Description

A kind of fire-retardant nylon PA66 modified engineered plastic goods

Technical field

The utility model relates to a kind of fire-retardant nylon PA66 modified engineered plastic goods, belongs to modified engineered plastic technical field.

Background technology

Engineering plastics refer to that hot strength is at more than 50MPa, bending modulus at more than 2GPa, impact strength at more than 60J/m, Long-Time Service temperature more than 100 degrees Celsius, for the plastics of the industries such as automobile, machinery, electronic apparatus.

Modified engineered plastic, refers on the basis of general-purpose plastics and engineering plastics, through filling, the method processing such as blended, enhancing, improves the plastic products of the performance of the aspects such as anti-flammability, intensity, impact resistance, toughness.Common plastics often have it self characteristic and defect, and modified plastics changes character to plastics exactly, and basic technology comprises: 1, strengthen: by glass fibre etc. with plastic blend to increase the mechanical strength of plastics.2, fill: by the fillers such as mineral and plastic blend, the character such as the shrinkage factor of plastics, hardness, intensity are changed.3, toughness reinforcing: blended with the toughness improving plastics by adding flexibilizer to common plastics, the product after toughening modifying: rail pad.4, fire-retardant: to add fire retardant to inside common plastics resin, plastics can be made to have flame-retarding characteristic, and fire retardant can be the compound system of a kind of or several fire retardant, as bromine+antimony system, and phosphorus system, nitrogen system, silicon system, and other inorganic fire-retarded systems.5, cold-resistant: to increase plastics intensity at low temperatures and toughness, the black brittleness that general plastics are intrinsic at low temperatures, makes to apply in low temperature environment limited, needs to add some low temperature resistant flexibilizer and changes plastics fragility at low temperatures, the plastics such as such as bumper, General Requirements resists cold.

PA is as most important kind maximum in engineering plastics, there is very strong vitality, mainly be that it modifiedly realizes high performance, next is that the industries self such as automobile, electrical equipment, telecommunication, electronics, machinery are more and more stronger to the high performance requirement of product, related industry develop rapidly, facilitate the process of engineering plastics high performance, make it play more and more important role.Flourish along with the industry such as domestic automobile electric and electronic, the requirement of people to material is more and more higher, and the demand of modified engineered plastic will significantly rise, to the intensity of modified engineered plastic and the performance requirement such as fire-retardant more and more higher.

Summary of the invention

The purpose of this utility model overcomes the deficiencies in the prior art part, provides a kind of fire-retardant nylon PA66 modified engineered plastic goods.

Fire-retardant nylon PA66 modified engineered plastic goods of the present utility model, comprise upper, middle and lower three layers, wherein, upper strata is the first fire-retardant nylon PA66 modified engineered plastic thin layer (1), lower floor is the second fire-retardant nylon PA66 modified engineered plastic thin layer (2), intermediate layer is clathrum (3), the first described fire-retardant nylon PA66 modified engineered plastic thin layer (1), clathrum (3) and the second fire-retardant nylon PA66 modified engineered plastic layer (2) are connected as a single entity, described clathrum (3) is meshy fire retardant fabric, described meshy fire retardant fabric is formed by polypropylene fibre warp thread and aramid fiber weft yarns.

Preferably,

Described clathrum (3) is rhombus, rectangle or square.

Described clathrum (3) has one or more layers.

The characteristics such as fire-retardant nylon PA66 modified engineered plastic goods of the present utility model have excellent anti-flammability and erosion-resisting characteristics, high rigidity grade, low water absorbable, good fluidity, any surface finish, easy processing.Can be used for processing switch, connector, fuse box, coil rack, military project and electronic product.
