Abstract
A kind of self-extinguishment plastics, are related to a kind of flame-retarded plastic, and the self-extinguishment plastics are formulated in mass ratio are as follows: 100 parts of plastic raw materials；120-175 parts of light magnesium carbonate；And/or 0.2-1 parts of antioxidant；And/or 1-3 parts of lubricant；Plastic raw materials, light magnesium carbonate, and/or antioxidant, and/or lubricant are kneaded according to formula, are granulated or are made product after mixing.Fireproof self-extinguishment plastics will be made after plastics, light magnesium carbonate, and/or antioxidant, and/or lubricant mixing in the present invention, can be used for building materials and cable material.
Description
Technical field
The present invention relates to a kind of flame-retarded plastics, more particularly to a kind of self-extinguishment plastics.
Background technique
With the sharp increase of urban population, skyscraper, hotel, large supermarket, hospital, station, airport are continuous
Increase, subway, tunnel and large-scale place of public amusement, public transit facility are also sharply being increased, the importance of security against fire
It shows especially out；In particular how in the case of fire, guarantee house security within a certain period of time and ensure electric power and communication
It is unimpeded, it tries to gain time precious to one to greatest extent, reduces the injures and deaths of personnel and the loss of lives and properties, be that people constantly explore
Project.
The cigarette poison harmfulness generated in fire mainly toxic property, dim light, phobic, smoke damage, environmental pollution.And
The harm that drop combustion occurs after combustion for plastics shows further expansion fire dangerous situation, and rescue difficulty is enabled to increase.
Therefore introducing self-extinguishment fireproofing technique in the plastic seems non-to reach the harm such as reduction cigarette poison, drop combustion and Plastics Combustion
Often important, self-extinguishment plastics can automatically extinguish the plastics of burning, will be minimized the danger in household.
Summary of the invention
The purpose of the present invention is to provide a kind of self-extinguishment plastics, the present invention by plastics, light magnesium carbonate, and/or antioxidant,
And/or fireproof self-extinguishment plastics are made after lubricant mixing, it can be used for building materials and cable material.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of self-extinguishment plastics, the self-extinguishment plastics are formulated in mass ratio are as follows:
100 parts of plastic raw materials；
120-175 parts of light magnesium carbonate；
And/or 0.2-1 parts of antioxidant；
And/or 1-3 parts of lubricant；
Plastic raw materials, light magnesium carbonate, and/or antioxidant, and/or lubricant are kneaded according to formula, is granulated or makes after mixing
At product.
A kind of self-extinguishment plastics, the plastics include EVA, polyolefin, ABS, PE, PVC, PS, PMMA.
A kind of self-extinguishment plastics, the molecular formula of the light magnesium carbonate are MgCO3, greater than 90.0%, granularity is purity
200-100 nanometers of mesh.
The advantages and effects of the present invention are:
The present invention has simple production process, and product has excellent self-extinguishment, can meet industrialized mass production requirement；It produces
The source of product is wide, cheap, greatly reduces plastics overall cost, improves product competitiveness.The present invention can make burning
Plastics self-extinguishment reduces hidden fire-fighting danger.It can be used for building materials and cable material.
