And uniformly mixing the potassium perchlorate powder, the potassium chlorate powder and the potassium manganate powder according to the weight ratio to obtain mixed powder, filling the mixed powder into porous sand to obtain the fuze sand 4, and wrapping the fuze sand 4 by using a wrapping layer. The oxidant is separated from the phosphorus, the sulfur and the realgar, and the safety of the toy gun is improved.

The wrapping layer is made of a material which does not directly have chemical reaction with potassium perchlorate, potassium chlorate and potassium manganate or has good oxidation resistance, and comprises fiber paper and an oxidation-resistant film. Potassium perchlorate, potassium chlorate and potassium manganate are strong oxidizers, have strong oxidative corrosivity, and are easy to react violently with reducing substances. The fuze sand 4 is wrapped by the fiber paper and the oxidation resistant film, when a toy gun is collided to generate heat, the potassium perchlorate, the potassium chlorate and the potassium manganate are decomposed and generate heat simultaneously, the potassium manganate is decomposed to generate manganese dioxide, the manganese dioxide is used as a catalyst, the decomposition speed of the potassium perchlorate, the potassium chlorate and the potassium manganate is promoted to be faster, the potassium perchlorate, the potassium chlorate and the potassium manganate can be decomposed to generate a large amount of oxygen in a short time, the fiber paper is broken through, the oxidation resistant film is formed into a first explosion, the first explosion bursts substances in the fuze sand 4 to be flushed to a mixture of phosphorus, sulfur, male sulfur and river sand, the phosphorus, the sulfur and the male sulfur have a mixing effect in the potassium perchlorate, the potassium chlorate and the potassium manganate, the severe chemical reaction is generated along with the generated heat and oxidation, a large amount of gas is generated in a short.

The porous sand can be made of inorganic brittle materials such as pottery clay, electronic ceramics and the like, and the inorganic materials can well preserve potassium chlorate, potassium chlorate and potassium manganate from chemical reaction. The pottery clay and the electronic ceramic product can control the impact resistance of the porous sand, and in the embodiment, the collision damage rate of the porous sand is lower than 50% at the speed of 20m/s, lower than 10% at the speed of 15m/s, and 0 at the speed of lower than 12 m/s. In the transportation or use process, under the condition of considering air resistance, when this embodiment toy big gun does not give the initial velocity, fall and can not blast.

Air resistance f = kv²K is a constant and v is the instantaneous velocity.

Total force F = mg-kv²Acceleration a = F/m = g- (k/m) v²And a = v' (derivative of v) = dv/dt so dv/dt = g- (k/m) v²Integrating to obtain: where ln = (mg/√ k) [ (1+ e) } e, there is a case where v = (mg/√ k) √ mg) = -2t √ (kg/m) √ represents a root number^α)/(1-e^α)]in this case, α = -2t √ (kg/m) in this manner, a v-t relationship is obtained.

The porosity of the single-layer paper of the packaging paper cylinder 1 is 0.35-0.6.

The packaging paper tube 1 is formed by wrapping 2 layers or 3 layers of single-layer paper. The porosity and the wrapping layer number of the packaging paper tube 1 reduce the sealing performance, reduce the air pressure when the toy gun explodes and improve the safety.

Example 2:

The difference between the example 2 and the example 1 lies only in the preparation method of the fuze sand 4, which is specifically as follows:
