Abstract

The invention discloses a kind of high oxygen index (OI)s of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material, including gelatinization layer, foaming layer and base fabric, it is connected between the gelatinization layer and base fabric by foaming layer, and the gelatinization layer is Nian Jie with glue layer is passed through between foaming layer and base fabric and foaming layer；Wherein, the gelatinization layer is grouped as by the group of following parts by weight: 37 parts of 100 parts of basic polyvinyl chloride resin, DPHP or 911 plasticizer, 30 parts of phosphate plasticizer, 3 parts of soybean oil, 2 parts of stabilizer, 3-5 parts of colorant, 15 parts of antimony oxide and magnesium hydroxide compound 50-60 parts with aluminium hydroxide；The foaming layer is grouped as by the group of following parts by weight: 37 parts of 100 parts of basic polyvinyl chloride resin, DPHP or 911 plasticizer, 30 parts of phosphate plasticizer；The present invention, plasticising while, improve flame-proof smoke-suppressing, and component is nontoxic and will not injure human body, greatly improve security performance, while being not in viscous wheel phenomenon in mixing process, and oxygen index (OI) can reach 29-30%.

Description

A kind of high oxygen index (OI) of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material
Technical field
The present invention relates to in-car decorations PVC material technical field, the high oxygen index (OI) of specially a kind of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material.
Background technique
Requirement of the in-car decorations PVC material for this fire-retardant block at present is also held in the GB/T8410's for being required to meet early stage Horizontal firing requirement.But as product up-gradation requires, safe reliability is improved, the required standard material of early stage is burning Can generate a large amount of smog in time, while discharging heat, such interior space generates fatal harm to passenger when burning, The oxygen index (OI) of current interior trim PVC material is not achieved 24% or so and just releases new regulation and require oxygen on the basis of fire-retardant 28% or more index；For these defects, so we design the low cigarette resistance of a kind of high oxygen index (OI) of in-car decorations, strong self-extinguishment PVC Combustible material is necessary.
Summary of the invention
The purpose of the present invention is to provide a kind of high oxygen index (OI) of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material, plasticising While improve flame-proof smoke-suppressing, component is nontoxic and will not injure human body, greatly improves security performance, while in mixing process It is not in viscous wheel phenomenon, oxygen index (OI) can reach 29-30%.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of high oxygen index (OI) of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material, including gelatinization layer, foaming layer and base fabric, It is connected between the gelatinization layer and base fabric by foaming layer, and logical between the gelatinization layer and foaming layer and base fabric and foaming layer Cross glue layer bonding；
Wherein, the gelatinization layer is grouped as by the group of following parts by weight: 100 parts of basic polyvinyl chloride resin, the plasticising of DPHP or 911 37 parts of agent, 30 parts of phosphate plasticizer, 3 parts of soybean oil, 2 parts of stabilizer, 3-5 parts of colorant, 15 parts of antimony oxide and hydrogen-oxygen Change magnesium and compounds 50-60 parts with aluminium hydroxide；
The foaming layer is grouped as by the group of following parts by weight: 100 parts of basic polyvinyl chloride resin, DPHP or 911 plasticizer 37 Part, 30 parts of phosphate plasticizer, 3 parts of soybean oil, 2 parts of stabilizer, 3-5 parts of colorant, 15 parts of antimony oxide, magnesium hydroxide with Aluminium hydroxide compounds 50-60 parts and foaming agent 3-5 parts.
As a further solution of the present invention: the basic polyvinyl chloride resin in the gelatinization layer and foaming layer component is respectively glue Change layer and foaming layer respectively dedicated PVC resin powder.
As a further solution of the present invention: the base fabric is resistance polyester fiber knitting fabric or cotton class and the looped fabric high containing cotton.
Beneficial effects of the present invention: plasticizer is by DPHP or 911 plasticizer and phosphate plasticizer two parts, phosphate Class plasticizer mainly improves anti-flammability, while playing elasticizer plasticizing, and the life smoke of polymer is mainly effectively reduced；Soybean Oil, stabilizer and colorant are standard recipe substances, and antimony oxide is main fire retardant matter；The hydroxide of 50-60 parts of compoundings Magnesium and aluminium hydroxide mainly improve anti-flammability with above-mentioned fire-retardant coordinative role, and still further aspect is compounding material resolution Heat is enough absorbed, point of origin is extended, decomposition product is vapor and magnesia, aluminium oxide, and vapor can take away amount of heat, Aluminium oxide and magnesia are refractory materials, can play the role of flame-retardant smoke inhibition, in addition, both ingredients be all it is nontoxic, will not Human body is injured, while the 50-60 parts of magnesium hydroxides compounded and aluminium hydroxide are not in viscous wheel phenomenon, this material in mixing process Material oxygen index (OI) can achieve 29-30%.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality Applying example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is general Logical technical staff all other embodiment obtained without creative efforts belongs to what the present invention protected Range.
A kind of high oxygen index (OI) of in-car decorations, strong self-extinguishment PVC low-smoke and flame retardant material, including gelatinization layer, foaming layer and base fabric, It is connected between gelatinization layer and base fabric by foaming layer, and passes through glue layer between gelatinization layer and foaming layer and base fabric and foaming layer Bonding；
