymers.
3, lignocellulose can increase the ventilation property of foam material, elasticity, compression set performance, shock resistance.
